Methods and devices for adhesively bonding a sensor die to a substrate are described. In some cases, a sensor assembly may include a pressure sensor die mounted to a substrate with an adhesive. The pressure sensor die may be fabricated to include a back-side having one or more adhesion features (e.g. recesses or indentations), which increase the surface area of the pressure sensor die that is in contact with the adhesive, to thereby increase the adhesion force therebetween. In some cases, the one or more adhesion features may define a non-planar interface between the pressure sensor die and the adhesive which, in some instances, may reduce the formation and/or propagation of cracks in the adhesive, which also may help increase the adhesion force therebetween.
