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 20):
A mask blank comprising:\n a glass substrate including a rectangular-shaped main surface; and a film formed on the rectangular-shaped main surface of the glass substrate, a circuit pattern being to be formed on the film; wherein the main surface of the film on the opposite side of the glass substrate is rectangular-shaped and comprises a quadrangular peripheral frame and a square-shaped center area defined by excluding the quadrangular peripheral frame from the rectangular-shaped main surface, wherein the square-shaped center area has a longitudinal length of 142 mm and a lateral length of 142 mm, and wherein a surface morphology of the square-shaped center area z(x, y) is expressed by { z \ue8a0 ( x , y ) = \u2211 k = 0 N 1 \ue89e \ue89e \u2211 l = 0 N 2 \ue89e \ue89e a kl \ue89e P k \ue8a0 ( x ) \ue89e P l \ue8a0 ( y ) P k \ue8a0 ( x ) = 1 2 k \ue89e k ! \ue89e d k dx k \ue8a0 [ ( x 2 - 1 ) k ] P l \ue8a0 ( y ) = 1 2 i \ue89e l ! \ue89e d l dy l \ue8a0 [ ( y 2 - 1 ) l ] \u2003 wherein a flatness of a sum of combinations of a kl P k (x)P l (y), where k and l are each an integer and a sum of k and l is from 3 to 30, is 22 nm or less.
