He studied organic chemistry at Tohoku University in Sendai, Japan. With poor prospects for employment in the field of chemistry, he went to work for Busicom, a business calculator manufacturer. There, he learned about software and digital circuit design. When Busicom decided to use LSI circuits in their calculator products, they approached the American companies Mostek and Intel for help. Masatoshi Shima ultimately worked closely with Marcian "Ted" Hoff and Federico Faggin of Intel to complete the design of the Intel 4004 microprocessor. Organic chemistry is a specific discipline within chemistry which involves the scientific study of the structure, properties, composition, reactions, and preparation (by synthesis or by other means) of chemical compounds consisting of primarily carbon and hydrogen, which may contain any number of other elements, including nitrogen, oxygen, halogens as well...
