The minimum height of the bottoms of recesses as measured from the lower side of the coating film is expressed by L, and two horizontal lines are drawn at the upper and lower levels of ±10 nm based on the position (H+L)/2 as a center. When the range between two points where the lower-level horizontal line intersects the cross-section profile curve includes one or more points where the upper-level horizontal line intersects the profile curve, then the number of the protrusions present in this range is taken as 1. The number of the protrusions per unit length is thus determined as the linear density of the protrusions. COPYRIGHT: (C)2010,JPO&INPIT
