    Abstract: Ferroelectric random access memory (FRAM) capacitors and methods of forming FRAM capacitors are provided. An FRAM capacitor may be formed between adjacent metal interconnect layers or between a silicided active layer (e.g., including MOSFET devices) and a first metal interconnect layer. The FRAM capacitor may be formed by a damascene process including forming a tub opening in a dielectric region, forming a cup-shaped bottom electrode, forming a cup-shaped ferroelectric element in an interior opening defined by the cup-shaped bottom electrode, and forming a top electrode in an interior opening defined by the cup-shaped ferroelectric element. The FRAM capacitor may form a component of an FRAM memory cell. For example, an FRAM memory cell may include one FRAM capacitor and one transistor (1T1C configuration) or two FRAM capacitors and two transistor (2T2C configuration).

  • Publication number: 20230342158
    Abstract: An article of manufacture includes a non-transitory machine-readable medium. The medium includes instructions. The instructions, when read and executed by a processor, cause the processor to identify a first input instruction in a code stream to be executed, determine that the first input instruction includes an atomic operation designation, and selectively block interrupts for a duration of execution of the first input instruction and a second input instruction. The second input instruction is to immediately follow the first input instruction in the code stream.

    Abstract: An apparatus includes a test circuit to receive signals from a piezoelectric horn and a control circuit to determine whether to operate the apparatus in a silent test mode or a normal mode. The apparatus includes a control circuit to, based on a determination to operate in the normal mode, enable a driver circuit to drive the piezoelectric horn so as to output sound when activated by the driver circuit. The test circuit is to, based on a determination to operate in the silent test mode, cause the piezoelectric horn to generate a piezoelectric response, wherein the piezoelectric horn is silent while generating the piezoelectric response during the silent test mode, and cause evaluation of whether or not the piezoelectric horn is working correctly based upon the received signals from the piezoelectric horn.

  • 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.
