The Chip Shortage Has Made a Star of This Little-Known Component (wsj.com) 63

The global chip shortage is giving rise to a small group of little-known companies whose products are increasingly essential to the plans of semiconductor industry titans. From a report: The companies make parts called substrates, which connect chips to the circuit boards that hold them in personal computers and other devices. The components are relatively simple but as vital to a computer chip's operation as the silicon at its core. Substrate manufacturing has long been seen as a backwater of the global chip supply chain. The sector's relatively low margins have led to underinvestment and, in recent months, added to the pain of a global chip shortage that has constrained personal computer sales, caused some auto makers to idle plants and raised costs for electronic devices.

Supplies of substrates used in some of the most advanced chips are particularly tight, and some industry specialists said they could remain in short supply for years. That has made sourcing the products a priority for chip companies including Intel, Nvidia and Advanced Micro Devices and given new clout to the unheralded companies that specialize in making them. "Right now, all you have to do is say you manufacture substrates, and you get business -- it's insane," said Nicholas Stukan, chief business development officer at Zhuhai Access Semiconductor, a substrate manufacturer based in southern China. He said chip makers are begging for supply and are willing to pay much higher prices than usual to satisfy antsy customers. Intel Chief Executive Officer Pat Gelsinger discussed his company's efforts to address substrate shortages in the company's earnings calls this year -- the first time in a decade the topic was featured in any meaningful way in Intel's quarterly results presentation. Mr. Gelsinger is expecting the chip crunch to last into 2023 as the chip industry, including substrate suppliers, boost capacity. Adding a new substrate factory can take a year or two, he said in a July interview. "This is a challenging demand environment," he said.

    • I have a batch of these babies right here. I'm rich! RICH I tell you!

      In all seriousness, though, I started switching back to ATMegas for less computationally expensive stuff because they are still fairly cheap to get and for most of what I need to do they're sufficient.

      It still blows.

    • I'm looking at using one of the bluetooth audio modules from Microchip and lead times on one particular model are are currently October, of 2022.

    • Back in the day, a company called Newtek was the manufacturer of a product called the Video Toaster. This product relied upon a lot of RAM to do its magic. The company was in financial trouble and needed to file for bankruptcy protection. As part of the reorganization, an audit revealed that the company was sitting on a LOT of RAM chips which happened to be in great demand at the time. So they sold off the inventory at top dollar and kept the company afloat.

    • I tend to go pi's, and so far have not seen issues. I recently have purchased pi's, A/D's, opto-switches, R's, C's,opamps, various connectors, RS485 parts, small displays, ... all with no issues. I have been lucky my needs don't seem to be in competition with parts used by others. The STM's are an industrial favorite. I know the pi is not industrial rated, not sure if it is the broadcom part or some other part on the pi board that limits the pi to diy.

The main thing to remember is that these sorts of products manufacture a large batch of chips then store them in a warehouse. When the warehouse is empty, they'll have to wait in line to make more.

        I expect to see some weird prices on ebay or whatever for Pi3 versus Pi4 having wildly different prices, possibly even the 3 being more dear than the 4 for a brief period. I don't know how much w

        Where are you purchasing yours? I tried to order some from my usual U.S. suppliers (Sparkfun, Digikey, Adafruit, Mouser, Newark) a month ago and all showed zero inventory. I've been able to back-fill a bit by substituting other models or buying Starter Kits instead of standalone boards. Some are now available for backorder, with projected ship times in the 4-20 week range.

        • Right you are, just looked on Digikey. They are out and so is adafruit, my 2 normal suppliers. I think I bought my latest batch of pi's 3 months ago, and from digikey that time. I usually keep a couple on hand for new projects and when I am down to my last one order more. I've had a couple fail over the years and since they are now integral to my house, I keep spares.

        The only place I could find that can ship a 2 GB Pi to the U.S. is in Canada. :-/ As far as I can tell, in the U.S., the 2 GB Pi is sold out nationwide. It has been this way for months, and they likely won't become available until next year.

        It's at least possible to get the high-end configurations (4 GB and 8 GB) from *some* sellers, because a lot of people balk at spending an extra $20–40 for more RAM. But even the 4 GB and 8 GB models are sold out from many sellers.

