Abstract:
Described examples include a device including a semiconductor die having a first surface with bond pads and an opposite second surface attached to a substrate by an adhesive layer covering at least a portion of the surface area of the second surface. The adhesive layer includes first zones composed of a first polymeric compound and adding up to a first portion of the surface area, and second zones composed of a second polymeric compound and adding up to a second portion of the surface area, the first zones and the second zones being contiguous. The first polymeric compound has a first modulus and the second polymeric compound has a second modulus greater than the first modulus.
