Patent ID: 7935573

Claim:
A method for fabricating an electronic device comprising the steps of: forming a first sealing structure on one primary surface of a first substrate, enclosing a predetermined region of said one primary surface of the first substrate, where an electronic circuit element is formed; cutting the upper portion of the first sealing structure with a cutting tool; forming a second sealing structure on a second substrate, corresponding to the first sealing structure; cutting the upper portion of the second sealing structure with a cutting tool; forming a semi-cured adhesion layer on the side surface of one of the first sealing structure and the second sealing structure; causing the first sealing structure and the second sealing structure adhered with each other, and performing thermal processing with said one of the first sealing structure and the second sealing structure positioned upper of the other of the first sealing structure and the second sealing structure so as to melt the adhesion layer and cause the adhesion layer to arrive at the side surface of said other of the first sealing structure and the second sealing structure; and performing thermal processing after the adhesion layer has been cured to bond the first sealing structure and the second sealing structure by solid phase diffusion bonding.
