METHOD FOR ANNEALING BONDING WAFERS
The invention relates to a method for annealing of at least two wafers bonded via low-temperature direct bonding comprising heating the bonded wafers up to a first annealing temperature in the range of 100° C. to 500° C., preferably 150° C. to 400° C., even more preferred 150° C. to 200° C., holding the first annealing temperature in a range of 1 to 4 hours, preferably 1 to 3 hours, cooling down the bonded wafers to room temperature, re-heating the bonded wafers to a second annealing temperature in the range of 100° C. to 500° C., preferably 150° C. to 400° C., even more preferred 150° C. to 200° C., and cooling down the bonded wafers to room temperature.
