Abstract

The invention relates to a mobile device of a photoetching machine wafer stage and a photoetching machine adopting the mobile device. The mobile device of the photoetching machine wafer stage comprises a supporting plate supporting the photoetching machine wafer stage, an air pocket arranged on one side of the supporting plate opposite to the wafer stage, an air cushion device arranged on the side of the supporting plate same to the side of the air pocket, an idle wheel arranged on the side of the supporting plate same to the side of the air pocket; the air pocket is aerated and supports the supporting plate and the photoetching machine wafer stage; when the photoetching machine wafer stage is moved, the air pocket opens the air cushion device while releasing the gas; an air cushion formed by the air cushion device supports the supporting plate and the silicon stage; the mobile device of the photoetching machine wafer stage utilizes the idler wheel to shift out the wafer stage or shift the wafer stage into the photoetching machine. The shift-in and shift-out process of the wafer stage of the photoetching machine adopting wafer stage mobile device is simpler, can ensure the accurate locating of the wafer stage and a supporting frame of the photoetching machine and can reduce the disturbance of the ground vibration on the wafer stage.

Description

technical field [0001] The invention relates to a silicon wafer stage moving device of a lithography machine and a lithography machine using the moving device. Background technique [0002] Photolithography is a very important process in the semiconductor manufacturing process. It is a process of sequentially transferring chip patterns on a series of reticles to corresponding layers of silicon wafers through exposure. It is considered to be the core step in large-scale integrated circuit manufacturing. . A series of complex and time-consuming photolithography processes in semiconductor manufacturing are mainly completed by corresponding photolithography machines. The development of lithography technology or the technological progress of lithography machines mainly revolves around the three major indicators of line width, overlay accuracy and productivity. [0003] In the stepper projection lithography machine, the main purpose of the silicon wafer stage is to provide a mot...
