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 6):
A test key layout, comprising multiple test keys, wherein each said test key comprises:\n an operating voltage line; a grounding voltage line at one side of said operating voltage line and spaced apart from said operating voltage line in a first direction; a first testing electrode on said operating voltage line and said grounding voltage line and electrically connecting with at least one of said operating voltage line and said grounding voltage line; and a second testing electrode on said operating voltage line and said grounding voltage line and electrically connecting with at least one of said operating voltage line and said grounding voltage line; wherein the pattern of said test keys is defined by an overlapping portion of one layout pattern from first exposure process and one layout pattern from second exposure process, and the length of said first testing electrode on each said test key is decreased sequentially in said first direction in order of said test keys, and the length of said second testing electrode on each said test key is increased sequentially in said first direction in order of said test keys.
