Title:
SEMICONDUCTOR PROCESS CHAMBER, SEMICONDUCTOR PROCESS APPARATUS, AND SEMICONDUCTOR PROCESS METHOD
Document Type and Number:
WIPO Patent Application WO/2023/030214
Kind Code:
A1
Abstract:
Provided are a semiconductor process chamber, a semiconductor process apparatus, and a semiconductor process method. The chamber comprises a reaction chamber (100) and a transfer chamber (200) located below the reaction chamber (100), wherein the reaction chamber (100) is in communication with the transfer chamber (200) through a bottom opening; a base (300) is arranged in the semiconductor process chamber; a lifting shaft (520) is connected to the bottom of the base (300), so as to move up and down between the reaction chamber (100) and the transfer chamber (200) through the bottom opening; an elastic annular sealing structure (400) is arranged below the base (300) and around the lifting shaft (520) of the base (300); during the base (300) descending to the transfer chamber (200), the base (300) can press down the annular sealing structure (400), such that the annular sealing structure is compressed; and when the base (300) rises to the reaction chamber (100), and pressure applied to the annular sealing structure (400) is relieved, the annular sealing structure (400) elongates under the action of its own elastic force until the annular sealing structure abuts against a bottom wall of the reaction chamber (100), so as to seal the bottom opening. The pressure control effect of the reaction chamber (100) is improved, a process effect is improved, a wafer transfer time is shortened, and the film forming efficiency of a semiconductor process is increased.
