Barrett had discovered that growing endothelial cells on pnc-si or tranwells causes vacuoles to form. The vacuoles on pnc-si formed only on the free standing areas of the membrane where there are open pores. The background on pnc-si chips showed…

Effects of Allyl Alcohol on Gold flow in Centrifuge
In the past, we have seen allyl alcohol treatment on silicon chips helps retain a low contact angle longer than a purely plasma treated sample does. This helps us maintain gold flow in a sepcon format for a longer period…

Burst Pressure Vs. Temperature of Deposition
Dave deposited a series of wafers last week at different temperatures. SC 166 -SC 173 were deposited between RT and 300C. These wafers had Jess’ E.O mask pattern ( circular sepcon) with single , 3,6 and 9 squares. The wafers…

B.P with Thickness of Material
In an effort to understand the material property using burst pressure, a few key variables have to be analyzed to determine their effect on burst pressure. These variables are: 1) Shape : a) Maximum Dimension of the slot. b) Minimum…

Burst Pressure Vs Thickness Series( 50 nm vs 30nm)
Last week Dave deposited sep-cons ( cell culture mask) with 3 different thickness namely the regular 15nm , 30 nm and 50nm ( SC 142, 143,144). These wafers were characterized and it was noted that the 15 nm had a…

Macro To Represent Wafer Characterization
Charles designed a macro for excel to represent the data gathered from wafer characterization, in a visual format. It is built on VB platform and runs off Microsoft excel. The data is input in a simple fashion by selecting the…

Discoloration CVC vs. AJA Tool
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…
Discoloration Study with Bacterial Media
I performed a test study to see the effect of microbial media’s : LB and BHI Broth on the membrane to check for discoloration. LB Broth : Lysogeny broth,Luria broth or Luria-Bertani broth. Obtained from Sigma and made by dissolving…
