Japan Earthquake Suspends Supply of Raw Material Used in 25% of Chip Production - Memory Segment Hit Hard

An update into the effects on technology companies following the recent earthquake and tsunami in Japan, from IHS iSuppli.

The Japanese earthquake has resulted in the suspension of one-quarter of the global production of silicon wafers used to make semiconductors. Manufacturing operations have stopped at Shin-Etsu Chemical's Shirakawa facility. MEMC Electronic Materials also stopped manufacturing at its Utsunomiya plant. Together, these two facilities account for 25 percent of the global supply of silicon wafer used to make semiconductors. Wafers are thin slices of silicon that serve as the substrate of semiconductor devices. All semiconductors are built on wafers. more

Revealed - Why Motorola Needs the Xoom Back for LTE Upgrades

The IHS iSuppli team of teardown experts has obtained and opened up a brand new Motorola XOOM wireless 3G tablet - model MZ600 - running Google Android 3.0 on Verizon Wireless' CDMA network. The 10.1-inch display, 1.6-pound tablet closely approximates the Apple iPad's dimensions but outdoes its year-old forerunner by including both a 2-megapixel front-facing camera, and a 5-megapixel auto focus primary camera. Unlike the iPad, the XOOM now comes in only one configuration, with 32GB of NAND storage. However, the XOOM makes up for this lack of variety with its powerful dual-core Nvidia Tegra 2 apps processor, ample 1GB synchronous dynamic random access memory (SDRAM) and loads of extra sensors. more

A UV-transparent coating for image sensors

Due to the working environment that camera sensors are sometimes used in, the sensors that convert light into electrical signals (cmos devices) are covered with a silicon nitride coating. This chemical compound forms hard layers which protect the sensor from mechanical influences and the penetration of moisture and other impurities. The protective coating is applied to the sensor in the final stage of cmos semiconductor production. The process is called passivation, and is an industry requirement. more
