Benchmark Technologies’
Grayscale Photomask Technology

Benchmark has many years of designing / fabricating binary, half-tone gray scale photomasks. We use proprietary pixelization programs and sub-resolution pixel sizes, which have been proven by the industries,  to create gray levels for different kinds of needs.

Technical Specs:

• Use glass (or quartz) and chrome, cost-effective
• Dark area > 3 OD, clear area = 0 OD
• Various mask sizes, up to 9 inches
• Standard pixel size on mask: 1 um (we can make it much smaller for higher resolution / smaller feature sizes)
• Gray levels: depend on feature size and pixel size.
