# Carl Frosch

> Carl John Frosch was a Bell Labs researcher. With Lincoln Derick, Frosch discovered that silicon could be protectively coated by silicon dioxide by the right exposure to oxygen when hot, and patented the method. Such protective coating overcame a problem of surface states found in active silicon circuit elements. The discovery also revealed the potential for the process of silicon etching.
