Since 1975 Valley Design Corp. has been an industry leader in advanced materials processing, as providers of precision lapping
, CNC machining
, grinding and other precision machining services including slicing, backgrinding, wafer and die thinning, optical edge/angle polishing
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 Axis CNC machining equipment can produce such features as thru holes and pockets, corner chamfers and radii, edge chamfers and steps, and complex geometries with tight tolerances. Valley is an ISO 9001:2015 certified manufacturer of substrates, windows, wafers, discs, precision shims, spacers and washers,
< 1mm diameter and hexagonal shaped windows, color glass filters
, flat optical components, and SEMI standard wafers
and custom wafers up to 450mm.
Special capabilities: ultrathin
(<20um), ultraflat (1/10 wave), superpolishing (<5 Angstroms), tight tolerances +/-0.5um, parallelism to 0.25um, TTV < 1um. We process parts sized from small die 0.127mm square to large geometry lapping and polishing up to 4 feet in dimension. Optical and semiconductor materials processed: Fused Silica, Quartz, Glass, Pyrex, Sapphire, 96% and 99.6% Alumina, Aluminum Nitride, Ceramics, Crystals, Silicon, Stainless Steel, Aluminum, Molybdenum, Germanium, Macor, Ferrites and many others. Many materials are in stock from our extensive inventory
. Products: Standard and custom sized substrates, windows, wafers, discs and flat optics of various materials, large geometry ceramics, precision shims and spacers
, witness samples, SEMI standard wafers
and dummy wafers up to 450mm diameter, standard and custom color glass filters
, wafer and vacuum chucks, lenses and filters, prisms and wedges, large metal mirrors, lapping and polishing of valve and seal components.
Applications and Industries served: Microelectronics, electro-optics, photonics, semiconductor, MEMS, nanotechnology, thin-film circuits, and microfluidics applications for medical, aerospace, test & measurement, communications, defense, petroleum/natural gas/nuclear/steam/vapor industries. Valley also routinely collaborates on R&D projects for both industrial and educational applications. Valley operates over 25,000 square feet of manufacturing facilities in Shirley, Massachusetts and is partnered with sales representatives in Germany, France and Scandinavia for projects taking place in Europe. Customer service representatives are available Monday - Friday from 8:00 EST to 5:00 PST.
