  • Patent number: 11955379
    Abstract: A metal adhesion layer may be formed on a bottom and a sidewall of a trench prior to formation of a metal plug in the trench. A plasma may be used to modify the phase composition of the metal adhesion layer to increase adhesion between the metal adhesion layer and the metal plug. In particular, the plasma may cause a shift or transformation of the phase composition of the metal adhesion layer to cause the metal adhesion layer to be composed of a (111) dominant phase. The (111) dominant phase of the metal adhesion layer increases adhesion between the metal adhesion layer.

  • Patent number: 11798185
    Abstract: An image analysis method is provided. In the image analysis method, a to-be analyzed image is inputted into a region-based convolutional neural network (RCNN) model to obtain a masked image outputted from the RCNN. The center of a masked object in the masked image is calculated. The center is regarded as an origin of coordinate and the farthest coordinate point from the origin of coordinate in each of the four quadrants relative to the origin of coordinate are searched. The image analysis block is generated for each of the farthest coordinate points. The post-processing is performed on the image analysis blocks to obtain an object range.
