Lattice Materials has exceptional capabilities in custom Czochralski (Cz) crystal growth in both silicon and germanium. Housed in our Bozeman, MT facility, our staff of talented crystal growth technicians can grow to demanding specifications with precision. We have expertise, ability, and experience growing materials in hard-to-find sizes, unique orientations, custom electrical resistivity, and special optical transmissions.
Custom silicon and germanium crystal growth is one of the most unique and important services that Lattice Materials provides. We can control things very few others can, including:
Infrared Optical Transmission
Relief of Internal Stresses through Annealing
Lattice Materials can grow greater than 13″ polycrystalline silicon and up to 12.5″ (12″ slip free) monocrystalline silicon. We also commonly source larger diameter germanium and silicon ingots, over 17″. Work with us to solve your most challenging material requirements.
Silicon Czochralski Crystal Growth:
Monocrystalline: up to 12.5” Diameter
Polycrystalline: greater than 13” Diameter
Germanium Czochralski Crystal Growth:
Monocrystalline: up to 10” Diameter
Polycrystalline: up to 14” Diameter
Larger diameters available via external sourcing. Floatzone material is also available.
