Thoughts

This is quite a late post, but I wanted to finally post my videos that I took over the summer at my Internship. I was working at Alta Devices the entire summer on a project which I called the Wafer Analysis Station (WAS). The company uses GaAs wafers to make their solar cells, and these wafers are used over and over again, as many times as possible. Therefore, the surface must be inspected regularly to make sure it does not need to be resurfaced and is still suitable for the necessary processes.

So, a certain unnamed project that I am working on requires the use of a solar cell to charge some batteries. I got these solar cells from an "over-supply" store in Santa Clara for $4 a piece. As seen in Figure 1, its one of those typical solar cells from a garden lamp that charges batteries during the day and turns some LEDs on at night.

As you can see in my previous blog post, I recently had an interview with Alta Devices in Santa Clara, CA. I took the bus up to San Jose where my dad picked me up in my car and drove me to Alta Devices. I signed in, was welcomed, and then proceeded to meet with five different people at Alta, each for a half hour.
