Today I got to replace the EDP solution. Pretty nasty stuff. As it reacts with the silicon to etch it, a rather nasty sludge builds up, and eventually the whole batch needs to be replaced. I followed all the directions to the T, but Jeong got mad at me for almost throwing some paper towels in the trash after rinsing the container out three times with water. The directions said to throw it in the trash. I suppose I can't win. Not a lot of fun.

I etched another wafer today. On Monday I'm going to look at it under a microscope to see how well it turned out. Cill told me that the next step is to deposit some gold on the wafers to test the thermal conductivity. More stuff to learn.

I beat Red Alert... again. The AI in the game is remarkably simplistic. The last level is supposed to be really difficult, with the enemy dropping reinforcements at your doorstep by boat. Nice thought, except for the part where the boats always drop at the same location, and if you put four tanks on the shore, the boat can't unload and sits there till the tanks kill it. Oh well. It set the standard in 1994 I suppose.

Tyler Northrop came over around midnight and we played some Halo 2 for a while. It was good to talk to him again.

I have a big day of doing nothing tomorrow, so I'm going to bed.
