Mosfet mist?

How many posters have spent any time in a fabrication facility seeing how semiconductors are made?

Exactly 37.

Thanks Atmasphere. I learned something today. Pls excuse my uninformed sarcasm. I was caught up in a mirthful moment. I will have to scrutinize my 1995 Halfer 9180 for this phenomenon. It uses lateral MOSFETS. I do LOVE the sound, never tiring.

point is, Woof, that some knowledge of how semiconductor devices is made would go a long way to help people understand what they are buying into. Toss in a dose of device physics and than you can talk.

Talking about a particular tech having certain characteristics is generally a no-win with many other factors tossed into the mix.

I worked in-fab since the early 70s, first making quartz lo-frequency oscillators and later CMOS / BiPolar and other integrated devices and still later making discrete HexFets, IGBTs and FREDs. It was a lot of fun, with the first ICs I worked on having 6 or 7 micron geometries on 3" wafers!

But anyway, show me a good design using any device and you'll be hearing good sound. Bad sound can come from any technology.

If anyone has any curiousity about how any of this stuff is made, I'll do my best to answer or find out.

Who you calling "woof?" I've also worked on wafers...I spent the holidays working hard on drinking beer while eating only seeded wafer crackers.
