发明名称 Method for producing contact between two circuit layers separated by an insulating layer
摘要 The invention relates to the methods which make it possible to establish contacts between two conductive layers separated by an insulating layer.It consists in pressing the complex (101) formed by these three layers between a sonotrode (105) excited by ultrasound perpendicular to the plane of the complex and an anvil (106) whose face in contact with the complex has protruding ridges (107). Under the effect of the pressure and the ultrasound, the ridges deform the complex and make the insulating layer flow. When the conductive layers come into contact, after contraction of the insulating layer, they become welded to one another under the effect of the ultrasound.It makes it possible to obtain, at low cost, completely ohmic contacts between these two conductive layers.
