A Massive Chip Shortage Is Hitting the Entire Semiconductor Industry

One particular of the ongoing issues these previous several months has been why so quite a few tech items have been so tough to acquire. We’ve made repeated reference to regarded prospective things like COVID-19, economic disruptions, yield troubles, and the affect of scalping bots, but there is a new argument for what’s causing these normal difficulties across so a lot of markets: Inadequate expenditure in 200mm wafers.

Currently, main-edge silicon is invariably manufactured on 300mm wafers. In excess of the past handful of a long time, manufacturers have released greater wafer measurements: 100mm, 150mm, 200mm, and 300mm have all been typical specifications at a single time or another. In the Computer enthusiast area, 300mm wafers have extended been considered remarkable to 200mm wafers, simply because the larger wafer size cuts down waste and commonly enhances the foundry’s output in conditions of chips created for each day.

There are not that several commercial foundries nonetheless devoted to 150mm or smaller sized wafer measurements, but a quantity of foundries however operate 200mm fab traces. TSMC and Samsung both give the node, as nicely as a selection of second-tier foundries. GlobalFoundries has 200mm services, as do SMIC, UMC, TowerJazz, and SkyWater. A great quite a few IoT and 5G chips are constructed on 200mm, as are some analog processors, MEMS devices, and RF remedies.

The parts that we converse about at ExtremeTech, such as GPUs, desktop and cell CPUs, higher-finish mobile modems, and other related products and solutions are only a portion of the silicon that receives designed into equipment, and a lot of distributors you’ve by no means listened to of operate experienced, well-understood designs by lesser, older foundry traces for nominal costs.

200mm was supposed to fade absent as 300mm arrived on the web, and that labored from 2007 – 2014, but the craze reversed thereafter. Clients like constructing on 200mm fab strains due to the fact the production technologies are particularly experienced and the costs are low. A lot of clients don’t get a great deal gain from transferring to decrease geometries, and they want to adhere with the designs they’ve now paid for. Lots of IoT sensors and comparable solutions are for that reason crafted at rather significant procedure nodes. As demand for these goods has developed, 200mm capacity has gotten tough to e-book. Substantial foundries like TSMC have been sluggish to increase new 200mm potential, and 200mm utilization was now superior at quite a few fabs in advance of the pandemic strike.

450mm wafer ramp

This outdated graph describing how *450mmwafers ended up heading to ramp also demonstrates what analysts anticipated to come about to 200mm shipments. After 2015, 200mm demand began escalating all over again, although 450mm wafers never ever introduced.

I really don’t want to give the perception that practically just about every foundry with 200mm capability is jogging all-out, but it takes a significant total of time and income to port styles to a new fab. A organization with a chip created for Foundry A’s production line would likely encounter sizeable expenses to port the same chip to Foundry B. In some situations, a firm would pay out additional to port a chip to a new foundry/node than it would ever make back from selling it. Not basically each and every 200mm fab is whole, but the pure-perform foundries with major amounts of 200mm capability aren’t getting a great deal difficulties filling it.

The pandemic has been brutally bad for numerous men and women in the US and throughout the globe, but the semiconductor sector has been one of the only shiny spots. That interprets to additional need for chips of all types, which increased the strain on a provide chain that was now managing as quickly as it could.

“It’s an interesting situation this 12 months. Not only is 200mm in demand, but there is also demand in basic for trailing-edge and specialty goods. It is ability, CMOS graphic sensors, RF, and these sort of items,” Risto Puhakka, president of VLSI Exploration, informed SemiEngineering . “There is also a division in the market. If you are IDMs like TI, NXP, or the common analog guys, 2020 has been challenging. The industrial, automotive, and electric power marketplaces have been in a tough area that is been impacted by the coronavirus. But at the exact time, foundries are booming. The foundries are addressing what I would connect with the shopper marketplaces.”

Need for Wi-Fi and Bluetooth chips has skyrocketed, main to shortages of equally. Demand for automotive electronics has enhanced a lot more quickly than predicted. Huawei soaked up a remarkable quantity of production ability earlier this year in advance of it was slash off in early September, and manfucturers like Xiaomi tried out to get advantage of the company’s weak point with amplified component orders of its possess. In the US, need for PCs has been considerably bigger.

This may well be component of the respond to to why it’s so hard to get a lot of products proper now. It is not just mainly because COVID-19 scrambled offer, it is simply because it at the same time screwed up desire. Blend that with the will need for new laptops to tackle remote learning, new console launches, a much-anticipated GPU start or two, and COVID-19, and Huawei, and now a common 200mm scarcity, and it’s a lot easier to see why the global industry does not appear to be running very easily. A different 220,000 wpm (wafers for every thirty day period) well worth of 200mm potential is expected to occur online in 2021, with full potential of six.4M wpm across the planet.
