  • Patent number: 7208839
    Abstract: Methods relating to forming interconnects through injection of conductive materials, to fabricating semiconductor component assemblies, and to resulting assemblies. A semiconductor component substrate, such as a semiconductor die or other substrate, has dielectric material disposed on a surface thereof, surrounding but not covering interconnect elements, such as bond pads, on that surface. A second semiconductor component substrate, such as a carrier substrate with interconnect elements such as terminal pads, is adhered to the first semiconductor component substrate, forming a semiconductor package assembly having interconnect voids between the corresponding interconnect elements. A flowable conductive material is then injected into each interconnect void using an injection needle that passes through one of the substrates into the interconnect void, forming a conductive interconnect between the bond pads and terminal pads of the substrates.

  • Patent number: 7163869
    Abstract: A STI (shallow trench isolation) structure is formed with a liner layer that is converted from an initial material to a subsequent material. For example, the liner layer is initially comprised of nitride during wet etch-back of a dielectric fill material comprised of oxide to protect an oxide layer on a semiconductor substrate. Thereafter, an exposed portion of the liner layer is converted into the subsequent material of oxide to protect the dielectric fill material within the STI opening during etching away of masking layers to prevent formation of dents in the STI structure.

  • 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.
