Abstract

The invention provides a substrate processing apparatus including a lift pin assembly. The device is characterized in that the device includes a cavity main body forming an internal space for housing and processing a substrate, a heater unit which is configured in the internal space of the cavity main body and the upper side is provided with the substrate and a first lift pin slot part, a lift pin assembly having a lift pin unit which enables the substrate to move up and down while the heater unit which runs through upwards and downwards, when thermal deformation of the heater unit occurs, an upper part region being moved towards a horizontal direction according to the position of the first lift pin slot part, wherein the lift pin unit includes a top lift pin inserted into in the first lift pin slot part, a middle lift pin which can move relative to the top lift pin, a first connecting component connecting the upper lift pin with the middle lift pin, a lower lift pin which can move relative to the middle lift pin, and a second connecting component connecting the middle lift pin with the lower lift pin.

Description

technical field [0001] The present invention relates to a substrate processing apparatus, and more particularly, to a device which minimizes the size of a lift pin groove portion formed on a heater unit and also minimizes cracking between the lift pin and the heater unit. Substrate handling apparatus for lift pin assemblies. Background technique [0002] In general, in devices such as semiconductor manufacturing equipment and flat panel display device manufacturing equipment, lift pins are used to load or unload semiconductor wafers, glass substrates, etc. on or off a mounting table. [0003] In addition, in order to manufacture a semiconductor element or a liquid crystal display element, it is necessary to repeat several times the thin film deposition process of depositing a thin film of a dielectric material etc. on a wafer or glass (hereinafter referred to as a substrate), and to use a photosensitive material to expose or hide a selected part of the thin film. The etchin...
