Multilayer structure with controlled internal stresses and making same
First Claim
1. Method for producing a multilayer structure having a defined geometrical orientation from at least a first main layer and a second main layer comprising the steps of:
- (a) providing the first main layer with a first stress adaptation layer and providing at least a second stress adaptation layer between the first stress adaptation layer and the second main layer;
(b) wherein said first and second main layer is assembled via the stress adaptation layers such that stress is exerted on said main layers to cause the multilayer structure to assume a predetermined geometrical orientation selecting from the group consisting of;
convex, flat or concave geometry based upon the thickness, number and adherence of the adaptation layers.

Abstract
A multilayer structure with controlled internal stresses comprising, in this order, a first main layer (110a), at least a first constraint adaptation layer (130) in contact with the first main layer, at least a second stress adaptation layer (120) put into contact by adhesion with said first stress adaptation layer, and a second main layer (110b) in contact with the second stress adaptation layer, the first and second stress adaptation layers having contact stresses with the first and second main layers.
Application to the realization of electronic circuits and membrane devices.
