Abstract:
A method of forming a bond between members of a Micro-Electro-Mechanical System (MEMS), wherein the members each have mating surfaces at which the bond may be formed, the method comprising:depositing a first layer of mating material on a first mating surface; depositing a first layer of bonding material on the first layer of mating material, wherein the first layer of bonding material is selected from the group consisting of gold and tin; depositing a second layer of mating material on a second mating surface; depositing a second layer of bonding material on the second layer of mating material, wherein the second layer of bonding material is selected from the group consisting of indium and lead; and pressing the first mating surface and the second mating surface together, thereby pressing the first layer of bonding material to the second layer of bonding material, thereby forming an alloy to serve as the bond between the mating surfaces of the members of the MEMS.
