Latest Patents
Hering-Der Chiou holds a patent for a method of eliminating dislocations and lowering lattice strain. This patent describes a technique for fabricating semiconductor substrates with resistivity below 0.02 ohm-cm. The method involves doping a silicon melt with phosphorus concentrations above 1.times.10.sup.18. Additionally, the silicon melt is doped with a germanium concentration that is 1.5 to 2.5 times that of the phosphorus concentration. This process results in a stress and dislocation-free crystalline boule. The high concentrations of phosphorus induce stress in the crystal lattice, which is compensated by germanium. This innovative approach retards the diffusion of phosphorus, ensuring the integrity of the substrate.
