Custom growth of silicon and germanium requires precision, expertise, and tight process control to achieve high-quality crystals with the desired properties.
Lattice Materials has exceptional capabilities in custom Czochralski (Cz) crystal growth in both silicon and germanium. We have a team of expert technicians growing crystals in our Bozeman, MT facility.
We have the ability and experience to grow crystals in hard-to-find sizes, unique orientations, custom electrical resistivity, and special optical transmissions.
Custom-grown silicon and germanium are valuable for the semiconductor industry, optoelectronic applications, and for institutions involved in research and development, such as academic institutions, national laboratories, and R&D departments in private corporations.
Custom-grown crystals allow for the tailoring of specific properties to meet the requirements of various applications. Often these applications call for silicon and germanium with precise electrical properties.
Custom growth of crystals is also essential for the following reasons:
Manufacturing custom silicon and germanium boules involves several steps to produce high-quality crystals with tailored properties.
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″.
