  • Publication number: 20230068273
    Abstract: The present disclosure is directed to semiconductor packages manufactured utilizing a leadframe with varying thicknesses. The leadframe with varying thicknesses has a reduced likelihood of deformation while being handled during the manufacturing of the semiconductor packages as well as when being handled during a shipping process. The method of manufacturing is not required to utilize a leadframe tape based on the leadframe with varying thicknesses. This reduces the overall manufacturing costs of the semiconductor packages due to the reduced materials and steps in manufacturing the semiconductor packages as compared to a method that utilizes a leadframe tape to support a leadframe. The semiconductor packages may include leads of varying thicknesses formed by utilizing the leadframe of varying thicknesses to manufacture the semiconductor packages.

  • Patent number: 11573303
    Abstract: Disclosed herein is a system for detecting rotational speed and early failures of an electronic device. The system includes a rotating disk affixed to a rotating shaft of the electronic device. The rotating disk has projections extending from its periphery. A time of flight ranging system determines distance to the projections extending from the rotating disk. Processing circuitry determines a rotational speed of the rotating shaft from the determined distances to the projections extending from the rotating disk, and detects whether the electronic device is undergoing an early failure from the determined distances to the projections extending from the rotating disk. Rotational speed is determined from the time between successive peaks in the determined distances, and early failures (for example, due to wobble of the shaft) are determined where the peaks vary unexpectedly in magnitude.

  • Publication number: 20230036201
    Abstract: A semiconductor package device having a porous copper adhesion promoter layer is provided. The porous copper adhesion promoter layer developed via de-metallization of the intermetallic compound layer grown after the thermal treatment of a thin metal layer plated on the copper base material. The highly selective de-metallization of the intermetallic compound layer ensures that the plated surfaces are not affected and does not create wire-bondability issues. The porous copper layer solves the delamination between the carrier and the epoxy molding compound by providing mechanical interlock features. Further, increasing the surface area of contact between the carrier and the epoxy molding compound improves the mechanical interlock features.

  • Publication number: 20230018529
    Abstract: Energy bands of a thin film containing molecular clusters are tuned by controlling the size and the charge of the clusters during thin film deposition. Using atomic layer deposition, an ionic cluster film is formed in the gate region of a nanometer-scale transistor to adjust the threshold voltage, and a neutral cluster film is formed in the source and drain regions to adjust contact resistance. A work function semiconductor material such as a silver bromide or a lanthanum oxide is deposited so as to include clusters of different sizes such as dimers, trimers, and tetramers, formed from isolated monomers. A type of Atomic Layer Deposition system is used to deposit on semiconductor wafers molecular clusters to form thin film junctions having selected energy gaps. A beam of ions contains different ionic clusters which are then selected for deposition by passing the beam through a filter in which different apertures select clusters based on size and orientation.

  • Patent number: 11552007
    Abstract: The present disclosure is directed to a leadframe having a recess in a body of the leadframe to collect glue overflowing from the manufacturing process of coupling a semiconductor die to the leadframe. The recess extends beneath an edge of the semiconductor die so that any tendency of the glue to adhere to the semiconductor die is counteracted by a tendency of the glue to adhere to a wall of the recess and at least partially fill the volume of the recess. In addition, the recess for collecting adhesive may also form a mold lock on an edge of the leadframe, the mold lock providing a more durable connection between the leadframe and an encapsulant during physical and temperature stresses.

  • Patent number: 11515418
    Abstract: A tunneling transistor is implemented in silicon, using a FinFET device architecture. The tunneling FinFET has a non-planar, vertical, structure that extends out from the surface of a doped drain formed in a silicon substrate. The vertical structure includes a lightly doped fin defined by a subtractive etch process, and a heavily-doped source formed on top of the fin by epitaxial growth. The drain and channel have similar polarity, which is opposite that of the source. A gate abuts the channel region, capacitively controlling current flow through the channel from opposite sides. Source, drain, and gate terminals are all electrically accessible via front side contacts formed after completion of the device. Fabrication of the tunneling FinFET is compatible with conventional CMOS manufacturing processes, including replacement metal gate and self-aligned contact processes. Low-power operation allows the tunneling FinFET to provide a high current density compared with conventional planar devices.

  • Publication number: 20220358062
    Abstract: A microcontroller includes a memory, direct memory access (DMA) controllers and a microprocessor. The microprocessor maintains one or more memory protection (MP) configurations to control access to protected memory areas of the microcontroller. In response to a secure service call of an unsecure user-application, the microprocessor executes a state machine which disables interrupt requests, determining whether DMA controller configurations and MP configurations satisfy secure-service criteria. When the secure-service criteria are satisfied, at least one secure operation associated with the secure service call is performed, and memory areas accessed during the execution of the at least one secure operation are cleaned. The interrupt requests are re-enabled and a response to the secure service call is generated.

  • Patent number: 11495676
    Abstract: Stress is introduced into the channel of an SOI FinFET device by transfer directly from a metal gate. In SOI devices in particular, stress transfer efficiency from the metal gate to the channel is nearly 100%. Either tensile or compressive stress can be applied to the fin channel by choosing different materials to be used in the gate stack as the bulk gate material, a gate liner, or a work function material, or by varying processing parameters during deposition of the gate or work function materials. P-gates and N-gates are therefore formed separately. Gate materials suitable for use as stressors include tungsten (W) for NFETs and titanium nitride (TiN) for PFETs. An optical planarization material assists in patterning the stress-inducing metal gates. A simplified process flow is disclosed in which isolation regions are formed without need for a separate mask layer, and gate sidewall spacers are not used.
