Embodiment Construction

[0019] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0020] The present invention expects to provide an optical system for splicing double mercury lamps, which can accurately monitor and control the energy of the double light sources while increasing the illuminance on the substrate, and can realize switching between the working modes of the double lamps and single lamp.

[0021] figure 1 It is a schematic diagram of the overall structure of the double mercury lamp splicing exposure system involved in the present invention. Such as figure 1 As shown in , the double mercury lamp splicing exposure system is mainly composed of the following modules: light source 1, rectangular prism 2, small quartz rod 3, coupling lens group 4, large quartz rod 5, and relay lens group 6. Here, the small quartz rod 3 and the large quartz rod 5 are defined according to the relative size of their volumes. Such as ...

Abstract

The invention discloses a double-mercury lamp spliced exposure system for lithography equipment. The double-mercury lamp spliced exposure system comprises a first light source and a second light source used for simultaneously or respectively providing illuminating beams; a first dodging component and a second dodging component which respectively correspond to the first light source and the second light source, a coupling lens group used for improving the illumination uniformity of the exposure system, and an illuminating and dodging component used for dodging emergent light of the coupling lens group to illuminate an illumination surface.

Description

technical field [0001] The invention relates to the field of integrated circuit equipment manufacturing, in particular to a double mercury lamp splicing exposure system for photolithography equipment. Background technique [0002] The photolithography device is the main equipment for manufacturing integrated circuits. Its function is to sequentially image different mask patterns onto the precisely aligned positions on the substrate (such as semiconductor silicon wafer or LCD panel). However, this alignment position changes due to the physical and chemical changes experienced by successive patterns, so an alignment system is needed to ensure that the alignment position of the silicon wafer corresponding to the mask can be accurately aligned every time. As the number of electronic components per unit surface area of ​​the substrate increases and the size of electronic components becomes smaller and smaller, the precision requirements for integrated circuits are increasing. The...
