Title: Semiconductor device
Inventor: KAMIYA MASAYUKI
IPC: H01L21/66
Filed: 1995-12-09
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor device which is applicable in a next generation and equipped with a deviation measuring structure which is easily operated. SOLUTION: Deviation measuring opposed electrodes 11 and 12 are formed on a conductor layer together with a required actual circuit 3. A deviation measuring dielectric pattern 21 is formed on an insulating layer (dielectric layer) located above or below the conductor layer together with the required actual circuit 3. The deviation measuring dielectric pattern 21 is so formed as to spread partially over the deviation measuring counter electrodes 11 and 12 (overlap or penetrate). If the conductor layer and the insulating layer deviate from each other in position, a part of the deviation measuring dielectric pattern overlapping the measuring opposed electrodes 11 and 12 is varied in area, so that a capacitor made up with the dielectric layer and the insulating layer is changed in capacitance, whereby a deviation between the conductor layer and the insulating layer can be measured.  Counter electrodes are enlarged, a correction circuit which hardly changes in electrostatic capacitance even if a deviation happens is added, and a change in electrostatic capacitance is also added, whereby a semiconductor device of this constitution can be enhanced in accuracy eliminating the effect of a change in film thickness and other manufacturing irregularities.
