Mosfet mist?

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.

Magfan what probers and testers have you worked on;I am in ate final test.

Never ever worked test /probe. Did some Reliability (1000 hour burn in) on some tests I ran with induced leaks in a vacuum system, but NEVER probe.
I think that would be some valuable information about some of the differences between MOSFET and BiPolar designs.

I was into diffusion.....oxide growth (insulator) and implant diffusion. Also spent lots of time with metalization. Aluminum interconnects and various backmetals and some platinum silicides. I also worked in photo / etch but that wasn't where my heart was.

One entire fab I worked in was sold to the Chinese. Every machine, valve, pump, filter, bit of plumbing and microscope. The works right down to the flooring. I even caught 'em photographin the Specification Book.....A VERY NO NO thing to do. BUT, the bosses didn't give a XXX.

Sorry Wolf.....a typological error.

"Mosfet Mist" is a phrase coined by that noted 90's adult film star, Linn Klimax.
