Patent ID: 7022249

Claim:
A method for manufacturing an optical micro-mirror including a fixed part and a moveable part connected to the fixed part by an articulation mechanism, the moveable part including a reflector, the method comprising: a) forming a stack formed of a mechanical substrate, a sacrificial layer of a specific thickness of thermal oxidation material as a first layer, and an assembly for forming the moveable part and including at least one layer of material as a second layer; b) forming the articulation mechanism; c) forming the moveable part by etching of at least the second layer of material to obtain at least one pattern; and d) removing at least in part the sacrificial layer for clearing the moveable part that is then connected to a rest of the micro-mirror corresponding to the fixed part using the articulation mechanism, wherein: the step a) of forming the stack comprises transferring onto the mechanical substrate the second layer, the substrate and/or the second layer including on their faces to be transferred a thermal oxidation layer that will form the first layer after the transferring.
