Technology executives say this yr’s supply-chain bottlenecks, which have hit components for every little thing from iPhones to Ford F-150s, are notably acute in chips that don’t shuffle zeros and ones. Analog chips deal with incoming details about temperature, sound and electrical present extra like a human would, on a scale with many gradations.
Among the most important analog chip makers is Dallas-based Texas Instruments, based in 1930. TI engineer Jack Kilby is credited with inventing the built-in circuit in 1958.
Students and engineers know TI for its hand-held calculators, which it nonetheless makes. But its $170 billion market capitalization is constructed on its dominance in analog chips, the place it holds 17% to twenty% of the world market this yr, in response to Taiwan-based market analysis agency TrendForce.
While makers of refined digital chips similar to Intel Corp. and Samsung Electronics Co. get many of the highlight, an absence of analog chips costing just a few {dollars} apiece can maintain up provide chains for merchandise with tens of billions of {dollars} in gross sales.
Samson Hu, co-chief govt of Taiwan-based laptop computer maker Asustek Computer Inc., lately lamented that his manufacturing facility meeting strains have been getting disrupted by a scarcity of analog chips managing battery use or amplifying sound results. He used an abbreviation for the time period “built-in system producer,” a category of corporations together with analog-chip makers that design and make their very own chips.
“The uncertainty, as we’ve noticed, lies with a sure massive American IDM firm, ” Mr. Hu mentioned in November on an earnings name. He didn’t identify the corporate, however business officers mentioned that primarily based on Mr. Hu’s description of the large firm’s merchandise, he was speaking about Texas Instruments. A spokeswoman for Asustek declined to remark, and representatives for Texas Instruments didn’t reply to repeated requests for remark.
Mr. Hu mentioned he anticipated provide from the American firm to stay tight till its capability enlargement subsequent yr. TI has mentioned a brand new $6 billion manufacturing facility is ready to open in Richardson, Texas, within the second half of 2022.
Apple Inc.’s chief govt, Tim Cook, talked in an October earnings name concerning the billions of {dollars} in gross sales alternatives Apple is shedding as a result of components shortages imply it may well’t make sufficient iPhones and different gadgets. Mr. Cook referred to “legacy nodes,” a time period for older manufacturing processes that encompasses analog chips and a few digital chips.
“The chip scarcity is occurring on legacy nodes,” Mr. Cook said. “Primarily we buy leading-edge nodes, and we’re not having issues on leading-edge nodes. But on legacy nodes, we compete with many different companies for supply.”
Besides Texas Instruments, main analog-chip makers embody Analog Devices Inc. of Wilmington, Mass., and two European corporations, Infineon Technologies AG and STMicroelectronics NV.
Industry executives and analysts say TI’s issues in assembly demand resemble these of different corporations however that it tends to get extra consideration due to its main place.
Texas Instruments says it’s doing its finest to serve clients and acknowledges that some aren’t getting every little thing they need. “Clearly, we’re properly under the place we wish to be” in stock, mentioned Chief Financial Officer Rafael Lizardi in an October earnings name.
The firm has new capability within the works that it says would require tens of billions of {dollars} in funding, with development beginning subsequent yr on two factories in Sherman, Texas.
At a September investor convention, Chief Executive Rich Templeton cited this highway map in asking for persistence. “You can not change your capability footprint in substantial methods inside a yr or two,” he said. “We’d love to have more capacity now. But there’s a lot of things in life you’d love to have.”
Texas Instruments has 15 manufacturing websites world-wide. Apple contains TI on its provider record and names eight TI places, together with Texas, Maine, Taiwan, Japan and China’s Sichuan province. People concerned within the Apple provide chain say TI components have been one think about shortages of merchandise such because the iPhone this yr. Apple declined to remark.
TrendForce, the analysis agency, mentioned in a December report that analog-chip makers have a backlog of orders from automotive clients stretching to the tip of 2022. Consumer-electronics makers are additionally coping with monthslong waits and better costs, it mentioned.
The world’s greatest and most dear chip makers—Taiwan Semiconductor Manufacturing Co., Samsung and Intel—have spent tens of billions of {dollars} on new capability. Generally these chips have remained plentiful.
Yet of the 50 or so chips crammed into the newest high-end smartphones, solely 4 or 5 fall into the modern class, say executives and analysts within the business. The others embody analog chips that carry out duties similar to powering the telephone’s show or managing its battery charger.
The analog-chip makers are likely to design, manufacture and promote chips themselves, which is why they’re included within the class of built-in system producers. Advanced digital chips, against this, are sometimes designed by one firm and made by one other, sometimes a specialised “fab” similar to TSMC.
In quantity phrases, about 80% of the world’s semiconductor manufacturing comes from IDMs, mentioned Zhao Haijun, co-chief govt of China’s greatest contract chip producer, Semiconductor Manufacturing International Corp.
At an industrial discussion board in November in Shanghai, Mr. Zhao mentioned main IDMs have been 4 to 5 months behind in assembly demand and normally didn’t construct a lot wiggle room into their plans.
“A scarcity of 5% might result in a crazily surging value,” he said. “This is precisely the result of inflexibility along the supply chain.”
Yet analog-chip makers have been cautious about increasing due to the business’s historical past of booms and busts. Texas Instruments executives have mentioned they wish to be disciplined in addressing buyer demand.
“At some level, they’ll have an excessive amount of product, and that’s what creates the cycles in our business,” said TI’s investor-relations head, Dave Pahl, on an earnings call in October. “So it won’t surprise us if the cycle comes to an end at some point. We’ll be prepared for that.”
