UniversityWafer Silicon Wafers Helped with an Analysis on Macrophage Activation and Lipid Bilayers
Researchers from the Universities of Tennessee and Arizona used our silicon wafers with a 100nm oxide layer to conduct an in depth analysis on how the migration and activation of microphages can be used to remove a foreign object from the surface of a substrate.
Methods: Silicon wafers with a 100 nm oxide layer were purchased from University Wafer. Lissamine (DHPE) was purchased from Invitrogen. BSPC synthesis was conducted as referenced4. Potassium persulfate and sodium bisulfite (Fisher) were utilized as redox initiators for polymerization. The silicon wafers were cleaned with acetone, ethanol, and water before being treated with piranha solution directly prior to use. Lipid vesicles composed of 1.5 mol% Lissamine DHPE and 98.5 mol% BSPC were prepared as referenced4 and deposited on the cleaned wafers. The bilayer was polymerized by either UV exposure or redox initiation. A bare wafer and a wafer with deposited lipids that were left unpolymerized and dried were used as negative controls. Ellipsometry, contact angle, and fluorescent microscopy were utilized to further characterize the dried bilayers. RAW 264.7 macrophages were cultured on tissue culture plastic and passed at 70-80% confluency. Macrophages were seeded at a density of 100,000 cells/cm2. The cells were cultured for 24 hours and then a live/dead staining kit (Invitrogen) was applied to fluorescently analyze the vitality of the cells. ImageJTM, provided by NIH, was utilized to analyzeThermal Oxide Color Sheet

The Purpose of Growing Thermal Oxide Onto Silicon
- Gate oxide
- Masking material during doping
- To provide protection for the conductors
- To Isolate devices from each other
- A dielectric for a capacitor
How is Thermal Oxide Applied to Silicon Wafers?
- Grown Dry Oxidation - By default dry oxide is grown on just one side of the wafer. Perect for very thin oxide layers
- Wet Oxidation Grown - Wave guides technology and Silicon on Insulator wafers (SOI) can benefit greatly from our thick Thermal Oxide layers. We provide thermal oxide up to 15um in thicknessGrown on both sides of the wafers by default.
- Deposited CVD - When you cannot oxidize Silicon, then you can use Chemical Vapor Deposition to deposit the oxide on top of your substrate.
What are the Factors Effecting Oxide Growth?
- Using dry oxidation (Oxygen gas) or wet oxidation steam
- Pressure
- Temperature
- Lattice Orientation (oxide grows faster on (111) oriented wafers then (100) oriented silicon wafers.
