  • Publication number: 20250244661
    Abstract: Methods for removing haze defects from a photomask or reticle are disclosed. The photomask is placed into a chamber which includes a hydrogen atmosphere. The photomask is then exposed to radiation. The energy from the radiation, together with the hydrogen, causes decomposition of the haze defects. The methods can be practiced on-site and quickly, without the need for wet chemicals or the need to remove the pellicle before cleaning of the photomask. A device for conducting the methods is also disclosed herein.

  • Publication number: 20250053611
    Abstract: Embodiment described herein provide systems, apparatuses and methods for convoluting a filter (“kernel”) to input data in the form of an input array by reusing computations of repeated data entries in the input array due to convolution movements from one convolution step to the next. In one embodiment, to compute a convolution of an input matrix and a filter matrix, instead of unrolling data entries from the input matrix of each convolution step into an input vector, only non-repeated new data entries at each convolution step may be added to the input vector. An input mapping circuit that implements an input parameter mapping matrix may then iteratively map data entries of the input vector to different weight registers that corresponds to weights in the filter matrix.
