Identifying Wafer Doping - Hot Point Probe Test

[ngneer999]

You can see what I've been doing off and on since 1974 (high school) at semproco (dot) com That's me on the "History" page

Recently we have been grinding the wrong flats on wafers on purpose for SOI since the flats need to align on the two wafers. If the device is 'n' type and the handle is 'p', one of them needs to have the wrong flats. Of all the type testers I use, the hot probe is the most reliable.

@ngneer999 Very interesting. Sounds like we should chat about semiconductors someday.
