Abstract
Shin-Etsu Handotai Company, Ltd.(SEH) was originally established as a silicon denartment of Shin-Ptsu ChPmiral Co Ltd.(SEC). In 1967, being separated from SEC, SEH started as a joint venture between SECand Dow Corning Corporation. The production originally started at lsobe plant (in Annaka City) and then diversified at other plants as its business grew.Currently, Isobe Plant manufactures CZ and FZ crystals, epitaxial wafers, and compound semiconductors. while Naoetsu and Take fu Plants manufacture polycrystalline silicon and CZ crystals. resnectively Naoetsu Denshi Nauann 1iPnchi and SEH Malaysia are specializing in wafer processing so that specialists in each area can work most effectively in improving product quality and increasing production. Currently SEH is the largest supplier of silicon materials in Japan.Though much technical progress was achieved especially in the polycrystal and CZ operations during the joint venture period, the joint venture with Dow Corning was dissolved in 1979. SEH was re-born as a 100% owned subsidiary of SEC.Along with the rapid progress of electronics industry, the requirement for high quality raw materials has become very severe these days. Electronics companies come to ask us to supply perfect crystals (defects free uniformly cloned and highly-nure crystals). The same thing can be said in wafer characteristics; cleanliness, flatness, and perfect surface and shape.SEH has been very keen to respond to these rapidly changing demands from customers by develoning and imnroving its technologies. Such efforts have broughtSEH high reputation and the growing share in bothdomesticand worldwidemarkets.We hope SEH will continue to supply high quality products to our customers, and our basic policy is to manufacture the best quality products at the lowest cost.
