Which Glass Wafers are Used to Fabricate Microstructures?

A visiting scholar at a major US university was researching microstructures using glass wafers. The researcher was unsure which glass wafer he should use.

Soda Lime Wafers

 Applications: 

  • Where too much heat build up is a problem
  • Hot mirrors to reflect Infrared and Transmitting Visible Light
  • Cold mirrors for trasmitting Infrared (IR) and Reflecing Visible Light

D 263 Wafers 

Applications: 

  • Touch Control Panels
  • Liquid crystal Displays
  • Electroluminescent Displays
  • Solar Cells

There are several types of diameter of 100 mm glass wafer: ID 518, 540, 1943, 1945, 1950, and 3499. They are in different thickness, surface features and prices. For my use, a thickness of 500 mm is Okay, thus ID 518, 540 may be more favorable. I want to inquire that which is difference the two. In my project, the surface of the glass wafer should be as flat as possible, because we need to spin coat photoresist for photolithography. Item#518 Item# 540 Item# 1943 Item# 1945 Item# 1950 Item# 3499.

UniversityWafer Silicon Wafers Used Research on Nanopatterned Antimicrobial Enzymatic Surfaces 

Researchers from Duke University purchased 25 mm x 50 mm silicon wafers with a thickness of 0.13 mm for the purpose of studying the sequential biocidal activity and fouling-release of SEM.

Silicon wafers and glass coverslips (size=25 × 50 mm, thickness=0.13 mm) were purchased from University Wafer.

Preparation of a macroscopically patterned surfaces To examine the adsorption of lysozyme under conditions similar to those employed for backfilling, we prepared a sample in which half of the surface was degraded initiator and half was unpatterned PNIPAAm as shown in Scheme S1.
