Accomplished
This week, I have continued the fabrication process for our first batch of NMOS. However, challenges were encountered during the ICP RIE process where our chip failed to etch as expected after repeated multiple attempts. During the process, two of our chips were basically destroyed. After some investigation through AFM and a report from the rest of the NMOS group who were successful in doing the RIE, I have since found and resolved the issue.
Progress/Schedule
The previous setback has caused a measurable set back in my schedule. Our initial optimistic goal was to have them done this week, but due to the issue that we encountered, the plan is now to have them sometime this week (Tuesday/Wednesday). On top of that, since Hackerfab is also restoring the process and has a dedicated NMOS team working on it, we have about 6 chips that are planned to be finished by this Wednesday so regardless of my own progress, we should be getting some basic measurements this week.
Upcoming Deliverables
Next week, we should have some devices ready to be measured, and I should be able to fabricate the first batch as I continue to learn and refine the process throughout each try. I will also start the design on the capacitor and resistor components.
