Abstract:
Embodiment of the present disclosure are directed to methods for forming an LMI landing pad on a silicon wafer. The method includes forming, on a substrate, a redistribution layer (RDL); forming, on the RDL and the substrate, a passivation layer covering the substrate and the RDL; forming, on the passivation layer, a patternable dielectric material layer; processing the patternable dielectric material layer to expose a portion of the passivation layer covering the RDL; processing the portion of the passivation layer covering the RDL to expose a portion of the RDL; and forming, on the exposed portion of the RDL, an LMI landing pad. The resulting wafer can include a redistribution line having a top portion and a sidewall portion; a passivation layer covering the sidewall portion; a dielectric layer covering the passivation layer; and a metal interface covering the top portion of the redistribution line.
Abstract:
A multi-layered contact to a semiconductor structure and a method of making is described. In one embodiment, the contact includes a discontinuous Chromium layer formed over the semiconductor structure. A discontinuous Titanium layer is formed directly on the Chromium layer, wherein portions of the Titanium layer extend into at least some of the discontinuous sections of the Chromium layer. A discontinuous Aluminum layer is formed directly on the Chromium layer, wherein portions of the Aluminum layer extend into at least some of the discontinuous sections of the Titanium layer and the Chromium layer.
Abstract:
Ground shielding is achieved by a conductor shield having conductive surfaces that immediately surround individual chips within a fan-out wafer level package (FOWLP) module or device. Intra-module shielding between individual chips within the FOWLP module or device is achieved by electromagnetic or radio-signal (RF) isolation provided by the surfaces of the conductor shield immediately surrounding each of the chips. The conductor shield is directly connected to one or more grounded conductor portions of a FOWLP to ensure reliable grounding.
Abstract:
The invention relates to a rectifier diode which has a base (2) and which can be pressed into a provided opening of a rectifier arrangement. A platform (3) forming one part with the base is arranged on the base, and a semiconductor chip (4) is secured to said platform and is connected to a head wire (8). According to the invention, a wall (9) surrounding the platform is provided which ensures a low, homogenous level of bending strain on the supporting surface of the chip, and in comparison with a wall-free structure, said wall leads to uncritical centring of the chip during production. Moreover, semiconductor chips which are not that well centred no longer alter the reliability of the rectifier diode.
