Patent ID: 7206655

Claim:
A system for acquiring semiconductor process status information, comprising: an equipment server for sending a start command according to a first protocol; a computer system server connected to the equipment server for converting the start command from the first protocol to a second protocol and outputting the converted start command; a protocol converter connected to the computer system server for converting the start command from the second protocol to a third protocol and outputting the converted command according to the third protocol; an AD/DA module connected to the protocol converter for converting the start command from the third protocol to an analog signal and outputting the converted command; an external sensor connected to the AD/DA module for acquiring semiconductor process status information as initiated by the start command; wherein the AD/DA module converts the semiconductor process status information from analog signals to the third protocol and outputs the converted information to the protocol converter; the protocol converter converts the semiconductor process status information from the third protocol to the second protocol and outputs the converted information to the computer system server; and the computer system server outputs the converted information to the equipment server.
