Abstract:
A semiconductor manufacturing device for baking a wafer, comprising:a chamber;a heating portion provided in said chamber, said wafer being placed thereon;a cover comprising an inner wall face opposite to a main surface of said wafer, an inlet/outlet provided opposite the main surface of said wafer, and a member having a ventilation hole;wherein the distance between the main surface of said wafer placed on said heating portion and said inner wall face is fixed;wherein said cover defines a first gas path including said inlet/outlet,wherein said cover defines a second gas path adjacent at least a portion of said first gas path,wherein said member is provided within said first gas path such that a distance between said member and the main surface of said wafer is substantially identical to the distance between the inner wall face of said cover and the main surface of said wafer.
