A convex corner of the lead frame proximate to a geometric center of the lead frame may be rounded to include a radius of curvature of at least two times a greatest thickness of the die-attach pad. The thickness of the die-attach pad may be measured in a direction perpendicular to a major surface of the die-attach pad.

  • Patent number: 11769722
    Abstract: A method of forming a metal-insulator-metal (MIM) capacitor with copper top and bottom plates may begin with a copper interconnect layer (e.g., Cu MTOP) including a copper structure defining the capacitor bottom plate. A passivation region is formed over the bottom plate, and a wide top plate opening is etched in the passivation region, to expose the bottom plate. A dielectric layer is deposited into the top plate opening and onto the exposed bottom plate. Narrow via opening(s) are then etched in the passivation region. The wide top plate opening and narrow via opening(s) are concurrently filled with copper to define a copper top plate and copper via(s) in contact with the bottom plate. A first aluminum bond pad is formed on the copper top plate, and a second aluminum bond pad is formed in contact with the copper via(s) to provide a conductive coupling to the bottom plate.

  • Patent number: 11764772
    Abstract: A gate-drive controller for a power semiconductor device includes a master control unit (MCU) and one or more comparators that compare the output signal of the power semiconductor device to a reference value generated by the MCU. The MCU, in response to a turn-off trigger signal, generates a first intermediate drive signal for the power semiconductor device and generates a second intermediate drive signal, different from the first drive signal, when a DSAT signal indicates that the power semiconductor device is experiencing de-saturation. The MCU generates a final drive signal for the power semiconductor when the output signal of the one or more comparators indicates that the output signal of the power semiconductor device has changed relative to the reference value. The controller may also include a timer that causes the drive signals to change in predetermined intervals when the one or more comparators do not indicate a change.

  • Publication number: 20230291606
    Abstract: An apparatus may be communicatively coupled to other nodes in a network. The apparatus may include a control circuit configured to repeatedly issue transmission cycles to the other nodes. A given transmission cycle may include a least one send slot for each of the other nodes to send data. The control circuit may be configured to initiate transmission cycles by issuing beacon signals to the other nodes. The control circuit may be configured to determine when to issue a beacon signal in a given transmission cycle by determining that all of the other nodes have completed all associated send slots in an immediately previous transmission cycle and based upon a determination of the completion of the other nodes' transmission, delaying transmission of the beacon signal for the given transmission cycle.

  • Patent number: 11735516
    Abstract: An array of metal-oxide-metal (MOM) capacitors formed in an integrated circuit (IC) structure may be used for evaluating misalignments between patterned layers of the IC structure. The array of MOM capacitors may be formed in a selected set of patterned layers, e.g., a via layer formed between a pair of metal interconnect layers. The MOM capacitors may be programmed with different patterned layer alignments (e.g., built in to photomasks or reticles used to form the patterned layers) to define an array of different alignments. When the MOM capacitors are formed on the wafer, the actual patterned layer alignments capacitors may differ from the programmed layer alignments due a process-related misalignment. The MOM capacitors may be subjected to electrical testing to identify this process-related misalignment, which may be used for initiating a correcting action, e.g., adjusting a manufacturing process or discarding misaligned IC structures or devices.

    Abstract: An integrated circuit device may include a multi-material toothed bond pad including (a) an array of vertically-extending teeth formed from a first material, e.g., aluminum, and (b) a fill material, e.g., silver, at least partially filling voids between the array of teeth. The teeth may be formed by depositing and etching aluminum or other suitable material, and the fill material may be deposited over the array of teeth and extending down into the voids between the teeth, and etched to expose top surfaces of the teeth. The array of teeth may collectively define an abrasive structure. The multi-material toothed bond pad may be bonded to another bond pad, e.g., using an ultrasonic or thermosonic bonding process, during which the abrasive teeth may abrade, break, or remove unwanted native oxide layers formed on the respective bond pad surfaces, to thereby create a direct and/or eutectic bonding between the bond pads.
