  • Patent number: 5790728
    Abstract: An optical component (40) is formed by bonding a light generating device (43) onto a transparent substrate (41). The light generating device can be attached to the transparent substrate (41) using a flip-chip bond. A light detecting device (51) is also bonded to the transparent substrate (41) and positioned so that a portion of the optical signal provided by the light generating device (43) is reflected to the light detecting device (51) through the transparent substrate (41). A holographic film (42) may be formed on the transparent substrate (41) to diffuse the optical signal provided by the light generating device (43).

  • Patent number: 5590232
    Abstract: An optical package including a housing defining a mounting area with leads formed in the housing each having a first end in the mounting area and a second end external to the housing. A semiconductor die with photonic devices thereon is mounted in the mounting area and electrically connected to the leads. The active light areas of the photonic devices is accessible through the mounting area. Optical fiber alignment structure is mounted in the mounting area for receiving optical fibers and aligning the optical fibers with the active light areas of the photonic devices.

  • Patent number: 5477084
    Abstract: A method for manufacturing a liquid-containing microelectronic device package. The method includes steps of providing (32) a base (16) including a microelectronic device (22) and a seal area disposed peripherally about the base (16), providing (34) a lid (12) and providing (34) a sealant (14) disposed between the base (16) and lid (12). The method also includes steps of immersing (36) the base (16), sealant (14) and lid (12) in a liquid (24) having a temperature above a sealant activation temperature and maintaining (38) the base (16), sealant (14) and lid (12) in the liquid (24) for a time sufficient to allow the liquid (24) to enter between the base (16) and lid (12) and to heat and thereby activate the sealant (14). The method further includes removing (40) the base (16), lid (12) and sealant (14) from the liquid (24) to provide a sealed, liquid-containing microelectronic device package (10).

  • Patent number: 4818821
    Abstract: A brazed leaded package is provided having buried brazed areas thereby eliminating the need of subsequent protective plating of the brazed areas. The package has a heat conductive support which supports a plurality of leads. The distal end of the leads terminate on the top of the heat conductive support in a braze pad to which are brazed formed leads for providing interface connection to a semiconductor integrated circuit contained within the package. The package can be sealed by using a solid ceramic cover having a glazed glass on its bottom side which is heated up to reflow and provide the seal.

  • Patent number: 4184189
    Abstract: An inexpensive glass capacitive pressure sensor. Conductive capacitor electrodes are disposed on two flat glass plates, one serving as a diaphragm, the other as a substrate. The electrodes are positioned in a spaced apart, substantially parallel relationship to form the plates of a parallel plate capacitor. The glass plates are sealed together with a sealing glass mixture to bound a volume between the conductors. The volume is at a reference pressure, preferably a substantial vacuum. Differences between the pressure to be measured and this reference pressure cause a flexing of the glass diaphragm which is detected by measuring the capacitance between the two electrodes. A suitable sealing glass mixture which provides a hermetic seal between the glass plates is comprised of, in weight percent, 8-10 SiO.sub.2, 1-2 Al.sub.2 O.sub.3, 55-60 PbO, 7-9 PbF.sub.2, 7-10 ZnO, 4-6 CdO, and 10-15 B.sub.2 O.sub.3. The sealing glass mixture must be vacuum fined to permit hermetic sealing within a vacuum.
