This experiment is to determine if the time between the SC1 clean and when the wafers get deposited matter. Currently there is suspicion that an SC1 from an RCA clean should at RIT should be done right before deposition, . So what is done typically is that lithography steps are done weekly at RIT to…
Based on Barrett’s array set up for discoloration, I set up an array experiment to check the discoloration effects between the new and old system ( 2e-7,AJA vs the older 7e-7 CVC ). The wafers from each had a bit of the wafer with different treatments (900C RTP,1000C RTP and Amorphous). To incorporate the maximum…
I’ve been working with the Corning transwell inserts and our SepCon units a bit recently. The addition of the Dremel last week has allowed better control while cutting the transwells, even without the right angle attachment (which will allow cutting in the “drill press” mode). I attached a picture of the process and final unit….
Yesterday Henry and I went over to RIT to perform anodic bonding and parylene deposition using the new membrane configuration of W619 (with the etched trenches for our capillary tubing). I just wanted to post a summary of the process that was done yesterday, as we encountered numerous problems, in the hopes that we can…
A few weeks ago Dave dropped of a humidity monitor for the third floor equipment room. Since then I have been recording the humidity every time I run a UV Ozone process for PDMS-glass or PDMS-pncSi bonding and there seems to be a correlation between the two. Over the last week there seems to be…
Yesterday I started a test to try and reproduce the results Henry was able to obtain with a closed flow system last week. Using four samples (W619) I ran the UV Ozone bonding process and allowed them to sit over night. This morning I found that only one of the four samples was bonded; recently…
I talked with Jim last Friday about a second possible dialysis system using PDMS bound to a glass cover slip. I made a batch of PDMS and let it cure at room temperature over the past few days. Jim had suggested I try bonding the PDMS to a glass cover slip using the UV/Ozone system…
Electron Beam Evaporator Protocol (V_1.0) – Lingyun Here is the first version protocol of the electron beam evaporator at RIT clean room. There is not too much to put down here – the best way to learn this is to attend the training facing the real machine tool. I will try to provide some photos…
Below is an image of HUVEC grown on RTP treated W303 for 72 hours. The cells were seeded at high density and therefore reached confluence prior to day 3. The first row shows the membrane area of the sample; the membrane is not intact. The second row shows the edge of the sample. Live and…
