Patent number: 8390109Abstract: In a chip package, semiconductor dies in a vertical stack of semiconductor dies or chips (which is referred to as a ‘plank stack’) are separated by a mechanical spacer (such as a filler material or an adhesive). Moreover, the chip package includes a substrate at a right angle to the plank stack, which is electrically coupled to the semiconductor dies along an edge of the plank stack. In particular, electrical pads proximate to a surface of the substrate (which are along a stacking direction of the plank stack) are electrically coupled to pads that are proximate to edges of the semiconductor dies by an intervening conductive material, such as: solder, stud bumps, plated traces, wire bonds, spring connectors, a conductive adhesive and/or an anisotropic conducting film. Note that the chip package may facilitate high-bandwidth communication of signals between the semiconductor dies and the substrate.Type: GrantFiled: February 17, 2011Date of Patent: March 5, 2013Assignee: Oracle America, Inc.Inventors: Darko R. Popovic, Matthew D. Giere, Bruce M. Guenin, Theresa Y. Sze, Ivan Shubin, John A. Harada, David C. Douglas, Jing Shi

Patent number: 6860588Abstract: A printhead for an inkjet printer having geometric features which reduce drop placement error of main and satellite drops ejected from the nozzles of the printhead. Nozzles that are tilted along an axis corresponding to the direction of scanning of the printhead while printing have reduced drop placement error in the orthogonal direction to the scanning, and create a breakoff velocity for the satellite drop that can cause the main and satellite drops to be placed in a coincident location on the medium in one of the directions of scanning, thus forming desireable round printed spots and reducing drop placement error in the scan direction. These improvements can be repeatably achieved for all nozzles. Nozzles with non-circular and asymmetric bores also reduce drop placement errors, particularly when these types of nozzles are also tilted.Type: GrantFiled: October 11, 2000Date of Patent: March 1, 2005Assignee: Hewlett-Packard Development Company, L.P.Inventors: Clayton L Holstun, Jeffrey Allen Nielsen, Matthew D Giere, Scott Norum, Stephen W Bauer, Mark D Lund, Robert W Sperry, Dustin W Blair

Patent number: 6746107Abstract: An inkjet printhead includes a substrate having an ink feed slot formed therein. The inkjet printhead includes drop generators and ink feed channels. Each drop generator has a nozzle and a vaporization chamber. At least one ink feed channel is fluidically coupled to each vaporization chamber and is fluidically coupled to the ink feed slot. A thin-film structure is supported by the substrate and defines a first portion of each ink feed channel. An orifice layer supported by the substrate defines the nozzles and the vaporization chambers in the drop generators. The orifice layer defines a second portion of each ink feed channel.Type: GrantFiled: October 31, 2001Date of Patent: June 8, 2004Assignee: Hewlett-Packard Development Company, L.P.Inventors: Matthew D.
