Title: Production of plane optical waveguide
Inventor: JUNG SUN-TAE
IPC: C23C16/40
Filed: 1998-07-08
Abstract: PROBLEM TO BE SOLVED: To produce a uniform plane optical waveguide by adding a surface planarization stage to minimize the difference in the thicknesses of films. SOLUTION: A lower coating layer is deposited on a substrate 40 and thereafter, the deposited surface is polished. After a core layer is deposited thereon, the deposited surface is polished. The surface polished core layer is patterned in order to form the optical waveguide. The upper coating layer is deposited on the optical waveguide formed by this patterning and thereafter the deposited surface is polished. The process of polishing the deposited film 402 on the substrate 400 by utilizing a polishing appliance 404, a polishing agent and chemicals is shown. White dots indicate the polishing agent and the black dots the chemicals. These dots indicate that the surface is made uniform after the polishing.  This mechanical polishing method causes the chemical reaction with the surface to be polished by using the chemicals, thereby changing the characteristics of the surface and promoting mechanical polishing efficiency. This process is frequently used for a mass production stage using a wafer and a semiconductor stage capable of making fine surface polishing.
