It is especially useful for etching crystalline silicon surfaces and also covers a method of producing optical and semiconductor devices. In the past, chemical etching was used to etch various materials. A number of processes and apparatus have been used for this purpose. For instance, in U.S. Pat. No. 3,856,432, etching of silicon is accomplished by using a gaseous mixture of fluorine and ozone. Also, in U.S. Pat. No. 3,907,505, etching of silicon is accomplished by using a gaseous mixture of halogen acid and ozone. The present invention provides a novel apparatus for washing and etching using plasma. The present invention also provides a novel method of producing optical and semiconductor devices from crystalline silicon. One object of the present invention is to provide a system and
