Abstract: An objective is to provide a film formation method with which a layer having reduced defects, a die obtained by the film formation method, and a method of manufacturing the die. Free carbons increase in the case of reducing hydrogen gas as a carrier gas, so that concave portions are generated and increased during the molding transfer surface process. It was commonly known that hydrogen gas employed for the thermal CVD was set to 2 moles, but it was found out that generation of concave portions was possible to be largely inhibited by setting hydrogen gas to at least 3 moles. However, a level of up to 8 moles is preferable in view of practical use, since dilution of the total raw material gas causes a decline of reaction speed in the case of too much increase of hydrogen gas, resulting in the low speed of film formation.

Abstract: A mesh (M) having an ellipsoid shape or a shape close to the ellipsoid shape is attached to an electrode (EL1) among electrodes (EL1 to ELn). Voltages of the later-stage electrodes (EL2 to ELn) are appropriately set. With this arrangement, a local negative spherical aberration generated by the mesh (M) is cancelled out with a positive spherical aberration. This optimizes an electric field distribution. As a result, this realizes an electrostatic lens whose acceptance angle is extended to about ±60°.
