Fab tools, packaging/test VLSI Research has released its 200mm wafer fab equipment (WFE) market share figures for 2019. The top three suppliers--Applied Materials, TEL, and ASML—saw growth in the 2019 200mm WFE business. Lam Research was in fourth place, followed by KLA and Canon. In total, 200mm wafer fab equipment sales were $3.6 billion in 2019, declining 5% from 2018, according to the fi... » read more

Improving Reliability For GaN And SiC
By Mark LaPedus - 18 Jun, 2020 - Comments: 2

Suppliers of gallium nitride (GaN) and silicon carbide (SiC) power devices are rolling out the next wave of products with some new and impressive specs. But before these devices are incorporated in systems, they must prove to be reliable. As with previous products, suppliers are quick to point out that the new devices are reliable, although there are some issues that can occasionally surface... » read more

How GaN On SiC Lowers 5G Base Station Costs
By Wolfspeed, a Cree Company - 15 Apr, 2020 - Comments: 0

GaN’s higher efficiency at 5G frequencies compared with LDMOS also means a lower operating cost per bit/second and a lower carbon footprint. Wolfspeed, a Cree company, and dominant player in the GaN on SiC device market, estimates that GaN on SiC can save over 200 W of DC power compared to a system that uses LDMOS power amplifiers (PAs) when operated at maximum average power.

The Ins And Outs Of Silicon Carbide
By Ed Sperling - 19 Mar, 2020 - Comments: 0

John Palmour, CTO at Cree, sat down with Semiconductor Engineering to talk about silicon carbide, how it compares to silicon, what's different from a design and packaging standpoint, and where it's being used. What follows are excerpts of that conversation. SE: SiC is well-understood in power electronics and RF, but is the main advantage the ability to run devices hotter than silicon, or is ... » read more
