| 摘要 | Embodiments describing a method of forming a multi-layered keycap structure are disclosed herein. The method includes forming a first polymer layer on a second polymer layer, wherein the first polymer layer includes a first color and the second polymer layer includes a second color, and coupling the first polymer layer and second polymer layer to a substrate layer such that the first polymer layer is closer to the substrate than the second polymer layer. The method may further include forming a third polymer layer on the second polymer layer; and etching the multi-layered keycap structure to form an opening having a bottom surface that exposes at least one of the first or second color. | ||||||
