Si/SiGe epiwafers at ATMI

摘要

There have been some interesting developments in the epitaxial growth of SiGe-type materials since the last article. The market has been somewhat inconspicuous with few announcements of actual purchases of reactors by the handful of major suppliers. Nevertheless, behind the scenes interest is high and it's just that it can seldom be reported. One development in commercial epiwafers which stands Out is the changes at ATMI. It has been steadily reducing certain of its semiconductor materials businesses. Previously it was one of the more diverse players in the business but having already exited the GaAs epiwafer sector and most recently the Ill-nitrides, it is left with Si and SiGe merchant epi. It is an open secret that ATMI wishes to focus on other materials for the semiconductor industry and is looking to find a similar good home for the remaining epi business.
