Abstract

The invention provides a movable adjusting drive unit for optical elements, comprising: a main body; a first flexible soleplate and a second flexible soleplate which are respectively arranged at the two ends of the main body; a first flexible soleplate fixed block and a second flexible soleplate fixed block which are fixed on the sides of the two ends of the main body to limit the first flexible soleplate and the second flexible soleplate to move up and down; a first adjusting screw and a second screw which are respectively connected with the first and second flexible soleplate through the screwed holes on the main body; a driving mechanism which is fixed between the first flexible soleplate and the second flexible soleplate; and a deformation block which is connected with one end of the main body. The invention has the advantages of low hysteresis quality, strong load capacity, good repeatability and stability, high precision (which can reach to a nanometer level ), convenient maintenance and the like, and has the advantages of large distance of travel, simple structure, low processing difficulty and the like.

Description

technical field [0001] The invention relates to the technical field of semiconductor manufacturing, and in particular to a movable optical element adjustment driving device applied in exposure equipment. Background technique [0002] With the continuous development of semiconductor technology, the manufacturing process of semiconductor devices has higher and higher requirements for precision. For example, in the lithography process, the projection optical system in the exposure equipment of advanced lithography machine needs smaller and smaller wave phase difference and distortion. , and at the same time, in the exposure equipment of this projection optical system, the changes of phase difference and distortion caused by various environments and other factors can be easily compensated in real time. In order to solve this type of problem, it is generally compensated by setting one or several lenses whose position or shape can be adjusted. [0003] In the prior art, there are...
