Patent ID: 7642100

Claim:
A semiconductor processing method, comprising: processing a first substrate while detecting at least one value of a first processing parameter in a first apparatus; analyzing the first processing parameter, thereby yielding at least one first predicted parameter value; comparing the first predicted parameter value with a first pre-defined parameter value, thereby yielding at least one first comparison result; applying a first recipe corresponding to the first comparison result for processing a second substrate in the first apparatus with at least one second processing parameter value corresponding to the first recipe; analyzing the second processing parameter value, thereby yielding at least one second predicted parameter value; and determining whether a processing time of the first apparatus is longer than, or equal to, a pre-defined processing time, and wherein if the processing time of the first apparatus is longer than, or equal to the pre-defined processing time, the method further comprises; measuring the second substrate, thereby yielding at least one first measurement parameter value; comparing the first measurement parameter with the second pre-defined parameter, thereby yielding at least one third comparison result.
