  • Publication number: 20250113561
    Abstract: In stacked transistor device, such as a complementary field-effect-transistor (CFET) device, different strain materials may be used in different layers, e.g., a tensile material is deposited in a first isolation region in the PMOS layer, and a compressive material is deposited in second isolation region in the NMOS layer. The strain materials may be stacked, such that the second isolation region may be positioned over the first isolation region. In some cases, in one or both of the isolation regions, a liner material is included between the strain material and the source and drain regions. Certain embodiments provide independent tuning of strain forces in a stacked transistor device. Different materials are selected for different layers in the stacked device to provide favorable performance enhancement or tuning (e.g., adjustment of the threshold voltage) in NMOS and PMOS layers.

  • Patent number: 12244554
    Abstract: Systems and method for determining a topic cohesion measurement between a content item and a hyperlinked landing page are presented. In one embodiment, a plurality of content item signals is generated for the content item and a corresponding plurality of signals are generated for the hyperlinked landing page. An analysis of the corresponding signals is conducted to determine a measurement of topic cohesion, a topic cohesion score, between the content item and the hyperlinked landing page. A cohesion predictor model is trained to generate the predictive topic cohesion score between an input content item and a hyperlinked landing page. Upon a determination that the topic cohesion score is less than a predetermined threshold, remedial actions are taken regarding the hyperlink of the content item. Alternatively, positive actions may be carried out, including promoting the content item to others, associating advertisements with the content item, and the like.
