  • Patent number: 7501227
    Abstract: A method for producing a pattern on a substrate includes providing at least one exposure of the pattern onto a layer of the substrate by a higher-precision lithography mechanism and providing at least one exposure of the pattern onto a layer of the substrate by a lower-precision lithography mechanism. The exposures can be done in either order, and additional exposures can be included. The higher-precision lithography mechanism can be immersion lithography and the lower-precision lithography mechanism can be dry lithography.

  • Publication number: 20080286938
    Abstract: A method for packaging a semiconductor device disclosed. A substrate comprising a plurality of dies, separated by scribe line areas respectively is provided, wherein at least one layer is overlying the substrate. A portion of the layer within the scribe lines area is removed by photolithography and etching to form openings. The substrate is sawed along the scribe line areas, passing the openings. In alternative embodiment, a first substrate comprising a plurality of first dies separated by first scribe line areas respectively is provided, wherein at least one first structural layer is overlying the first substrate. The first structural layer is patterned to form first openings within the first scribe line areas. A second substrate comprising a plurality of second dies separated by second scribe line areas respectively is provided, wherein at least one second structural layer is overlying the substrate. The second structural layer is patterned to form second openings within the second scribe line areas.

  • Publication number: 20080258309
    Abstract: A three-dimensional semiconductor device using redundant bonding-conductor structures to make inter-level electrical connections between multiple semiconductor chips. A first chip, or other semiconductor substrate, forms a first active area on its upper surface, and a second chip or other semiconductor substrate forms a second active area on its upper surface. According to the present invention, when the second chip has been mounted above the first chip, either face-up or face-down, the first active area is coupled to the second active area by at least one redundant bonding-conductor structure. In one embodiment, each redundant bonding-conductor structure includes at least one via portion that extends completely through the second chip to perform this function. In another, the redundant bonding-conductor structure extends downward to the top level interconnect. The present invention also includes a method for making such a device.

  • Patent number: 5200393
    Abstract: Methods and compositions are described for liquid or gel forms of a lipid excipient to be used in pharmaceutical or cosmetic preparations. The lipid excipient comprises a phospholipid such as a lysophospholipid, for example, mono-oleoyl-phosphatidylethanolamine ("MOPE"). Relatively low concentrations of the lipid can be employed in forming the gel, e.g., about 1-2%. The invention discloses the use of a lipid delivery system at a relatively low lipid concentration as a non-toxic, non-irritating carrier or excipient alone or in combination with other agents, for both drugs and cosmetics. For example, the lipid excipient in sprayable or droppable form has special utility in the non-irritating delivery of peptides (e.g., calcitonin and insulin) to the nasal mucosa, due to the ability of the excipient to enhance absorption across nasal membranes. As a cosmetic, it can be used alone or in combination with biologically active agents.
