  • Publication number: 20240162175
    Abstract: The present disclosure is directed to embodiments of a conductive structure on a conductive barrier layer that separates the conductive structure from a conductive layer on which the conductive barrier layer is present. A gap or crevice extends along respective surfaces of the conductive structure and along respective surfaces of one or more insulating layers. The gap or crevice separates the respective surfaces of the one or more insulating layers from the respective surfaces of the conductive structure. The gap or crevice provides clearance in which the conductive structure may expand into when exposed to changes in temperature. For example, when coupling a wire bond to the conductive structure, the conductive structure may increase in temperature and expand into the gap or crevice. However, even in the expanded state, respective surfaces of the conductive structure do not physically contact the respective surfaces of the one or more insulating layers.

    Abstract: In various embodiments, the present disclosure provides semiconductor devices, packages, and methods. In one embodiment, a device includes a die pad, a lead that is spaced apart from the die pad, and an encapsulant on the die pad and the lead. A plurality of cavities extends into at least one of the die pad or the lead to a depth from a surface of the at least one of the die pad or the lead. The depth is within a range from 0.5 ?m to 5 ?m. The encapsulant extends into the plurality of cavities. The cavities facilitate improved adhesion between the die pad or lead and the encapsulant, as the cavities increase a surface area of contact with the encapsulant, and further increase a mechanical interlock with the encapsulant, as the cavities may have a rounded or semi-spherical shape.

  • Patent number: 11984151
    Abstract: A circuit includes a memory array with SRAM cells connected in rows by word lines and in columns by bit lines. A row controller circuit simultaneously actuates, through a word line driver circuit for each row, word lines in parallel for an in-memory compute operation. A column processing circuit processes analog voltages developed on the bit lines in response to the simultaneous actuation to generate a decision output for the in-memory compute operation. A bit line precharge circuit generates a precharge voltage for application to each pair of bit lines. The precharge voltage has a first voltage level (not greater than a positive supply voltage for the SRAM cells) when the memory array is operating in a data read/write mode. The precharge voltage has a second voltage level (greater than the first voltage level) in advance of the simultaneous actuation of the word lines for the in-memory compute operation.

  • Publication number: 20240151844
    Abstract: A flash analog-to-digital converter (ADC) receives an input control signal and performs coarse tuning of a frequency of an output signal, produced between first and second nodes having an inductance coupled therebetween. The flash ADC quantizes an operating frequency range for the output signal produced between the first and second nodes as M·?f, where M is an integer from 0 to N?1, where N is a number of intervals into which a frequency range for the output signal is divided, and where ?f is a resulting frequency step produced by the quantizing. The value of M is generated based upon the input control signal and a word controlling switches of a plurality of switched capacitance circuits associated with the first and second nodes to close ones of those switches associated with the control word to coarsely tune the frequency of the output signal.

  • Publication number: 20240154515
    Abstract: A converter system includes a reference buffer buffering a reference input to produce a DAC reference, operating from a reference feedback voltage generated by a reference divider. A tail buffer generates a tail voltage from an input voltage generated from the DAC reference by a tail divider. An R-2R type DAC utilizes an R-2R ladder to generate a DAC output from a code. This ladder has a tail resistor coupled to the tail voltage. A feedback buffer buffers the DAC output to produce a converter reference. A DC-DC converter generates a DC output from a DC input, based upon a converter feedback voltage. A feedback divider coupled between the DC output and the converter reference generates the converter feedback voltage. Control circuitry selectively taps the reference divider to produce the reference feedback voltage (performing gain trimming) and selectively taps the tail divider to produce the input voltage (performing offset trimming).

  • Publication number: 20240151828
    Abstract: A pixel includes a SPAD having a cathode connected to a first node and an anode coupled to a first negative voltage, and a transistor circuit coupled between a supply voltage and a third node, that turns on in response to an enable signal. A cascode transistor connected between the third node and the first node is controlled by a cascode control signal. A cathode setting capacitor is connected between the first node and ground. A readout inverter is coupled between the intermediate node and an output node and generates an output signal. Turn-on of the transistor circuit sources current from the supply voltage node to the cathode setting capacitor, setting a reverse bias voltage across the SPAD to greater than its breakdown voltage. A photon impinging upon the SPAD cause avalanche of the SPAD which, when occurring after turn off of the transistor circuit, discharges the cathode setting capacitor.
