Latest Patents

One of his latest patents is a method of manufacturing a semiconductor device and a fabrication apparatus for a semiconductor device. This method aims to reduce the number of manufacturing steps and enhance the rationalization of the manufacturing line. The semiconductor device is a high-frequency module that is assembled by mounting chip parts and semiconductor pellets onto wiring substrates formed on a matrix substrate after inspection. A defect mark is affixed to a wiring substrate as a block judged to be defective during the inspection of the matrix substrate. In subsequent assembling steps, the defect mark is recognized, allowing the omission of the assembling work for the wiring substrate with the defect mark, thereby streamlining the manufacturing process.

Another notable patent is for a high-frequency power amplifier module and wireless communication apparatus. This invention reduces the number of components in a high-frequency power amplifier. It adjusts the bias resistance ratio according to changes in the threshold voltage (Vth) of a transistor. The high-frequency power amplifier consists of multiple amplifying systems, each with an input terminal for the signal to be amplified, an output terminal, a bias terminal, and a bias circuit connected to apply a bias potential to the amplifying stages.
