Abstract:
A method for fabricating an electronic component which component had an asymmetric resist pattern formed on the component during the manufacturing process and wherein the electronic component substrate is coated with a photoresist and exposed to light traveling through a mask having the desired circuit pattern thereon, the method comprising:coating the electronic component substrate with a photoresist material;positioning the substrate on a holding device;positioning a mask so that light impinging on one surface of the mask travels through the mask and impinges on the coated substrate to form an image of the mask design in the photoresist material, the mask comprising:a mask substrate which allows light to pass therethrough;a light shielding material on the mask substrate in the form of lines and other shapes forming a pattern which defines the resist pattern to be formed in the resist on the coated substrate; andphase shifter means on the mask substrate continuously on at least at one side of the light shielding means so that when light passes through the mask the phase of light on the photoresist is different on each side of the light shielding means by other than 0.degree. or 180.degree., or multiples thereof;exposing the mask to light;developing the exposed substrate to form the desired resist forming the desired electronic component.
