    Abstract: A heat dissipating device. The heat dissipating device includes a receiving area open on at least one side, and a mosaic segment, arranged in the receiving area, which includes a thermally conductive and elastic compensation element and a thermally conductive low-adherent contact region. The thermally conductive and elastic compensation element rests against the inner surface of the base of the receiving area. The thermally conductive low-adherent contact region at least partly protrudes out of the receiving area at the open face of the receiving area lying opposite the base. The outer surface of the base of the receiving area forms a rigid first contact surface for a heat source or a heat sink, and the thermally conductive low-adherent contact region of the at least one mosaic segment forms a flexible second contact surface for the heat sink or the source.

  • Publication number: 20230041856
    Abstract: A process for fabricating a transversely-excited film bulk acoustic resonator (XBAR) and that XBAR are described. A sacrificial pillar is formed on a surface of a piezoelectric wafer and a highly conforming dielectric layer is deposited on the piezoelectric wafer to bury the sacrificial pillar. The highly conforming dielectric layer is polished to form a planar surface and to leave a thickness of the highly conforming dielectric that covers the sacrificial pillar. The planar surface of the highly conforming dielectric layer is bonded to a surface of a substrate wafer. A conductor pattern is formed on a front surface of the piezoelectric plate and holes are formed through the piezoelectric wafer to the sacrificial pillar. The sacrificial pillar is removed using an etchant introduced through the holes in the piezoelectric wafer to form a cavity under a diaphragm of the piezoelectric wafer spanning the cavity.

    Abstract: An acoustic resonator device is formed that reduces a thermal coefficient of expansion mismatch between a piezoelectric plate and a silicon substrate by bonding the front surface of the silicon substrate having a filled and planarized sacrificial tub to a piezoelectric substrate and thinning the silicon substrate by removing material from a back surface. That back surface is then bonded to a handle wafer having a thermal coefficient of expansion (TCE) closer to a TCE of the piezoelectric substrate than a TCE of the silicon substrate and thinning the piezoelectric substrate to a target piezoelectric membrane thickness to form a piezoelectric plate. A conductor pattern is formed on the thinned piezoelectric plate and the sacrificial tub is removed to form a cavity and release a membrane of the piezoelectric plate using an etchant introduced through holes in the piezoelectric plate.

  • Publication number: 20220360251
    Abstract: Acoustic resonators, filters, and methods. A filter includes a piezoelectric plate supported by a substrate; and three or more diaphragms of the piezoelectric plate spanning a respective cavity in the substrate. A conductor pattern on the plate has interdigital transducers (IDTs) of three or more acoustic resonators. Each IDT has two sets of interleaved fingers extending from two busbars respectively. Overlapping portions of the fingers define an aperture of each acoustic resonator. Sometimes, each of the resonators has two dielectric strips that overlap the IDT fingers in first and second margins of the aperture and that extend into first and second gaps between the first and second margins and the busbars. Other times, the first and second dielectric strips are on the front surface of the plate, have a first portion under the IDT fingers and have a second portion extending into a gap between the margins and the busbars.
