Manager: Garry BordonaroBackup: Michael Skvarla , Edward Camacho
This projection printer uses a g-line (436nm) lens column ( 0.30 N.A.) to provide a 5:1 reduction with a variable field size up to 15mm square. Minimum feature size is <0.9µm. The number and placement of the dies is programmable. Wafer size of 3" up to 150mm can be accommodated, as well as smaller pieces. A customized hand-held chuck system allows rapid change of substrate size. Registered alignment is typically <0.25µm. 5" x 0.090"-thick masks are used. This instrument can be easily converted to function as a GCA 3696 Photorepeater system for exposing photoresist coated glass plates up to 7".
