  • Publication number: 20220230883
    Abstract: In certain examples, methods and semiconductor structures are directed to use of a doped buried region (e.g., Mg-dopant) including a III-Nitride material and having a diffusion path (“ion diffusion path”) that includes hydrogen introduced by using ion implantation via at least one ion species. An ion implantation thermal treatment causes hydrogen to diffuse through the ion implanted path and causes activation of the buried region. In more specific examples in which such semiconductor structures have an ohmic contact region at which a source of a transistor interfaces with the buried region, the ohmic contact region is without etching-based damage due at least in part to the post-ion implantation thermal treatment.

  • Publication number: 20220156168
    Abstract: In product testing, a script prioritization tool (102) is used to intelligently prioritize the execution sequence of test scripts. This tool creates a repository of test outputs from the executions of test scripts and analyzes the outputs to train and deploy a machine learning, ML, model that defines the priority of the scripts that may need to be executed and the scripts whose execution may be skipped without affecting the quality of testing. Scripts that are more likely to fail and/or are time consuming to execute are prioritized, while other scripts may be skipped. The ML model ranks the scripts based on the average execution time of the script, a count of the execution failures of the script, a count of the number of execution retries for the script, and the most recent failure time of the script. The scripts can be executed based on their rankings for efficiency and time-saving.

  • Publication number: 20200227429
    Abstract: A driver circuit for a three-dimensional (3D) memory device has a super junction structure as a field management structure. The super junction structure could be referred to as an extended junction structure, which distributes the electrical field of the junction between the vertical channel and the gate conductor for a string driver. The vertical channel includes a channel conductor to connect vertically between a source conductor and a drain conductor. The extended junction structure extends in parallel with the vertical channel conductor, extending vertically toward the drain conductor, having a height greater than a height of the gate conductor.

  • Publication number: 20200227525
    Abstract: A driver circuit for a three-dimensional (3D) memory device has a field management structure electrically coupled to a gate conductor. The field management structure causes an electric field peak in a vertical channel of the 3D memory device when a voltage differential exists between the source conductor and the drain conductor and the gate conductor is not biased. The electrical field peak can adjust the electrical response of the driver circuit, enabling the circuit to have a higher breakdown threshold voltage and improved drive current. Thus, the driver circuit can enable a scalable vertical string driver that is above the memory array instead of under the memory array circuitry.
