Valley Design provides top-quality Silicon wafer polishing services to customers with custom polishing needs, and is able to achieve high level optical surface finishes to < 10 Angstroms Ra.
We have been polishing Silicon wafers for over 40 years, and also provide Silicon dicing services. We can provide any size Silicon wafer in custom dimensions from as large as 450mm to chips as small as .127mm square. SEMI standard Silicon wafers are also available in diameters 2”, 3”, 100mm, 125mm, 150mm, 200mm, 300mm and 450mm. Standard Silicon wafers can be thinned and polished to any custom thickness as thin as 10 microns thick and are available in standard tolerances, or as tight a thickness tolerance as +/- 1 micron.
We have extensive experience with providing silicon polishing and dicing services to clients in a variety of industries, such as research, optoelectronic applications, and product development in sensor and laser applications. We also provide edge-angle polishing for optoelectronic applications, and bonded wafer thinning. We can also thin and polish individual silicon dies and SOI (Silicon Oxide) layers.
