REMOTE MONITORING SYSTEM FOR POLISHING END POINT DETECTION UNITS
First Claim
1. A remote monitoring system, comprising:
- a plurality of polishing end point detection units each configured to detect a polishing end point of a substrate; and
a host computer coupled to the polishing end point detection units via a network, the host computer including a memory configured to store polishing end point detection data sent from the polishing end point detection units and a display screen configured to display the polishing end point detection data,wherein the host computer is configured to send a new polishing end point detection recipe to at least one polishing end point detection unit selected from the polishing end point detection units to rewrite a polishing end point detection recipe of the least one polishing end point detection unit.

Abstract
The present invention relates to a remote monitoring system for polishing end point detection units mounted to polishing apparatuses for polishing wafers, such as substrates. The remote monitoring system includes: polishing end point detection units each configured to detect a polishing end point of a substrate; and a host computer coupled to the polishing end point detection units via a network. The host computer includes a memory configured to store polishing end point detection data sent from the polishing end point detection units and a display screen configured to display the polishing end point detection data. The host computer is configured to send a new polishing end point detection recipe to at least one polishing end point detection unit selected from the polishing end point detection units to rewrite a polishing end point detection recipe of the least one polishing end point detection unit.
