Thought for the month

“You know," said Arthur, "it's at times like this, when I'm trapped in a Vogon airlock with a man from Betelgeuse, and about to die of asphyxiation in deep space that I really wish I'd listened to what my mother told me when I was young." "Why, what did she tell you?" "I don't know, I didn't listen.” From The Hitchhiker's Guide to the Galaxy, Douglas Adams, Author (1952-2001)

imec HBT

Belgium based research consortium Imec has developed a heterojunction bipolar transistor device with peak f(max) values above 450GHz as a key enabler for millimetre-wave low-power circuits to be used in automotive radar applications. Imec used a silicon-germanium: carbon heterojunction bipolar transistor process technology which improves device performance by adding small amounts of germanium and carbon to the silicon transistor base. Compared to III-V HBT devices, SiGe:C HBTs combine high-density and low-cost integration, making them more suitable for consumer applications.
