- Chrome Masks for 4700A Wells
Chrome Masks for 4700A Wells
One bundle of three chrome masks on 5x5x0.09 inch 1um-flat quartz (amorphous fused silica) substrates. 0.5um minimum CD with 50nm tolerance and uniformity, 150nm registration tolerance to grid, and zero defects greater than 5um. Four days manufacturing lead-time.
The design pattern consists of transparent hexadecagons in a square lattice. Photoresist will be developed and etched but not stripped. As such, dimensional specifications and defectivity are "best effort" and cannot be guaranteed to the specification.
Your mask order will be released to manufacturing on your approval of the proofs shown here and receipt of order. The tone and orientation of the mask are designated in the lower-right corner of each mask. In this case COLOR represents transparent quartz (white represents opaque photoresist over chrome) and the orientation is chrome-DOWN, looking through the glass.
