Epiwafer I am surprised to learn that epiwafer was a popular term right around 2000 2002 the exact time that my company started to use epi wafers I should pay more attention to ads I guess Anyway it quickly settled back to more normal terminology like epitaxial wafer looks like I guess another move is in order Hi I think it best to look at all those Google searches on the Talk page and see which spelling nomenclature adding the web book singular plural spellings that s four searches for each spelling has the most hits for the title of the article If you want I can do that and add them up Of course the company name will skew epiwafer so we can exclude that if you like We don t use plurals and book searches are generally more authoritative than web searches but feel free to provide more data Plurals are for the Google searches because obviously many of the mentions even in books are only in plural not singular so an exact phrase Google search i e in quotation marks will omit those mentions unless a plural form is searched I m fine with the fully spelled out version as long as all of the other spellings redirect to it therefore should probably also create a redirect for Epi wafer since that hyphenated form is sometimes used as well Yes good point s
