  • Publication number: 20240219825
    Abstract: Various examples described herein include a correction for a layer-to-layer or substrate-to-substrate overlay alignment based upon feedback from critical-dimension (CD) measurements of locations of various features that are to be formed on subsequently formed layers of a substrate with regard to locations of similar features on previously formed layers. The layer-to-layer or substrate-to-substrate overlay-alignment feedback can be enhanced by determining positions of multiple ones of the features on each of the formed layers with respect to the first layer in the stack. Further, the layer-to-layer or substrate-to-substrate overlay-alignment feedback can be enhanced by determining positions of multiple ones of the features on each of the formed layers with respect to the previously formed layer. Overlay-alignment errors may be sent back to a photolithographic exposure tool. An accumulated overlay error can be flagged. Other techniques and methods are also disclosed.

  • Publication number: 20210234214
    Abstract: The present disclosure relates to an energy module having a plurality of energy generating cells, and at least one cooling plate having opposing surfaces. The cooling plate is disposed between an adjacent pair of the energy generating cells such that the opposing surfaces of the cooling plate are in contact with surfaces of the adjacent pair of energy generating cells. The cooling plate has at least one coolant flow channel configured to receive a coolant flow therethrough to limit propagation of heat from one to the other of either one of the adjacent pair of energy generating cells when either one of the adjacent pair of energy generating cells fails.
