Latest Patents
Wei Guo Liu holds a patent for a "Method and apparatus for growing semiconductor crystals with a rigid support with carbon doping and resistivity control and thermal gradient control." This patent describes a process where Group III-V, II-VI, and related monocrystalline compounds are grown using a sealed ampoule with a rigid support. The invention incorporates carbon doping and resistivity control, along with thermal gradient control in a crystal growth furnace. The design includes a support cylinder that provides structural support for the sealed ampoule crucible assembly. Additionally, low-density insulating material within the support cylinder helps deter convection and conduction heating. Radiation channels allow for effective radiation heating into and out of the seed well and transition regions of the crystal growth crucible. A hollow core in the insulation material beneath the seed well facilitates cooling in the center of the growing crystal, promoting uniform growth and a flat crystal-melt interface. This results in crystal wafers with consistent electrical properties. Wei Guo Liu has 1 patent to his name.
