Moore's Second Law in the Age of Devices

NEW YORK ( TheStreet) -- Since 1982, I have been writing about Moore's Law, the idea that semiconductor chips can get better-and-better, faster-and-faster. ( Intel ( INTC) now maintains the original 1965 Gordon Moore article on its Web site.)

But there has always been a corollary, what I call Moore's Second Law. As chips get more complex the cost of building a plant to make them, called a fabrication plant or "fab," also rises.

Thus in this century Moore's Second Law has caused chip companies to go "fabless." Most of America's new chip leaders, like Qualcomm ( QCOM) and Nvidia ( NVDA), are absolutely fabless. (Qualcomm's market cap recently passed that of Intel.) Intel's most dangerous competitor, ARM Holdings ( ARMH), does nothing more than license chip designs to others, like the A5 chip in your iPhone. It's essentially a software house.

Moore's Second Law has had another impact: Most production has moved to the Far East. Even Intel and Texas Instruments ( TXN), the best-known American chipmakers, have plants there. The center of the chip-making world is now Hsinchu, Taiwan, 90 minutes from Taipei by road, the home base of Taiwan Semiconductor.

In the age of devices, Intel is being killed at both ends. On the design end, fab-less outfits can deliver custom designs that give phone and tablet companies control of their customers. On the production end, TSMC has cost advantages.

So when Apple ( AAPL) decided recently it had to diversify away from Samsung for components, as CNET reported , because Samsung also makes devices and is actually beating it in that market, it went to TSMC first. It even made noises about dropping Intel from its Mac line, again as CNET wrote , in favor of the ARM-based design used in the iPad and iPhone.

The growing dominance of TSMC and fab-less chip companies, driven by Moore's Second Law, has helped move Apple's entire supply chain toward Taiwan.

American companies are being pushed into secondary roles. Texas Instruments makes chips for the new Lightning connector, which MacRumors thinks contains security software preventing third-party connectors from working , and power management chips for the iPhone 5. But that's it.

As a result of being pushed to the sidelines by the device world's largest purchaser, TI is losing top designers to Apple, according to TechnoBuffalo , and considering sale of the mobile unit to its largest remaining customer, Amazon.Com ( AMZN), as CNET reported last month.
