Embodiments of the invention provide methods for mounting and dicing a
double bumped wafer. For one embodiment, the thickness of the adhesive
layer of a dicing tape is greater than the height of the bumps to which
it is applied, such that the adhesive layer conforms to the bumps and
distributes the pressure of a mounting roller more evenly. For one
embodiment, the dicing tape has an adhesive layer approximately twice the
thickness of the wafer bump to which it is applied. For one embodiment, a
radiation sensitive adhesive is used that has a pre-radiation adhesive
strength of approximately 200 grams/25 mm.sup.2 and a post-radiation
adhesive strength of approximately 2 grams/25 mm.sup.2. For one
embodiment, a dual blade dicing process is employed that cuts into only a
portion of the adhesive layer of the dicing tape in order to reduce
adhesive blade loading.
