What is it?

The sources describe model 108T as an insert/lapping carrier type associated with double-sided planetary lapping and polishing machines. It is listed as "108T 9B - S/F / Lapmaster LSP-9 / etc." and the pages state that insert and lapping carriers can be manufactured for wafer sizes up to 12 inches, with the insert-carrier page explicitly listing 3, 4, 5, 6, 8, and 12 inch wafers.
