Patent ID: 8334533

Claim:
A semiconductor device comprising: a circuit area in which a semiconductor integrated circuit is formed; and a monitor area having at least two monitor layers simultaneously formed with at least two layers each composing said semiconductor integrated circuit, the at least two monitor layers including a first monitor layer and a second monitor layer, the first monitor layer and the second monitor layer being stacked, wherein the first monitor layer includes at least five first monitor patterns of substantially the same shape and are disposed at a first pitch between each other, wherein the second monitor layer includes at least five second monitor patterns of substantially the same shape and are disposed at a second pitch between each other, wherein all of the first monitor patterns and the second monitor patterns extend in a first direction, wherein the first monitor patterns and the second monitor patterns are respectively coupled via grooves which extend in the first direction and are embedded with conductive film, wherein the semiconductor integrated circuit, the five first monitor patterns, and the five second monitor patterns are provided in a chip which has been chipped by dicing a semiconductor wafer, wherein the grooves comprises a linear first side extending in the first direction and a linear second side extending parallel to the first side in the first direction, wherein the five first monitor patterns and the five second monitor patterns are not electrically connected to a pad, wherein the monitor area includes a first monitor area and a second monitor area, and the directions in which monitor patterns extend differs between the first monitor area and the second monitor area, and wherein the directions in which said monitor patterns extend in the first monitor area and the second monitor area are perpendicular to each other, and both of the directions are parallel to a surface of a substrate above which the first monitor patterns and the second monitor patterns are formed.
