Abstract:
Various aspects of an approach for routing die signals in an interior portion of a die using external interconnects are described herein. The approach provides for contacts coupled to circuits in the interior portion of the die, where the contacts are exposed to an exterior portion of the die. The external interconnects are configured to couple these contacts so that signals from the circuits in the interior portion of the die may be routed externally to the die. In various aspects of the disclosed approach, the external interconnects are protected by a packaging for the die.
Abstract:
Aspects and examples include electrical components and methods of forming electrical components. In one example, a method includes selecting a substrate, forming a pattern of a first conductive material on a top surface of the substrate, forming a pattern of a second conductive material on a bottom surface of the substrate, dicing the substrate into one or more die having a first diced surface and a second diced surface, securing the first diced surface of each of the one or more die to a retaining material, encapsulating the one or more die in an encapsulent to form a reconstituted wafer, and forming a pattern of a third conductive material on the second diced surface by metalizing a surface of the reconstituted wafer.
Abstract:
A method for fabricating a through interconnect on a semiconductor substrate includes the steps of forming a via on a first side of the substrate part way through the substrate, forming an electrically insulating layer on the first side and in the via, forming an electrically conductive layer at least partially lining the via, forming a first contact on the conductive layer in the via, and thinning the substrate from a second side at least to the insulating layer in the via. The method can also include the step of forming a second contact on a second side of the substrate in electrical contact with the first contact. The method can be performed on a semiconductor wafer to form a wafer scale interconnect component. In addition, the interconnect component can be used to construct semiconductor systems such as a light emitting diode (LED) systems.
Abstract:
An array of composite polymer-metal contact members adapted to form solder free electrical connections with a first circuit member. The contact members include a resilient polymeric base layer and an array of metalized traces printed on selected portions of the base layer. Conductive plating is applied to the metalized layer to create an array of conductive paths. The resilient polymeric base layer, the metalized layer, and the conductive plating have an aggregate spring constant sufficient to maintain distal portions of the contact members in a cantilevered configuration and to form a stable electrical connection between the distal portions and the first circuit member solely by compressive engagement.
Abstract:
A semiconductor wafer has a semiconductor substrate and films on the substrate. The substrate and/or the films have at least one etch line creating a discontinuous surface that reduces residual stress in the wafer. Reducing residual stress in the semiconductor wafer reduces warpage of the wafer when the wafer is thin. Additionally, isolation plugs may be used to fill a portion of the etch lines to prevent shorting of the layers.

Abstract:
An interconnect terminal is formed on a semiconductor die by applying an electrically conductive material in an aerosol form, for example by aerosol jet printing. Also, an electrical interconnect between stacked die, or between a die and circuitry in an underlying support such as a package substrate, is formed by applying an electrically conductive material in an aerosol form, in contact with pads on the die or on the die and the substrate, and passing between the respective pads. In some embodiments a fillet is formed at the inside corner formed by an interconnect sidewall of the die and a surface inboard from pads on an underlying feature (underlying die or support); and the electrically conductive material passes over a surface of the fillet.

Various embodiments include apparatus, systems, and methods having multiple dice arranged in a stack in which a defective cell may be replaced by a spare cell on the same die or a different die.
Abstract:
A nitride crystal or wafer with a removable surface layer comprises a high quality nitride base crystal, a release layer, and a high quality epitaxial layer. The release layer has a large optical absorption coefficient at wavelengths where the base crystal is substantially transparent and may be etched under conditions where the nitride base crystal and the high quality epitaxial layer are not. The high quality epitaxial layer may be removed from the nitride base crystal by laser liftoff or by chemical etching after deposition of at least one epitaxial device layer. The nitride crystal with a removable surface layer is useful as a substrate for a light emitting diode, a laser diode, a transistor, a photodetector, a solar cell, or for photoelectrochemical water splitting for hydrogen generation.
