Abstract:
1. A manufacturing method of a microstructure, comprising the steps of: forming a first layer over an insulating substrate; forming a first resist mask over the first layer by using a photomask; processing the first layer by using the first resist mask to form a first sacrificial layer; forming a second layer over the first sacrificial layer; forming a second resist mask over the second layer by using the photomask; conducting a process for changing an external dimension of the second resist mask; processing the second layer by using the second resist mask to form a second sacrificial layer; forming an insulating layer so as to cover the second sacrificial layer; forming openings in the insulating layer; and introducing an etchant into the openings so that the first sacrificial layer and the second sacrificial layer are concurrently removed.
