Embodiment Construction

[0035] figure 1 and figure 2 Shown is a plan view and a partial section enlarged view of the present invention. The present invention is a metal-plastic multi-layer photomask 1, which is mainly used in the manufacturing process of optoelectronic products. On the substrate to be processed, a film with a specific pattern is deposited on a substrate to be processed. The substrate is a material containing silicon or glass. , such as the substrate of a liquid crystal screen. The multi-layer photomask 1 is a sheet-shaped frame, and at least one pattern unit 11 is formed through the frame. The contour shape of the pattern unit 11 is the shape corresponding to the aforementioned specific pattern, and the specific pattern depends on the manufacturer's requirements. It is convenient to deposit the corresponding thin film on the substrate in the manufacturing process of optoelectronic products.

[0036] The main improvement of the present invention is to design the multi-layer photom...

Abstract

The invention discloses a metallic-plastic multi-layered photomask and a manufacturing method thereof, which are mainly used in the manufacturing technology of photoelectric products. The multi-layered photomask is composed of a metallic photomask and a resin layer formed on the surface of the metallic photomask, wherein the resin layer is softer than the metallic photomask. The manufacturing method of the multi-layered photomask comprises the following steps: performing thermal debinding on the metallic photomask, further coating the surface of the metallic photomask with a resin layer by means of electrophoresis treatment, and then, orderly performing the operations of cleaning, drying and molding, thus forming the multi-layered photomask. Due to the resin layer, the multi-layered photomask provided by the invention can achieve the effects of buffering and wear resistance in the clamping fixation work of the manufacturing technology, so that the replacement cycle and service life of the multi-layered photomask are prolonged, and the quality of the manufacturing technology is also improved.

Description

technical field [0001] The present invention relates to the production technology of optoelectronic products, in particular to a metal-plastic multi-layer photomask which can be used in the production and manufacturing process of optoelectronic products, which can prolong the replacement cycle of such photomasks, improve the quality of production, and reduce production costs. its method of manufacture. Background technique [0002] In the current optoelectronic products, such as the panel of the liquid crystal screen, some thin films of different materials are deposited on the glass substrate during the manufacturing process using a photomask, and the process includes but not limited to coating, exposure, etching, development, cleaning , Baking and other steps, use multiple different masks to operate in sequence, and plan the designed structure layer by layer. Among the above-mentioned mask costs, the mask made of quartz material is the highest. This kind of mask can meet t...
