Abstract

The invention discloses a method of forming a conductive totem by using a gravure printing mode. A conductive layer is firstly formed on a substrate; the gravure printing mode is then used to form a shielding protection totem on the conductive layer; and finally, the conductive layer is etched, and the conductive layer forms a conductive totem corresponding to the shielding protection totem. With the help of the gravure printing mode, the shielding protection totem can be formed directly without processes such as yellow light exposure and development, and thus, the process complexity can be reduced to improve the process speed, and the stock use is reduced to reduce the cost.

Description

technical field [0001] The invention relates to a method for forming a conductive totem, in particular to a method for forming a conductive totem by gravure printing. Background technique [0002] With the advancement of science and technology, technology products are developing in the direction of thinner, thinner and smaller. Therefore, integrated circuits are widely used in various electronic products. In the manufacturing process, it is necessary to make extremely fine-sized circuits on the substrate. When patterning, it is mainly achieved by etching lithography technology. [0003] For example, "A method for preparing a circuit board with a patterned conductive layer" in Taiwan Patent Announcement No. I459875, the manufacturing method is to first set a conductive layer on a substrate, and then set a photolithographic layer on the conductive layer. Then, a photomask layer with a predetermined pattern is set on the photoresist layer, and a radiation light is applied to t...
