Abstract:
Microelectronic assemblies, related devices and methods, are disclosed herein. In some embodiments, a microelectronic component may include a substrate having a first face and an opposing second face, wherein the substrate includes a through-substrate via (TSV); a first mold material region at the first face, wherein the first mold material region includes a first through-mold via (TMV) conductively coupled to the TSV; and a second mold material region at the second face, wherein the second mold material region includes a second TMV conductively coupled to the TSV.
Abstract:
An interferometer for characterizing a sample, the interferometer including a light emitter to produce a light beam. A wavelength modulator can dither a wavelength of the light beam to produce an input beam having an oscillating wavelength. A beam splitter can be configured to divide the input beam into a reference beam and a measurement beam. The reference beam can reflect from a mirror having a fixed position and return to the beam splitter. The measurement beam can reflect from the sample and return to the beam splitter. The beam splitter can interfere the received reference beam and measurement beam to form an output beam. A detector can convert the output beam to an electrical signal. A processor can control the wavelength modulator, receive the electrical signal, and determine a distance to the sample based on the electrical signal and the oscillating wavelength of the input beam.

In accordance with disclosed embodiments, there are provided methods, systems, and apparatuses for gradient encapsulant protection of devices in stretchable electronic. For instance, in accordance with one embodiment, there is an apparatus with an electrical device on a stretchable substrate; one or more stretchable electrical interconnects coupled with the electrical device; one or more electrical components electrically coupled with the electrical device via the one or more stretchable electrical interconnects; and a gradient encapsulating material layered over and fully surrounding the electrical device and at least a portion of the one or more stretchable electrical interconnects coupled thereto, in which the gradient encapsulating material has an elastic modulus greater than the stretchable substrate and in which the elastic modulus of the gradient encapsulating material is less than the electrical device. Other related embodiments are disclosed.
Abstract:
A microelectronic die may be formed with chamfer corners for reducing stresses which can lead to delamination and/or cracking failures when such a microelectronic die is incorporated into a microelectronic package. In one embodiment, a microelectronic die may include at least one substantially planar chamfering side extending between at least two adjacent sides of a microelectronic die. In another embodiment, a microelectronic die may include at least one substantially curved or arcuate chamfering side extending between at least two adjacent sides of a microelectronic die.
Abstract:
Some embodiments relate to an electronic package. The electronic package includes a substrate and a die attached to the substrate. The electronic package further includes an underfill positioned between the die and the substrate due to capillary action. A support surrounds the die. The support provides the same beneficial fillet geometry on all die edges. Therefore, the support provides similar stress reduction on all die edges. Other embodiments relate to method of fabricating an electronic package. The method includes attaching a die to a substrate and inserting an underfill between the die and the substrate using capillary action. The method further includes placing a support around the die such that the support surrounds the die.
Abstract:
Embodiments of the present description include methods for attaching a microelectronic device to a microelectronic substrate with interconnection structures after disposing of an underfill material on the microelectronic device, wherein filler particless within the underfill material may be repelled away from the interconnection structures prior to connecting the microelectronic device to the microelectronic structure. These methods may include inducing a charge on the interconnection structures and may include placing the interconnection structures between opposing plates and producing a bias between the opposing plates after depositing the underfill material on the interconnection structures.
