Types of Semiconductors
Broadly speaking, semiconductors fall into four main product categories:
Memory: Memory chips serve as temporary storehouses of data and pass information to and from computer devices’ brains. The consolidation of the memory market continues, driving memory prices so low that only a few giants like Toshiba, Samsung and NEC can afford to stay in the game.
Microprocessors: These are central processing units that contain the basic logic to perform tasks. Intel’s domination of the microprocessor segment has forced nearly every other competitor, with the exception of Advanced Micro Devices, out of the mainstream market and into smaller niches or different segments altogether.
Commodity Integrated Circuit: Sometimes called “standard chips”, these are produced in huge batches for routine processing purposes. Dominated by very large Asian chip manufacturers, this segment offers razor-thin profit margins that only the biggest semiconductor companies can compete for.
Complex SOC: “System on a Chip” is essentially all about the creation of an integrated circuit chip with an entire system’s capability on it. The market revolves around growing demand for consumer products that combine new features and lower prices. With the doors to the memory, microprocessor and commodity integrated circuit markets tightly shut, the SOC segment is arguably the only one left with enough opportunity to attract a wide range of companies.
The Chip Shortage Keeps Getting Worse. Why Can’t We Just Make More? (05/06/2021) | @business
… it takes years to build semiconductor fabrication facilities and billions of dollars—and even then the economics are so brutal that you can lose out if your manufacturing expertise is a fraction behind the competition. …
Manufacturing a chip typically takes more than three months and involves giant factories, dust-free rooms, multi-million-dollar machines, molten tin and lasers. The end goal is to transform wafers of silicon—an element extracted from plain sand—into a network of billions of tiny switches called transistors…
