Claim Text:
1. A method for manufacturing an integrated MEMS device, comprising: (a) providing a device wafer and forming a patterned first sacrificial layer and a first structural layer on the device wafer sequentially; (b) providing a circuit wafer having at least a patterned first bonding layer thereon; (c) bonding the first bonding layer on the circuit wafer to the device wafer; (d) patterning the device wafer to form a patterned second structural layer and to expose a portion of the first sacrificial layer; and (e) removing the first sacrificial layer; wherein, between the step (a) and step (b), further comprising a step (a′): forming a patterned second bonding layer on the first structural layer; and in the step (c) further comprising a step of bonding the first bonding layer to the second bonding layer.
