Title: Takahiro Tsukamoto: Innovator in Semiconductor Technology
Introduction
Takahiro Tsukamoto is a prominent inventor based in Fuchu, Japan. He has made significant contributions to the field of semiconductor technology, holding 2 patents that showcase his innovative approach to manufacturing semiconductor laminated films.
Latest Patents
His latest patents include a manufacturing method for semiconductor laminated film and a semiconductor laminated film itself. The semiconductor laminate film features a silicon substrate with a semiconductor layer that contains both silicon and germanium. This layer is characterized by a surface roughness of Rms of 1 nm or less. Furthermore, the semiconductor layer adheres to a specific relationship where the thickness (t) is less than or equal to 0.881 times the ratio (x) of germanium atoms to the total number of silicon and germanium atoms in the layer.
The manufacturing method involves producing the semiconductor laminate film by forming a semiconductor layer on a silicon substrate using a sputtering method. This method requires a film formation temperature of less than 500°C, with a pressure ranging from 1 mTorr to 11 mTorr. Alternatively, if the temperature is less than 600°C, the pressure must be between 2 mTorr and 5 mTorr. The sputtering process utilizes a gas mixture with less than 0.1% hydrogen, ensuring that the semiconductor layer meets the thickness-to-ratio relationship mentioned earlier.
