A conformal coating on a semiconductor die provides adhesion between the die and a support. No additional adhesive is necessary to affix the die on the support. The conformal coating protects the die during assembly, and serves to electrically insulate the die from electrically conductive parts that the die may contact. The conformal coating may be an organic polymer, such as a parylene, for example. Also, a method for adhering a die onto a support, which may optionally be another die, includes providing a coating of a conformal between the die and the support, and heating the coating between the die and the support. The conformal coating may be provided on a die attach area of a surface of the die, or on a die mount region of a surface of the support, or on both a die attach area of a surface of the die and on a die mount region of a surface of the support; and the conformal coating may be provided following placement of the die on the support.

Methods for forming connectors on die pads at a wafer level of processing include forming spots of a curable electrically conductive material over die pads and extending to or over the interconnect die edge; curing the conductive material; and in a wafer cutting procedure thereafter severing the spots. Also, die pad to z-interconnect connectors formed by the methods, and shaped and dimensioned accordingly. Also, stacked die assemblies and stacked die packages containing die prepared according to the methods and having die pad to z-interconnect connectors formed by the methods and shaped and dimensioned accordingly.
