Abstract: A diffuser structure and a manufacturing method thereof are disclosed. The diffuser structure includes a substrate, a plurality of throughholes, and a glue layer. The throughholes are perpendicularly formed in the substrate. Each throughhole includes a gas-in part, a gas-out part, and a connecting part for connecting the gas-in part to the gas-out part. The glue layer is formed on a side wall of each gas-out part, and a thickness of the glue layer is between 1 ?m and 11 ?m. The present invention can solve a problem that particles are periodically generated after a periodic self-cleaning function is implemented in a plasma-enhanced chemical vapor deposition system.

Abstract: A shadow frame and a method of manufacturing the shadow frame are disclosed. The shadow frame is utilized in photoelectrical semiconductor manufacturing processes and is utilized for fixing a glass substrate by combing with a support base used to carry the glass substrate. The shadow frame has a plurality of frame components and welding parts, and the frame components are adjoined at the welding parts to form the shadow frame. The provided shadow frame and its manufacturing method are capable of improving the utility rate of the substrate used to manufacture the shadow frame, avoiding a waste of the substrate, and thereby capable of reducing the manufacturing cost.
