Problems solved by technology

[0002] Photolithography (photo-lithography) has been widely used in the manufacturing process of various electronic products. Photolithography can be used to expose photoresist (PR) to form different patterns (pattern), but when the pattern of photoresist When the line space is small, the light transmittance is small, resulting in part of the photoresist not being exposed and connected together. Therefore, the pattern formed after photolithography cannot conform to the preset pattern, which greatly limits the electronic Product performance

Abstract

Provided are an exposure device and an exposure method. The exposure method comprises: using an exposure light source (110) to provide light to a photoresist layer (102), the light passing through a photomask (120) and a light transmitting substrate (101) to reach the photoresist layer (102); and using a reflective plate (130) to reflect the light, passing through the light transmitting substrate (101) and the photoresist layer (102), back to the photoresist layer (102). The exposure device and method can reduce the line spacing of a photoresist layer pattern.

Description

【Technical field】 [0001] The invention relates to the field of exposure technology, in particular to an exposure device and an exposure method. 【Background technique】 [0002] Photolithography (photo-lithography) has been widely used in the manufacturing process of various electronic products. Photolithography can be used to expose photoresist (PR) to form different patterns (pattern), but when the pattern of photoresist When the line space is small, the light transmittance is small, resulting in part of the photoresist not being exposed and connected together. Therefore, the pattern formed after photolithography cannot conform to the preset pattern, which greatly limits the electronic Product performance. [0003] In particular, in many current electronic devices, such as liquid crystal display devices, it is necessary to continuously reduce the pitch of patterns to improve the performance of the electronic devices. [0004] Therefore, it is necessary to provide an exposu...
