Patent ID: 7732241

Claim:
A manufacturing method of a microstructure comprising: forming a lower electrode on and in contact with a first region of an insulating surface; forming a sacrificial layer to cover the lower electrode; forming a first conductive film comprising a crystal to cover the sacrificial layer; growing the crystal to increase a grain size of the crystal; forming a second conductive film over the first conductive film; etching a portion of the first conductive film and a portion of the second conductive film to expose a portion of the sacrificial layer; and removing the sacrificial layer after etching the portion of the first conductive film and the portion of the second conductive film, wherein the first region is provided between a second region and a third region of the insulating surface, wherein the etched first conductive film is on and in contact with the second region of the insulating surface and the third region of the insulating surface, and wherein the etched first conductive film is provided over the lower electrode.
