Title: Innovative Contributions of Manabu Nishimoto in Silicon Technology
Introduction
Manabu Nishimoto, a prominent inventor based in Saga, Japan, has made significant strides in the field of silicon technology. With a total of seven patents to his name, he has played a pivotal role in advancing methods for producing high-quality silicon wafers, essential components in the electronics industry.
Latest Patents
Among his notable innovations are two recent patents that highlight his expertise in silicon wafer production. The first patent focuses on a method for producing a silicon wafer, involving the formation of a silicon ingot through a Czochralski (CZ) method. This process maintains an interstitial oxygen concentration of not more than 7.0×10 atoms per cm and emphasizes precise doping with phosphorus. It further incorporates the formation of a polysilicon layer or strained layer on one surface of the wafer, complemented by a mirror-polished finish on the opposite surface.
Nishimoto's second patent addresses a novel crystal growth method in the CZ process, which employs a specially designed cooling member. This innovation not only enhances the pulling speed but also mitigates the emergence of cracks in single crystals due to excessive cooling. By regulating the temperature of the cooling member to be below 500°C, he ensures high-quality crystal formation, while the dimensions of the cooling member are optimized for efficiency.
