Embodiment Construction

[0018] Please also refer to Figure 3 to Figure 7 , is the flow process of the mold core manufacturing method of the present invention, and it comprises the following steps:

[0019] A metal substrate 510 is provided, wherein the material of the metal substrate 510 can be nickel-based alloy, copper-based alloy, chromium-based alloy, etc., and its shape is rectangular. A photoresist layer 400 is evenly coated on the metal substrate 510, such as image 3 shown. Wherein, the coated photoresist is an organic photoresist material, and a positive photoresist or a negative photoresist can be used. This embodiment adopts polymethyl methacrylate (Poly Methyl Meth Acrylate, PMMA). The method for coating the photoresist layer 400 is a spin coating method, and a spray coating method may also be used.

[0020] The exposure, development and etching steps are performed using a pre-designed mask 600 . The photomask 600 is aligned with the metal substrate 510, and an exposure step is perf...

Abstract

A process for preparing the template includes providing a metal substrate, coating a photoresist layer, exposing by a mask, developing, wet etching, electroforming between the metal substrate and residual photoresist layer, and stripping the residual photoresist layer.

Description

【Technical field】 [0001] The invention relates to a method for manufacturing mold cores. 【Background technique】 [0002] The mold core has a wide range of uses, and the products made from it can be used in the fields of information, electronics, biology, medical treatment, and optoelectronics. With the development of science and technology, the requirements for machining precision have increased, especially the emergence of X-ray profound precision electroforming molding (Lithographie GalVanoformung Abformung, LIGA) technology, which has made the manufacturing of mold cores from traditional machining to Micro and Nano Era. [0003] The high-precision microstructure mold core is manufactured using the electroforming process in LIGA technology. At present, there are mainly two ways to manufacture mold cores by electroforming. One is that the base material is made of non-metallic material, and a metal film is coated on the developed photoresist and the surface of the base ma...
