Today I looked at a wafer (391) that had been annealed in the RTP on top of a 6″ wafer substrate. The idea is that the six inch substrate would create a “shadow” around the 4″ wafer which would improve…

We’ve got pores! Unfortunately, we are still being plagued by an unknown contamination that seems to be “eating” away at our membranes. This would explain why we’ve been having a hard time separating. We also observe a strong radial dependence…

Our two O2 regulators arrived this week (it figures we would have two to arrive within a day of each other after waiting for weeks to have one). Tom and Lingyun got to work right away. The image below shows…

Coming to a basement near you by the end of 2008 (assuming no delays that is). Pretty exciting in my opinion. 

Samples are from wafers #316 and 318. This is the first time for wafer scale deposition. Processing conditions:1) chamber base pressure @ 6×10-7 Torr (previously @ 5×10-6 Torr)2) 15nm Ti + 15nm Au, no vacuum break Estimated “cell resistance”: about…

I few weeks ago I posted some flow rate data based on the 100K microcons in which three of the four membranes worked fine and the other appeared to be a “dud”. I pulled the four systems apart and used…

The new smaller EQ setup that Tom came up with were tested in these experiments. The benefit is that there is much less dilution of our filtrates. 500ul of our sample (in these cases we tested 1.0 mg/mL and 0.5…

First Try is detailed in this post. Three membranes from w334 were used to separate depleted serum. As before we see that all of the proteins pass through the membrane, and again we can observe the one middle band that…

This gel shows the separation using two 100k Microcon membranes and 1mg/mL brain extract. 500uL of 1mg/mL brain extract was loaded into the Microcon and spun at 14000g for 5min. 400uL passed through the membrane (100ul remained on top). It…
