  • Publication number: 20240120317
    Abstract: A fan-out semiconductor device includes stacked semiconductor dies having die bond pads arranged in columns exposed at a sidewall of the stacked semiconductor dies. The stacked dies are encapsulated in a photo imageable dielectric (PID) material, which is developed to form through-hole cavities that expose the columns of bond pads of each die at the sidewall. The through-hole cavities are plated or filled with an electrical conductor to form conductive through-holes coupling die bond pads within the columns to each other.

  • Patent number: 8158224
    Abstract: A housing (100, 300, 600, 700) for storing and protecting items comprises a photoreactive material (106) that selectively and irreversibly changes colors upon exposure to activating radiation (124, 324); and an ultraviolet attenuation coating (102, 702) disposed over the photoreactive material (106). Radiation (124, 324) is selectively applied to the photoreactive material (106) to irreversibly change the color of the photoreactive material (106) and therefore the housing (100, 300, 600, 700). An optional patterned layer (332) may be disposed between the photoreactive material (106) and the selective application of radiation (124, 324), and a background color (108) may be included, to affect the visual presentation of the housing (100, 300, 600, 700).

  • Publication number: 20080286352
    Abstract: A method of liposome-based therapy for a mammalian subject is disclosed. The method uses liposomes and/or liposomes with outer surfaces that contain an affinity moiety effective to bind specifically to a biological surface at which the therapy is aimed, and a hydrophilic polymer coating. The hydrophilic polymer coating is made up of polymer chains covalently linked to surface lipid components. After a desired liposome biodistribution is achieved, the affinity agent binds to the target surface and helps internalize the liposomes.

  • Patent number: 7390502
    Abstract: The present invention is for novel compositions and methods for treating diseases caused by cellular proliferation, particularly, for treating cancer in mammals and more particularly in humans. The therapeutic compositions of the present invention include SN-38 lipid complexes in which the complexes can contain any of a variety of neutral or charged lipids and, desirably, cardiolipin. The compositions are capable of efficiently incorporating SN-38 into complexes and are capable of solubilizing relatively high concentrations of SN-38.

  • Publication number: 20060030578
    Abstract: Delivering therapeutic amounts of irinotecan remains limited due to its highly water insoluble properties. This invention overcomes this limitation by presenting a novel method of preparing liposomal irinotecan by first inactivating irinotecan prior to liposome formation and then subsequently activating the irinotecan by lowering the pH of the lipid composition to an acidic pH of less than about 3.5, such as between 1.5-3.0 or about 2.
