Homebrew spin coater. Programmable RPM with hall sensor, use of hdd motor, ardunio, mini air pump, and quad copter driver board.

Microscope lithography with infinity correction. Use of mylar mask in place of polarizer. Looks like it should be possible to get sub-micron features, though with a small field size. The spectrometer is used for film thickness measurements.

Modified HP4145A semiconductor parameter analyzer with basic probe station. Results were from testing an homemade diode made back in high school.

Got interested in AI and how it can be applied to semiconductor research. I have generated over 36,000 QA pairs on my notes, papers saved, and lectures transcribed, of which I used LoRA to finetune a Mistral model. Happy with the initial results, with plans to expand it.

Photolithography is a dumb hobby and it is the path to madness. 😐

Sputter gun assembled!

New chamber "hat" to make room for the sputter gun

Automation in progress + sub 100nm features?

Microscope auto-focusing :)

Assembling the sputter coater

Turbo pump bearing replacement

Built a new spin-coater with a custom UI, it makes use of an internal pump for vacuum with just one external cable for power.
