For instant, a 250nm wafer die Design, its corresponding SEMI Standard M24: Flatness per Site (SFSR) of 0.2m at site size 25 x 25mm. What is the standard wafer size? OVERVIEW GUIDE TO SEMI STANDARD FOR 450 MM WAFERS Author: AUXILIARY Subject: SEMI AUX023-0915 Notch/ Flats. Primary flat on (01 T) plane 0.5. The tolerance of the diameter is typically +/- 0.5 mm. The SEMI-0302 PDF file is 50 pages long and . However, it is common that 150-mm and smaller wafers deviate from the standard having only one flat, and the flat length may be shorter than specified in the standard. WaferPro offers Prime, Test, Monitor, SEMI standard, and customized silicon wafers in all diameters from 2 to 300mm.
