Method for selectively treating surfaces

摘要

A method of treating a surface includes providing an object and applying a masking layer to a target surface area of the object. A sacrificial material is applied to a non-target surface area of the object. The method also includes removing the masking layer from the target surface area. The target surface area is exposed to a substance that etches or coats the target surface area. The sacrificial material from the non-target surface area of the object is removed, leaving the target surface area of the object etched or coated by the substance while the non-target surface area is not etched or coated by the substance.

1. A method of treating a surface comprising:
providing an object having at least one planar face; applying a masking layer to a target surface area of the object, wherein the target surface area includes at least a portion of the planar face, and wherein applying the masking layer to the target surface area is a dry process; applying a sacrificial material to a non-target surface area of the object while the masking layer is still applied to the target surface area of the object; removing the masking layer from the target surface area; exposing the target surface area to a substance that etches the target surface area of the object; and removing the sacrificial material from the non-target surface area of the object and leaving the target surface area of the object etched by the substance while the non-target surface area is not etched by the substance, wherein the object includes an optical eyepiece to be coupled to a head mounted display (“HMD”) and the masking layer includes an adhesive film for bonding to the target surface area.
