Abstract:
A method of fabricating a component for use in a watch includes a step of depositing a first thin film on a wafer wherein the first thin film is adapted to allow light reflected away from the wafer to be indicative of a first color characteristic. The step of depositing the first thin film is performed by using a plasma-enhanced chemical vapor deposition process or a low pressure chemical vapor deposition process. The method may further include a step of fabricating a second color characteristic, including defining a pattern on the first thin film using photolithography, and, processing a region within a boundary of the pattern so that the region is adapted to allow light reflected away from the wafer to be indicative of the second color characteristic. The step of processing the region within the boundary of the pattern includes depositing a metal or a ceramic material within the boundary of the pattern which is indicative of the second color characteristic. The step of processing the region within the boundary of the pattern may also include depositing a second thin film within the region within the boundary of the pattern.
