Problems solved by technology

[0005] However, due to the limitation of the heat absorption performance of the material (usually steel) of the cavity 102 and the upper cover 101, the heat absorption efficiency of the cooling chamber is low, resulting in a slow cooling rate of the tray, which cannot meet the production capacity requirements of the equipment.

Abstract

The invention provides a cooling chamber and semiconductor processing equipment. The chamber wall of the cooling chamber is internally provided with a first cooling channel, and the cooling medium is piped into the first cooling channel so as to cool the chamber wall. Besides, the cooling chamber is internally provided with a bracket which is used for bearing a tray, and the tray is used for bearing a processed workpiece. Furthermore, a black oxide layer is formed on at least partial internal surface of the chamber wall of the cooling chamber. According to the cooling chamber, the cooling efficiency of the tray can be enhanced so as to enhance the productivity of equipment.

Description

technical field [0001] The invention relates to the field of semiconductor manufacturing, in particular to a cooling chamber and semiconductor processing equipment. Background technique [0002] Physical vapor deposition (PVD) technology is the most widely used type of thin film manufacturing technology in the semiconductor industry, and generally refers to the thin film preparation process that uses physical methods to prepare thin films. In the PVD process, the deposition of most thin films requires the base to cool or heat the wafer, and its efficiency plays a vital role in the quality of deposited thin films. [0003] After the high-temperature process is completed, the tray used to carry the wafer needs to be lowered to a lower temperature in a vacuum before it is passed out of the process chamber and exposed to the atmosphere to ensure the quality of the deposited film and It is convenient for the operator to operate. In order to reduce the tray to a reasonable tempe...
