Abstract: PURPOSE:To form a poly Si pattern with high precision on a substratum provided with a step-difference by a method wherein, after poly Si is stuck on the substratum provided with a step-difference, and oxygen ion is selectively implanted into the poly Si, heat treatment is performed. CONSTITUTION:On an interlayer insulating film 6, a second layer poly Si 8 is stuck, and thereon a resist pattern 9 as a mask is formed.
