Patent ID: 11876001
Assignee: NEXCHIP SEMICONDUCTOR CORPORATION
Field: Semiconductors (Electrical engineering)
Classification: CPC H  C | IPC C  H

Claim 0:
1. A method for manufacturing a semiconductor layer, comprising:
placing a first wafer in a cavity, to form a metal film on the first wafer; wherein, before forming the metal film, a temperature inside the cavity is a first temperature;
transferring the first wafer on which the metal film has been formed out of the cavity; wherein, a temperature in the cavity is a second temperature, and the second temperature is greater than the first temperature;
introducing an inert gas into the cavity to cool the cavity, such that the temperature in the cavity is equal to the first temperature;
after the temperature in the cavity is equal to the first temperature, placing a second wafer in the cavity to form the metal film on the second wafer.
