  • Patent number: 12268103
    Abstract: Phase change material (PCM) switches and methods of fabrication thereof that provide improved thermal confinement within a phase change material layer. A PCM switch may include a dielectric capping layer between a heater pad and the phase change material layer of the PCM switch that is laterally-confined such opposing sides of the dielectric capping layer the heater pad may form continuous surfaces extending transverse to the signal transmission pathway across the PCM switch. Heat transfer from the heater pad through the dielectric capping layer to the phase change material layer may be predominantly vertical, with minimal thermal dissipation along a lateral direction. The localized heating of the phase change material may improve the efficiency of the PCM switch enabling lower bias voltages, minimize the formation of regions of intermediate resistivity in the PCM switch, and improve the parasitic capacitance characteristics of the PCM switch.

  • Patent number: 12261070
    Abstract: This chip mounting system simultaneously images an alignment mark disposed on a substrate (WT) and an alignment mark disposed on a chip (CP), with the alignment marks disposed on the substrate (WT) and the chip (CP) being separated by a first distance at which the alignment marks fall within a depth-of-field range of imaging devices. The chip mounting system calculates a relative positional deviation amount between the substrate (WT) and the chip (CP) from the imaged images of the alignment marks imaged by the imaging devices and, based on the calculated positional deviation amount, relatively moves the chip (CP) with respect to the substrate (WT) in a direction in which the positional deviation amount therebetween decreases.
