ABSTRACT:
A semiconductor device having a measuring pattern that enhances measuring reliability and a method of measuring the semiconductor device using the measuring pattern. The semiconductor device includes a semiconductor substrate having a chip area in which an integrated circuit is formed, and a scribe area surrounding the chip area. The semiconductor device also includes a measuring pattern formed in the scribe area and having a surface sectional area to include a beam area in which measuring beams are projected, and a dummy pattern formed in the measuring pattern to reduce the surface sectional area of the measuring pattern. The surface sectional area of the dummy pattern occupies from approximately 5% to approximately 15% of a surface sectional area of the beam area.
