Abstract
Description
technical field
[0001] The invention relates to the technical field of semiconductor equipment manufacturing, in particular to a heating chamber and semiconductor processing equipment. Background technique
[0002] Physical vapor deposition (Physical Vapor Deposition, hereinafter referred to as PVD) technology is a commonly used processing technology in the field of microelectronics, for example, it is used to process copper interconnect layers in integrated circuits. The production of copper interconnection layer mainly includes the steps of degassing, pre-cleaning, Ta(N) deposition, and Cu deposition. The degassing step is to remove water vapor and other volatile impurities on the substrate and other processed workpieces. When implementing the degassing step, it is necessary to put the processed workpiece such as the substrate into the heating chamber and heat it to a certain temperature of 230-350°C.
