摘要: 本发明涉及用于使第一固体衬底(1)与含有第一材料的第二固体衬底(2)粘合的方法,该方法通过下面的步骤,尤其是下面的顺序进行:-在第二固体衬底(2)上形成或施加含有第二材料的功能层(5),-使第一固体衬底(1)与第二固体衬底(2)在功能层(5)上接触,-将固体衬底(1、2)一起压制用于在第一和第二固体衬底(1、2)之间形成永久粘合,该粘合通过第一材料与第二材料的固体扩散和/或相变至少部分地得到增强,其中在功能层(5)上产生体积增加。在粘合过程中,没有或仅仅稍微超出了第一材料对第二材料的溶解度极限,从而尽可能避免金属间相的沉积并与此相反地形成混合晶体。第一材料可以是铜,而第二材料可以是锡。
