Abstract:
A set of test key layout including multiple test keys and method of monitoring layout pattern misalignments using the test keys is provided. Each test key is composed of a testing electrode, an operating voltage (V dd ) line and a grounding voltage (V ss ) line, wherein the patterns of test keys are defined by an overlapped portion of a first exposure pattern and a second exposure pattern, and the position of testing electrode is shifted sequentially in one direction in order of the test keys.

Claim (Index 11):
A method of monitoring layout pattern misalignments, comprising:\n providing a set of test keys, wherein each said test key comprises an operating voltage line spaced apart in a first direction; forming a testing electrode electrically connecting with at least one said operating voltage line and said grounding voltage line on each said test key, wherein the lay out pattern of said testing electrodes is defined by an overlapping portion of one layout pattern from first exposure process and one layout pattern from second exposure process, and the positions of said testing electrode on each said test key is shifted sequentially in said first direction in order of said test keys; and measuring the resistance of each said test key and determine the misalignment offset of said layout pattern from first exposure process and said layout pattern from second exposure process.
