    Abstract: A method for integrated circuit design with delay verification includes storing configuration files for a slew-rate Machine Learning (ML) model, a net-delay ML model and a cell-delay ML model. A user design is received, slew-rate feature values, net-delay feature values and cell-delay feature values are extracted from the user design, the configuration files are loaded to form inference cores, and operations of the slew-rate inference core are performed to calculate predicted slew-rate values that are sent to ML design tools. Operations of the net-delay inference core are performed to calculate predicted net-delay values that are sent to the ML design tools. Operations of the cell-delay inference core are performed to generate predicted cell-delay values that are sent to the ML design tools. The user design is iterated until a user design is obtained that is free of timing violations.

    Abstract: A packaged electronic die having a micro-cavity and a method for forming a packaged electronic die. The packaged electronic die includes a photoresist frame secured to the electronic die and extending completely around the device. The photoresist frame is further secured to a first major surface of a substrate so as to form an enclosure around the device. Encapsulant material extends over the electronic die and around the sides of the electronic die. The encapsulant material is in contact with the first major surface of the substrate around the entire periphery of the electronic die so as to form a seal around the electronic die.

    Abstract: An SEU immune flip-flop includes a master stage data latch, being transparent in response to a clock signal first state and being latched in response to a clock signal second state; a slave stage data latch; and a scan slave latch having an input coupled to the slave stage data latch scan output, being transparent in response to the clock signal second state and being latched in response to the clock signal first state. The slave stage data latch includes a switched inverter disabled when the slave latch is in a transparent state and enabled when the slave latch is in a latched state having a time delay longer than an SEU time period.

    Abstract: A method and apparatus for decoding are disclosed. The method includes receiving a first Forward Error Correction (FEC) block of read values, starting a hard-decode process in which a number of check node failures is identified and, during the hard-decode process comparing the identified number of check node failures to a decode threshold. When the identified number of check node failures is not greater than the decode threshold the hard-decode process is continued. When the identified number of check node failures is greater than the decode threshold, the method includes: stopping the hard-decode process prior to completion of the hard-decode process; generating output indicating that additional reads are required; receiving one or more additional FEC blocks of read values, mapping the first FEC block of read values and the additional FEC blocks of read values into soft-input values; and performing a soft-decode process on the soft-input values.

    Abstract: A high-voltage termination for a semiconductor device includes a substrate, an implanted device region, a shallow trench adjacent to the implanted device region, and a doped extension region between the implanted device region and a first edge of the shallow trench adjacent to the implanted device region. A junction termination extension region is formed in the shallow trench contacting the extension region and extending past a second edge of the shallow trench opposite the implanted device region. An insulating layer is formed over at least a portion of the extension region and over the junction termination extension region. A metal layer is formed over the insulating layer.

    Abstract: This disclosure is directed to a method of producing a smooth surface for a dielectric coating (34) that is located above the surface of semiconductor substrate (10) containing doped regions (26, 32, 34) of a semiconductor device. Sharp edges (40, 42) formed in the dielectric coating (34) during certain semiconductor processing steps are removed using a deposition process to deposit a separate insulating layer (48) on the dielectric coating (34) containing the sharp edges (40, 42) followed by an annealing operation and the subsequent removal of the separate insulating layer (48) to permit the subsequent formation of electrodes (50, 52, 54) on a smooth surface of the dielectric coating (34).
