Chip Business Picks Up In Japan
By Kenji Tsuda - 16 Dec, 2014 - Comments: 0

Japan's semiconductor business is showing signs of recovery after several years of slumping sales due to an overall market recovery, the favorable exchange rate for the yen, and ongoing business restructuring. Consider Renesas, for example. The company went through several downsizing phases, causing a decline in semiconductor sales by 3.9% to 199.6 billion yen ($1.69 billion) in its fiscal Q... » read more

Bluetooth Adoption To Grow With IoT

From a refinement standpoint, Toshiba/SanDisk is the current market leader, but this group is behind everybody else in 3D technology (Figure 1). Samsung began to ... » read more

All Aboard The Silicon Carbide Train…Literally
By Kenji Tsuda - 08 Sep, 2014 - Comments: 0

There were numerous announcements regarding power semiconductors at Techno-Frontier 2014, which was held last month in Tokyo. This year, one of the big stories was power semiconductors—for power and batteries, motors, and thermal designs—and the debate around cost is becoming much more frequent for silicon carbide. One feature article last month on the Kyoto economy in Nihon Keizai Shimb... » read more

Moving To Wide Bandgap Chips
By Kenji Tsuda - 05 Sep, 2014 - Comments: 0

The search for new materials to replace CMOS has been in full swing for decades, but in spite of successes in limited niche markets, bulk CMOS remains king. That’s beginning to change, however, as CMOS runs out of steam at advanced process nodes and as the priorities of chipmakers change from pure performance to energy efficiency. And for such applications as automotive electronics for hyb... » read more

Fujitsu officially announced its intention of reorganizing its semiconductor manufacturing businesses, including dividing the Aizu Wakamatsu factory and Mie factory as branches of the foundry companies. The rest of the organization, including the system memory department and Fujitsu Electronics will become a part of Fujitsu’s semiconductor group. The new Foundry Company will also be a part of... » read more

EUV Light Source Makes Progress
By Kenji Tsuda - 30 Jul, 2014 - Comments: 0

EUV Lithography light source maker, Gigaphoton has developed a laser-produced plasma (LPP) light source prototype model that can produce a maximum of 92 watts. This is more than double the 43 watts produced using a traditional LPP light source. Figure 1 conceptual diagram of EUV exposure.

An Acquisition And A Merged Technology Strategy
By Kenji Tsuda - 29 Jul, 2014 - Comments: 0

A single chip capable of performing two different functions can reduce the amount of wiring needed to just one layer and it can reduce time to market by simplifying the supply chain and the planning process. Nowhere is this more evident than in the LCD chip market, where two different manufacturers were used to supply chips for touch panels. But an effort to consolidate them into a single ch... » read more
