Isn't it almost like a taboo to handle Si wafers using metal tweezers or metal things in general?!
Nonetheless, I now have an idea of how it should be done.

Try that on (111) wafer

Oh, and I almost forgot to mention the fume hood and cleanroom-esque glove box. Those might be built as early as this summer.
I'm hoping to get a serious microfabrication process working in the next year or two. I already have some MEMS designs planned (comb drive is top of the list) that would be very fun to play with :)

@TheSolarmike I am actually planning to make a fairly nice set of tools for my lab. Spin coater is already tested and working, next on the list are:
* CMP system for polishing unpolished wafers / doing damascene patterning
* Vacuum evaporation chamber for aluminum deposition
* Laser direct-write lithography system (blu-ray diode + precision steppers)
* Contact mask aligner / exposure system (405nm H-line or 365nm I-line, both work well with DNQ-novolac photoresists)
-
I hope you make a nano/pico lithographic stepper or a molecular beam epitaxy chamber.

Where did you get the wafer from.

@GalaticTG Ebay and brokers. It's easy to find them.

you put this on vimeo a LOOOONG time ago, didn't you?

@thewii552 I did. I wanted to get all the semiconductor videos on youtube also.
