Patent ID: 8404075

Claim:
A method for bonding between at least two substrates comprising: providing a first substrate as one of the at least two substrates, the first substrate including a main face having an annular salient rim defining a bonding space and having an inner sidewall and an outer sidewall, the salient rim having at least one slit connecting the inner sidewall to the outer sidewall; providing a second substrate as one of the at least two substrates, the second substrate having a main face; depositing at least one drop of liquid adhesive on the main face of one of the two substrates, the volume of the drop of liquid adhesive deposited on one of the two substrates being greater than a volume of the bonding space; and bringing the two substrates into contact causing spreading of the liquid adhesive in the bonding space and flowing of an excess portion of the liquid adhesive through the slit formed in the rim.
