  • Publication number: 20240168390
    Abstract: In the semiconductor industry, lithography refers to a manufacturing process in which light is projected through a geometric design on a mask to illuminate the design on a semiconductor wafer. The wafer has a light-sensitive material (i.e. resist) on its surface which, when illuminated by the light, causes the design to be etched onto the wafer. However, this lithography process does not perfectly transfer the design to the wafer, particularly because some diffracted light will inevitably distort the pattern etched onto the wafer (i.e. the resist image). To address this issue in lithography, an inverse lithography technology has been developed which optimizes the mask to match the desired shapes on the wafer. The present disclosure improves current inverse lithography technology by employing machine learning for mask optimization.

  • Patent number: 11900234
    Abstract: Apparatuses and methods of manufacturing same, systems, and methods for generating a convolutional neural network (CNN) are described. In one aspect, a minimal CNN having, e.g., three or more layers is trained. Cascade training may be performed on the trained CNN to insert one or more intermediate layers until a training error is less than a threshold. When cascade training is complete, cascade network trimming of the CNN output from the cascade training may be performed to improve computational efficiency. To further reduce network parameters, convolutional filters may be replaced with dilated convolutional filters with the same receptive field, followed by additional training/fine-tuning.
