  • Patent number: 8907718
    Abstract: There is described a passive heater-and-diode multiplexing network for selective addressing of thermally-coupled and electrically-disconnected fuses within a passive device network (resistor/capacitor/inductor) or within an application circuit.
    Type: Grant
    Filed: March 4, 2010
    Date of Patent: December 9, 2014
    Assignee: Sensortechnics GmbH
    Inventors: Saed Salman, Oleg Grudin, Leslie M. Landsberger, Gennadiy Frolov, Tommy Tsang, Zhen-grong Huang
  • Patent number: 8847117
    Abstract: There is described a method for stabilizing a post-trimming resistance of a thermally isolated electrical component made from a thermally mutable material, the method comprising: generating at least one heating pulse, the at least one heating pulse having an initial amplitude corresponding to a trimming temperature, a slope corresponding to a given cooling rate and a duration corresponding to a given cooling time; and applying the at least one heating pulse to one of the thermally isolated electrical component and a heating device in heat transfer communication with the thermally isolated electrical component, after a trimming process, in order to cause the electrical component to cool in accordance with the given cooling rate, the given cooling rate being slower than a passive cooling rate determined by the thermal isolation of the electrical component.

  • Patent number: 8111128
    Abstract: A method for arranging a plurality of thermally isolated microstructures over at least one cavity, each of the microstructures housing at least part of a thermally-trimmable resistor, the thermally-trimmable resistor having at least a functional resistor, the method comprising: providing pairs of facing microstructures; grouping together sets of pairs of facing microstructures, each of the sets having at least one pair of facing microstructures; and arranging microstructures within a given set to have each microstructure exposed to heat from a same number of facing, side, and diagonal neighbors of microstructures from a same resistor.
