Manufacturing Bits: Jan. 21


New high-frequency transistors The Fraunhofer Institute for Applied Solid State Physics IAF has developed a novel high-frequency transistor type—the metal oxide semiconductor HEMT or MOSHEMT. Still in R&D, Fraunhofer’s MOSHEMT has reached record frequencies of 640GHz. MOSHEMTs are designed for the 100GHz frequency ranges and above. Applications include communications, radar and sens... » read more

Power Semi Wars Begin


Several vendors are rolling out the next wave of power semiconductors based on gallium nitride (GaN) and silicon carbide (SiC), setting the stage for a showdown against traditional silicon-based devices in the market. Power semiconductors are specialized transistors that incorporate different and competitive technologies like GaN, SiC and silicon. Power semis operate as a switch in high-volt... » read more
