This website is still under construction. I have done a lot, so there is a lot to upload and present. Check out the subcategories above for a general idea of my passions and skills.

This will be the most recent project of mine.

Design of an Open Source Lab Equipment: Spin Deposition Chamber

In my quest to make an at home semiconductor lab, with dreams of IC fabrication, I have started on one of the key steps to building the lab: The Spin Deposition Chamber.

In order to get thicknesses of my substrates small enough, I need a method of depositing my substrates onto my conductors. My plan for the beginning is to use Indium Tin Oxide conductive glass as my base layer. These can be found in standard microscope slide dimensions, thus I am designing for something about that size.

Many spin deposition chambers reach speeds of around 8000RPMs, this is my first considerations when designing my system. Secondly I would like to have all components either be 3D printed or easily accessible by others; being an open source project, I want others to be able to build and use my system. I also have a secondary requirement, that the design should be flexible enough to use recycled materials, such as nuts and bolts, as well as minimal tool requirements for assembly.

With these design considerations in mind I chose a server fan capable of achieving 8000RPMs. It had the right size and speeds I was looking for, furthermore the design of this fan is fairly common, so many others are able to get their hands on them.

One final note about my design choices, I have seen other spin deposition chambers based on similar ideas, however most of them operate at much lower speeds, and are designed to have the substrate drain into the components. For my design, I have built in a drain tub, so that the solution stays inside the system, and can be removed. This is accomplished by using a petri dish in my design.
