  • Patent number: 8178365
    Abstract: A semiconductor wafer having IGBT elements and transistors formed on a surface thereof is prepared. Electron beams are emitted all over the surface of the semiconductor wafer. Recombination centers are formed in the IGBT elements and the transistors. ON voltages of the transistors are measured by a measurement device, and lifetimes defined in the IGBT elements and the transistors are recovered by a prescribed annealing treatment. When the lifetimes are recovered, a control device controls an annealing treatment amount in the annealing treatment based on the measured ON voltages of the transistors such that ON voltages of the IGBT elements are each equal to a desired ON voltage. Variations in the ON voltages of a plurality of IGBT elements obtained from the semiconductor wafer are reduced.

  • Patent number: 6735576
    Abstract: Real-time optimization is conducted for a control device having a fuzzy inference system that can optimize characteristics of the control device in real time, by coding parameters used in the fuzzy inference system into chromosomes, and optimizing in real time the output of the control device by subjecting the chromosomes to evolutionary computation. Coding is conducted by (i) revising a matrix of fuzzy rules used in the system by extracting a section from the matrix and coding elements of the section into chromosomes; (ii) modifying the configuration of the fuzzy rule matrix defined by membership functions by coding elements of the membership functions into chromosomes; or (iii) changing a level of an input of the parameters and a level of an output of the fuzzy inference system.
