摘要:
A treatment for a microelectronic device comprises a dicing tape (110) and a polymer composite film (120) having a pigment or other colorant added thereto and, in some embodiments, a pre-cure glass transition temperature greater than 50° Celsius. The film can comprise multiple layers, with one layer being tacky and the other layer non-tacky at a given temperature.

A microelectronic package is provided. The microelectronic package includes a semiconductor substrate and a die having a top surface and a bottom surface, wherein the bottom surface of the die is coupled to the semiconductor substrate. The microelectronic package also includes a nanomaterial layer disposed on the top surface of the die.
摘要:
Die warpage is controlled for the assembly of thin dies. In one example, a device having a substrate on a back side and components in front side layers is formed. A backside layer is formed over the substrate, the layer resisting warpage of the device when the device is heated. The device is attached to a substrate by heating.
摘要:
A layer or layers for use in package substrates and die spacers are described. The layer or layers include a plurality of ceramic wells lying within a plane and separated by metallic vias. Recesses within the ceramic wells are occupied by a dielectric filler material.
摘要:
A compliant structure for an electronic device comprises a substrate (110) composed of a first material (111) and a compliant zone (120) within the substrate. A plurality of solder joints (280) are located between, and form a connection between, the substrate and the electronic device (290). The compliant zone reduces the degree of deformation experienced by the solder joints due to thermal mismatch loading between the substrate and the die during attachment of the die to the substrate (chip attach). This reduction in solder joint deformation reduces the likelihood that the solder joints will crack.

Methods for fabricating a layer or layers for use in package substrates and die spacers are described. In one implementation the layer or layers are fabricated to include a plurality of ceramic wells lying within a plane and separated by metallic via with recesses within the ceramic wells being occupied by a dielectric filler material.
摘要:
A microelectronic package comprises a die (110) having a front side (111) containing active circuitry (115) and a back side (112) opposite the front side and a film (120) on the back side of the die. The film has a thickness (121) of at least 20 micrometers, a Young's modulus of at least 10 GPa, and a post-cure glass transition temperature of at least 100° Celsius.
