Goodbye wooden table, the sputtering system has officially moved into the lab with a few new upgrades.

Updated with the raspberry pi touch screen, now I don't need another PC, I just need to shove all the excess cables for the robot in a project box to clean it up

Basic robotics integration for more repeatable photoresist development on small semiconductor samples. Will move the program over to a touch screen RPi 4 for ease of use.

Built a micro-scale @GamersNexus logo in my home cleanroom. Fan-made, not affiliated; just for fun.

Needed DI water for the cleanroom shed, fixed a water polished and built a DIY water station in my basement City water -> Water Softener -> CF/RO system -> resin filter -> elga water polisher = DI water <3 PFA containers to keep it DI and transport to/from shed

Constructed over the course of a few months in whatever free time I could find. Learned lots of new skills along the way. Key factors are cleanroom grade flooring, epoxy painted walls, positive pressure filter air intake, and lots of airflow with 2 FFUs.

Sputtering system I built into a wood table haha, working on extruded Al build before I add to the lab

RIE etching with flourine based gases with modified desktop sputter system.

Custom spin coater to coat the resist

Lithography through custom i-line stepper from a modified microscope. Can do dry sub-micron or immersion for down to ~100nm (though with hit to field size)

Class 100 Cleanroom Shed I Built For Semiconductor R&D :)

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.

Turbo pump bearing replacement

Assembling the sputter coater

Microscope auto-focusing :)

Automation in progress + sub 100nm features?

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

Sputter gun assembled!
