At the last electronics swap meet I picked up some blank Si and what I think are GaAs wafers. There are 3" and 4" Si and 2" GaAs. Some are polished one side, while others are etched to a matte finish.
My question is "what useful thing can be done with them?"
Thanks in advance for your valuable suggestions!
Usefulness of blank Si / GaAs wafers

Before you throw them away, use them as practice pieces for cleaving wafers. That way, when you get a nice wafer full of dies, you'll be ready to accurately dice it into smaller pieces for more convenient photography.ray_parkhurst wrote:Seems these are of limited utility.

Haha, soon as I hit "submit" I wondered if that might be the case.
