Abstract

The present disclosure generally relates to determining a process condition in a semiconductor process using attribute-relative process conditions. An example is a method of forming an integrated circuit (IC). First and second historical process conditions are obtained. The first historical process conditions are of previous semiconductor processing corresponding to a target value of a process attribute for forming the IC, and the second historical process conditions are of previous semiconductor processing corresponding to variable values of the process attribute. Attribute-relative process conditions are calculated. Each attribute-relative process condition is based on the first historical process conditions and the second historical process conditions that correspond to a respective given value of the variable values. An average process condition is determined from a subset of the attribute-relative process conditions. A process condition of a subsequent semiconductor process is set based on the average process condition.
