Abstract:
A glass substrate for a mask blank includes a rectangular-shaped main surface on which a film having a circuit pattern is to be formed. The main surface includes a quadrangular peripheral frame and a square-shaped center area defined by excluding the frame. The center area has a longitudinal length of 142 mm and a lateral length of 142 mm. A surface morphology of the center area is expressed by the following formulas. A flatness of a sum of compositing all of a kl P k (x)P l (y) is less than or equal to 20 nm when a sum of k and l is greater than or equal to 3 and less than or equal to 9. The flatness is less than or equal to 20 nm when a sum of k and l is greater than or equal to 10 and less than or equal to 30. { z  ( x , y ) = ∑ k = 0 N 1   ∑ l = 0 N 2   a kl  P k  ( x )  P l  ( y ) P k  ( x ) = 1 2 k  k !  d k dx k  [ ( x 2 - 1 ) k ] P l  ( y ) = 1 2 i  l !  d l dy l  [ ( y 2 - 1 ) l ]

Claim (Index 19):
