Si-wafers, ideas?
« on: April 20, 2019, 06:55:07 AM »
Don't know where to put this post but..

I got a bunch of 200 mm Si-wafers. Any good idea what to do with them apart from coasters :)?

DIY solar panel, super CPU, or a really really large brick transistor for the mother of all DRSSTC?

Pics coming soon when I am back from Easter trip.

Sell? I give you for free of course as long as you test their high voltage properties in some spectacular way :)

Assuming you lack access to a clean room, I have heard that simple bipolar transistors are possible to make at home with a diffusion process. However, actually making any active device is going to be difficult, obtaining wafers is the absolute easiest part of the process.

You can have fun cleaving the wafers. If you apply pressure with a hard point in the right orientation relative to the flat of the wafer you can split the wafer with atomic level precision.

Other than that, silicon has pretty good transmission in the IR region. A thermal camera should be able to see through it and a CO2 laser should be able to somewhat shine through it.
