Abstract

Abstract A first object, which comprises organic material, is bonded to a second object by a method whereby both objects are provided with complementary optically smooth surfaces, subsequent to which these surfaces are brought into substantial contact with one another, consequent upon which spontaneous atomic bonds are formed between atoms of the two objects. The strength of the atomic bonds thus formed can be increased by subsequently heating the region of contact of the two surfaces.

Claims Analysis

Total Claims: 20
Claim 1
Independent Claim 84 words
A method of bonding a first object having a surface consisting essentially of an organic material to a second object, said method comprising polishing said surface consisting essentially of an organic material and a surface of said second object so as to form optically smooth complementary surfaces of RMS roughness of less than 2nm and then bringing said surfaces into contact with each other thereby spontaneously forming atomic bonds between atoms of said surfaces and causing said surfaces to bond one to the other.
Claim 2
Independent Claim 84 words
A method of bonding a first object having a surface consisting essentially of an organic material to a second object, said method comprising polishing said surface consisting essentially of an organic material and a surface of said second object so as to form optically smooth complementary surfaces of RMS roughness of less than 2nm and then bringing said surfaces into contact with each other thereby spontaneously forming atomic bonds between atoms of said surfaces and causing said surfaces to bond one to the other.
