Abstract:
Techniques are disclosed for forming a through-body- via (TBV) in a semiconductor die. In accordance with some embodiments, a TBV provided using the disclosed techniques includes a polymer-based barrier layer and an electrically conductive seed layer formed by applying an electrically conductive ink directly to the barrier layer and then curing it in situ. In some embodiments, after curing, the resultant seed layer may be a thin, substantially conformal, electrically conductive metal film over which the TBV interconnect metal can be deposited. In some example cases, a polyimide, parylene, benzocyclobutene (BCB), and/or polypropylene carbonate (PPC) barrier layer and an ink containing copper (Cu) and/or silver (Ag), of nanoparticle-based or metal complex -based formulation, may be used in forming the TBV. In some instances, the disclosed techniques may be used to address poor step coverage, low run rate, and/or high cost issues associated with existing physical vapor deposition (PVD) -based far- back-end-of-line (FBEOL) processes.
Abstract:
An apparatus comprises a semiconductor substrate having a device layer, a plurality of metallization layers, a passivation layer, and a metal bump formed on the passivation layer that is electrically coupled to at least one of the metallization layers. The apparatus further includes a solder limiting layer formed on the passivation layer that masks an outer edge of the top surface of the metal bump, thereby making the outer edge of the top surface non-wettable to a solder material.
Abstract:
The invention relates, in part, to methods for detecting, monitoring, measuring or assessing an interaction between at least two proteins. The invention also relates, in part, to methods for determining if a test compound, or a mix of compounds, modulates an interaction between at least two proteins. In some embodiments, determination is made possible via the use of two recombinant molecules, e.g., one of which contains a first protein cleavage site for a proteolytic molecules, and an activator of a gene. A second recombinant molecule may include a second protein and the proteolytic molecule. Various other formats are provided by the invention. In some embodiments, if the test compound binds to the first protein, a reaction is initiated whereby the activator is cleaved, and activates a reporter gene.
Abstract:
The described invention shows how multiple interactions between two proteins of interest can be determined by observing activation or lack thereof of intracellular proteins, following interaction of ligand and receptor.
Abstract:
Apparatus and methods of fabricating an under bump metallization structure including an adhesion layer abutting a conductive pad, a molybdenum-containing barrier layer abutting the adhesion layer, a wetting layer abutting the molybdenum-containing barrier layer, and high tin content solder material abutting the wetting layer. The wetting layer may be substantially subsumed in the high content solder forming an intermetallic compound layer. The molybdenum-containing barrier layer prevents the movement of tin in the high tin content solder material from migrating to dielectric layers abutting the conductive pad and potentially causing delamination and/or attacking any underlying structures, particularly copper structures, which may be present.
Abstract:
The present invention relates to Anopheles gambiae odorant receptor genes and methods for identifying odorant receptor genes. The invention provides nucleotide sequences of Anopheles gambiae odorant receptor genes, amino acid sequences of their encoded proteins (including peptides or polypeptides), and related products and methods. The nucleic acids of the invention may be operatively linked to promoter sequences and transformed into host cells. Methods of production of an odorant receptor protein (e.g., by recombinant means), and derivatives and analogs thereof, are provided. Antibodies to an odorant receptor protein, and derivatives and analogs thereof, are provided. Methods for identifying molecules that bind or modulate the activity of these odorant receptor genes are provided. Molecules found to bind or modulate the activity of odorant receptor genes may be formulated into pest control agents by providing a carrier. In a preferred embodiment, molecules that bind or modulate the activity of an odorant receptor gene from Anopheles gambiae but not others is desired. Methods to modify the insect behavior by modifying an odorant receptor are also provided.
Abstract:
An integrated circuit apparatus comprises a semiconductor substrate having a plurality of devices formed thereon, one or more metallization layers to interconnect the plurality of devices, and a bond pad formed over the one or more metallization layers and electrically coupled to at least one of the metallization layers. A first passivation layer is formed over the bond pad and over the metallization layers and a redistribution interconnect formed on the passivation layer. A first via formed through the first passivation layer electrically couples the redistribution interconnect to the bond pad. A second passivation layer is formed on the redistribution interconnect to prevent thermomechanical degradation and improve electromigration performance. A dielectric layer is formed on the second passivation layer and a die-side bump is formed on the dielectric layer. A second via formed through the dielectric layer and through the second passivation layer electrically couples the die-side bump to the redistribution interconnect.
Abstract:
The invention involves receptor complexes which include, inter alia, a receptor protein, and a reporter molecule. There is at least one unnatural, or non-naturally occurring amino acid in the receptor molecule. When a ligand interacts with the receptor, the interaction causes the reporter to generate a detectable signal. The complexes are useful in cell free, assay systems and may be used as part of micelles.

Abstract:
Techniques are disclosed for forming a through-body-via (TBV) isolated coaxial capacitor in a semiconductor die. In some embodiments, a cylindrical capacitor provided using the disclosed techniques may include, for example, a conductive TBV surrounded by a dielectric material and an outer conductor plate. The TBV and outer plate can be formed, for example, so as to be self-aligned with one another in a coaxial arrangement, in accordance with some embodiments. The disclosed capacitor may extend through the body of a host die such that its terminals are accessible on the upper and/or lower surfaces thereof. Thus, in some cases, the host die can be electrically connected with another die to provide a die stack or other three-dimensional integrated circuit (3D IC), in accordance with some embodiments. In some instances, the disclosed capacitor can be utilized, for example, to provide integrated capacitance in a switched-capacitor voltage regulator (SCVR).