      As a DIY-hobbyist, I have been practicing my skills at designing custom PCBs for various projects and after the pandemic hit, I've noticed that STM32 MCUs have become rather scarse and, where available, stupidly expensive. Before the pandemic, e.g. STM32F103C*T6 MCUs cost only about 0.70â per pop. Now? They're 16â or more! Sure, those parts are quite old, but even the more recent STM32-line MCUs have seen their prices go through the roof compared to what they were.

      No, they won't, because it is fucking stupid.

        So how many billions of dollars have been lost due to broken supply chains? How much is all that unsaleable inventory sitting on parking lots costing auto manufacturers? How costly and inefficient is all that reduced production with sky high demand? One auto manufacturer with the foresight to have a captive supply of semiconductors could have cleaned up in 2021. Instead, they are all laying off workers and closing plants.

        • Given a set of fabs to supply the range of chips needed for a typical auto company, (think from infotainment systems requiring the latest node to ECU's that are probably on .18 or even older) would cost around 100B in investment, I am not expecting GM/Ford to start producing chips anytime soon. The chip industry is very, very, very capital intensive. The chip industry is a boom/bust biz, see Micron.

              • Based on what do you make that assertion? While car makers do not need the leading edge of 3nm or 5nm, TSMC has many fabs at larger nodes which the automakers are using. Those fabs are valued at billions each. Also remember that the capacity of each fab would be essentially idle if they were only producing for an automaker as it would not take long to produce a years supply should an automaker buy them. For this plan to work, an automaker would have to spend billions to buy a fab that would be not spend mu

                    1) TSMC is currently making chips for the automakers so it is the perfect example. 2) Do automakers use the Belgium fab? Why or why not? 3) How much would it cost to buy the Belgium fab. 4) How much capacity does the Belgium fab have?

                    As for 1) and 2), not every fab is identical to every other fab. Some older fabs are not used as they do not and cannot make the product that is required. While automakers do not need 3nm or 5nm product, they contract with TSMC for a reason. Sure they could probably contract

                    • Yes fab is used for automotive. Also know other fabs than TSMC that are used by the big ones in automotive. Did automotive designs in a lot of fabs, including TSMC. I know my stuff. Last design was in an... 180nm process. You know transistors that can shunt amps, can withstand tens of volts. The analog part actually ran with clockspeeds in the kHz domain. Now get off my lawn.

          Ford bought existing businesses. GM did as well in their earlier years.

          Well, that's nice. So which businesses do you suggest the various automakers buy? TSMC? Samsung? Global Foundries? And what makes you think the companies that own the IP for the chip designs wants to sell them? Now the automakers need their own chip designers too? Very efficient! And don't forget, the raw materials needed to fab the chips are also part of the supply chain. Guess every automaker needs to purchase a mine to supply that stuff.

          Ford bought existing businesses. GM did as well in their earlier years.

          TSMC's current market cap is $650B today and was $290B in 2019 [companiesmarketcap.com]. Ford is $50B today and $38B in 2019 [companiesmarketcap.com] and GM is $70B today and $50B in 2019 [companiesmarketcap.com]. So you expect somehow Ford could buy a company that before the current shortage was worth 9X theirs. How? Combined both GM and Ford cannot buy TSMC. That is just one company.

          So how many billions of dollars have been lost due to broken supply chains? How much is all that unsaleable inventory sitting on parking lots costing auto manufacturers?

          Far far less than the $650B that Ford does not have today.

          How costly and inefficient is all that reduced production with sky high demand?

          Every day, stuff happens in the world that no one can anticipate. That does not mean a company spends billions of dollars because you feel they should.

          One auto manufacturer with the foresight to have a captive supply of semiconductors could have cleaned up in 2021. Instead, they are all laying off workers and closing plants.

          And which automanufacturer would do that. Almost no one in many, many industries keeps large inventories. Laying off workers and plants is unfortunate; however, going bankrupt and ceasing to exist because they spent 9X their value is worse.

      • It seems like a large part of the problem is that the microprocessor ecosystem has evolved to mean only a handful of large scale producers, TSMC, etc and based entirely on silicon semi conductors. Will be interesting if any green shoots arise from this supply debacle that are new, different ways of computing.

