Patent ID: 11901206
Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A system, comprising:
a processing tool configured to process a semiconductor workpiece;
a first pressurized load port configured to receive the semiconductor workpiece from the processing tool, wherein an air pressure in the first pressurized load port is equalized with a set pressure level;
a second pressurized load port configured to receive the semiconductor workpiece from the first pressurized load port, wherein the second pressurized load port is set at the set pressure level when receiving the semiconductor workpiece from the first pressurized load port and thereafter set to an external air pressure; and
an inspection tool configured to receive the semiconductor workpiece from the second pressurized load port, wherein the inspection tool is configured to inspect the semiconductor workpiece for defects from processing by the processing tool.
