Patent ID: 6942750

Claim:
A method of low-temperature bonding an apparatus, said method comprising: providing a first substrate having a first surface, said first surface having a first portion of a MEMS device formed thereon; providing a second substrate having a second surface, said second surface having a second portion of said MEMS device formed thereon; applying photosensitive benzocyclobutene to said first surface of said first substrate in a predetermined pattern to define a bonding layer, an area of said bonding layer being less than an area of said first surface; positioning said second substrate in contact with said bonding layer on said first substrate to create a bond between said first substrate and said second substrate at said bonding layer at a temperature between about 50° C. and about 300° C. to form a bonded unit, said positioning of said second substrate in contact with said first substrate further joins said first portion of said MEMS device to said second portion of said MEMS device; and etching said bonded unit to further form said MEMS device.