        While certain parts of the modern auto might need fast silicon (or SiC if you are Tesla) for things like auto-pilots, I'm guessing even a decent infotainment system for a car could get by on a slower a

        • There are other avenues of research for chips; however, for today's chips that means silicon and smaller and smaller feature sizes. The push to smaller feature sizes has meant that many fabs can no longer compete on the leading edge. For example, Texas Instruments' smallest node is 45nm which was introduced in 2007. Their newest node is almost 15 years behind the leading edge.
    • Vertical integration in manufacturing means maximum capital outlay and your profit is amortized along the entire stack. Vertical integration is useful if some absolutely necessary stages are not profitable enough (or at all!) and you can offset it by other stages that are very profitable. But if you have a working supply chain you can offload the less profitable aspects parts of manufacturing and focus on your core business. This means you have less overhead in staff and management as compared to a more int

    Unfortunately, the article neglects to describe just what these magical substrates are or do. So here's some added context:
    * It's not the silicon wafer (either before or after lithography).
    * It's not the printed circuit board that the chip gets soldered to.
    Instead, for certain kinds of chips, it is the thing the silicon die gets attached to so that it can more easily end up on a circuit board. If you do an image search for "microprocessor" [google.com], you'll see a bunch of "chips" that actually look like little circuit boards - often with tiny surface mount components added (usually capacitors). That circuit board-looking thing is the substrate. In its construction it is much like a PCB, in that it has layers with traces, pads, vias, etc. Except that the layers tend to be microns thick and have tightly controlled impedance and dielectric properties; the vias tend to be micron-sized and made by lasers rather than drills. It tends to look a lot more like the metal interconnect layers of the silicon die than a more conventional PCB.

    Depending on the device and the manufacturing process, the die may be adhered and then wire-bonded or, increasingly these days, have miniscule solder balls and attached to the substrate that way. Substrates are largely for handling: as an adapter between the tiny feature sizes of the relatively delicate silicon dies and the more robust (but still small by human standards) feature sizes of PCBs.

    Substrates can also be used, as the images show, as mini circuit boards, putting multiple silicon dies in very close proximity together into a single module, and sprinkling a few passive components (e.g., capacitors) in there to improve performance.
    • Another good way to see the distinctions is to look at UV erasable EEPROMs, you can easily see the silicon chip inside the little window, and the part this article is about is the black part that hooks between the circuit board and the chip. When most people think of chips, they are really thinking about the ceramic or metal substrate, because most people have never seen a silicon chip.

      The substrate is the undoped silicon die. From a supply chain perspective, it is the whole wafer.

        No, the "substrate" is as I described it. From the article:

        Made up of thin copper wire sandwiched in resin, substrates help transmit user instructions to a computer’s chips and relay the answers. They are necessary because the ultrathin wiring that comes out of chips can’t tolerate a direct soldered connection to a circuit board.

    Since it's all people, the same fears applies. Be it toilet paper, substrates, capacitors, resistors, etc... If it goes on a board, or in the production of a chip or a board, everyone and their grandmother are hoarding it now.

    Welcome to 2020.

    • If it goes on a board, or in the production of a chip or a board, everyone and their grandmother are hoarding it now.

      Hoarding suggests people are holding inventory. That is not the case. There are simply a lot of things in short supply with little inventory.

      • The third-party package assembly companies my employer contracts with are now requiring significantly more substrate upfront before they take on work. So it's not little inventory, it's actually large inventory that's the problem.

    I was talking to the owner of a custom wiring-harness manufacturer about the long lead-times for connectors and associated pins. Some stuff is backordered until March 2022. She said that she had to inform a client that the harness they ordered couldn't be completed until the fall of 2022. Then we got into talking about chips shortages and she said that it has a lot to do with a shortage in a particular kind of glass used to make the chips. That glass is also used for COVID vaccine vials. So, combine an overall production slowdown due to COVID with a diversion of a key material to deal with COVID and you have a major problem.

      It is the entire pure silicon "chip" that all integrated circuits are built out of. It's grown into a large rod-shape of pure crystal in a factory known as a foundry. Diameter of 200 mm or 300 mm. Then sliced into shiny flat discs, known as wafers, before being shipped to fabrication factories for the fabrication of the IC.

      There's nothing without the substrate. Everyone is consuming it because it's the bulk material of every IC. It is not used for interconnect at all.

    There is no chip without the substrate.
