Patent application numberDescriptionPublished
20080289766Hot edge ring apparatus and method for increased etch rate uniformity and reduced polymer buildup - An apparatus with an edge ring configured to surround a perimeter of a semiconductor wafer in a semiconductor process, the edge ring having a plurality of protrusions located on an upper surface of the edge ring, the protrusions capable of preventing the semiconductor wafer from moving outside the bounds of a process plane. There is also an apparatus having a semiconductor process chamber and an electrostatic chuck, a semiconductor wafer, and an edge ring. There is also a method including providing a semiconductor process chamber, semiconductor wafer disposed within the semiconductor process chamber, and an edge ring, the edge ring having a plurality of protrusions located on an upper surface of the edge ring, the protrusions capable of preventing the semiconductor wafer from moving outside the bounds of a process plane. The method also includes performing an etch process on the semiconductor wafer.11-27-2008

20100278905STABILIZED LIPID FORMULATION OF APOPTOSIS PROMOTER - An orally deliverable pharmaceutical composition comprises a Bcl-2 family protein inhibitory compound, e.g., ABT-263, a heavier-chalcogen antioxidant and a substantially non-aqueous lipid carrier, wherein said compound and said antioxidant are in solution in the carrier. The composition is suitable for oral administration to a subject in need thereof for treatment of a disease characterized by overexpression of one or more anti-apoptotic Bcl-2 family proteins, for example cancer.11-04-2010
20100278921SOLID ORAL FORMULATION OF ABT-263 - An orally deliverable pharmaceutical composition comprises (a) a pharmaceutically acceptable acid addition salt of ABT-263 in solid particulate form, and (b) a plurality of pharmaceutically acceptable excipients including at least a solid diluent and a solid disintegrant; wherein the salt is formed from more than one equivalent of acid per equivalent of ABT-263. The composition is suitable for oral administration to a subject in need thereof for treatment of a disease characterized by overexpression of one or more anti-apoptotic Bcl-2 family proteins, for example cancer.11-04-2010
20100280031LIPID FORMULATION OF APOPTOSIS PROMOTER - An orally deliverable pharmaceutical composition comprises a drug-carrier system having a Bcl-2 family protein inhibitory compound, e.g., ABT-263, in solution in a substantially non-aqueous carrier that comprises at least one phospholipid and a pharmaceutically acceptable solubilizing agent. The composition is suitable for oral administration to a subject in need thereof for treatment of a disease characterized by overexpression of one or more anti-apoptotic Bcl-2 family proteins, for example cancer.11-04-2010
20100297194FORMULATION FOR ORAL ADMINISTRATION OF APOPTOSIS PROMOTER - An orally deliverable pharmaceutical composition comprises as a sole or first active ingredient a compound of Formula I defined herein or a pharmaceutically acceptable salt thereof, for example ABT-263 free base or ABT-263 bis-HCl salt, dispersed, in a free base equivalent amount of at least about 2.5% by weight of the composition, in a pharmaceutically acceptable carrier; wherein said active ingredient is in solid-state form and/or the composition further comprises, dispersed in the carrier, a pharmaceutically acceptable heavier-chalcogen antioxidant in an amount effective to inhibit oxidation of the active ingredient at a thioether linkage thereof. The composition is suitable for oral administration to a subject in need thereof for treatment of a disease characterized by overexpression of one or more anti-apoptotic Bcl-2 family proteins, for example cancer.11-25-2010
20100311751SOLID DISPERSIONS CONTAINING AN APOPTOSIS-PROMOTING AGENT - A pro-apoptotic solid dispersion comprises, in essentially non-crystalline form, a Bcl-2 family protein inhibitory compound, e.g., ABT-263, dispersed in a solid matrix that comprises (a) a pharmaceutically acceptable water-soluble polymeric carrier and (b) a pharmaceutically acceptable surfactant. A process for preparing such a solid dispersion comprises dissolving the compound, the polymeric carrier and the surfactant in a suitable solvent, and removing the solvent to provide a solid matrix comprising the polymeric carrier and the surfactant and having the compound dispersed in essentially non-crystalline form therein. The solid dispersion is suitable for oral administration to a subject in need thereof for treatment of a disease characterized by overexpression of one or more anti-apoptotic Bcl-2 family proteins, for example cancer.12-09-2010
