  • Patent number: 11079745
    Abstract: A system for rapidly adapting production of a product based on classification of production data using a classifier trained on prior production data is provided. A production control system includes a learning system and an adaptive system. The learning system trains a production classifier to label or classify previously collected production data. The adaptive system receives production data in real time and classifies the production data in real time using the production classifier. If the classification indicates a problem with the manufacturing of the product, the adaptive system controls the manufacturing to rectify the problem by taking some corrective action. The production classifier is trained using bootstrap data and corresponding example data extracted from prior production data. Once the bootstrap data is labeled, the corresponding example data is automatically labeled for use as training data.

  • Patent number: 11043569
    Abstract: A semiconductor device and method of formation are provided. The semiconductor device includes a channel surrounding a dielectric tube and a gate surrounding the channel. The dielectric tube comprises a high dielectric constant material that has or conducts few to no carriers, such as electrons or holes. The presence of the dielectric tube confines carriers to the channel, which is in close proximity to the gate. The proximity of the channel, and the carriers therein, to the gate affords greater control to the gate over the carriers, thus allowing a length of the channel to be decreased while experiencing little to no short channel effects, such as current leakage through the channel.
