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

D263 glass is great for computer, phone high resolution display technology and production. Thin D263 glass panes are also used for lenses, which is often more expensive than the cost of a conventional glass lens.
D263 is also used in mechanical polishing treatments and to manufacture microelectromechanical systems (MEMS) on different substrates. D263 glass wafers are fantastic for the production of high-performance, cost-effective and flexible microprocessors, meeting the high performance and low cost requirements of a wide range of applications
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.
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.
