Since 1975 Valley Design Corp. has been an industry leader in advanced materials processing, as providers of precision
lapping,
polishing,
dicing, 4- and 5-axis
CNC machining, grinding, core drilling and other precision machining services including slicing, backgrinding, wafer and die thinning, and
ultrasonic hole drilling. With 15 operational DISCO and K&S dicing saws, our
dicing capacity is one of the largest in the industry. Our 4- and 5-axis CNC machining equipment can produce such features as thru holes and pockets, corner chamfers and radii, edge chamfers and steps, and complex 3D geometries with tight tolerances.
Valley is an ISO 9001:2015 certified, ITAR registered manufacturer of substrates, windows, wafers, discs,
precision shims, spacers and washers, <1 mm diameter and hexagonal-shaped windows,
color glass filters, flat optical components, and
SEMI standard wafers and custom wafers up to 450 mm.
