Large-Diameter Crystal Growth
Our focus is large-diameter products, an integrated technical process and continued process development. Alongside stable production of 450 mm diameter products, we are developing and evaluating processes for 600 mm and larger products.
Material Forms & Machining
From monocrystalline silicon crystals to solid, cylindrical and ring blanks, machining routes and material requirements follow component drawings.
Silicon Component Machining
Confirm outer and inner diameters, thickness and critical geometric tolerances against etch-component drawings. Grind and precision-machine the selected material form, then inspect according to the technical agreement.
