Abstract:
A method for manufacturing a three-dimensional structure comprising supplying a stack comprising, stacked in a vertical direction, a support substrate, a sacrificial layer, a layer of interest having a sidewall and a tensor layer having a sidewall, the tensor layer having a residual stress. The method also comprises removing a removal portion of the sacrificial layer, while retaining a remaining portion of the sacrificial layer underlying the layer of interest. The removal portion is located in line with a lateral portion of the layer of interest extending from the entire sidewall of the layer of interest. The residual stress of the tensor layer is configured to cause bending of the layer of interest during the step of removing the removal portion.
