  • Publication number: 20050199486
    Abstract: In a method of refurbishing a deposition target, a surface of the target is provided in a process zone. An electrical arc is generated in the process zone, and a consumable metal wire is inserted into the process zone to form liquefied metal. A pressurized gas is injected into the process zone to direct the liquefied metal toward the surface of the target to splatter the liquefied metal on the surface, thereby forming a coating having the metal on at least a portion of the surface of the target that exhibits reduced contamination from the environment.

  • Publication number: 20050204086
    Abstract: The invention is directed to a memory card that includes a device connector conforming to the memory card standard, and a host connector conforming to a host connection standard and comprising a retractable shieldless tab compatible with the host connection standard. The presence of the two connectors adds versatility to the memory card. The host connector facilitates direct coupling of the memory card to a computing device without an adapter or reader. The memory card maintains a form factor of the memory card standard when the shieldless tab is retracted, which allows the memory card to be used similar to a conventional memory card of the memory card standard. In order to fit within the memory card standard form factor, the shieldless tab may be an altered version of a conventional connector interface conforming to the host connection standard.

  • Publication number: 20050202720
    Abstract: A hermetic pressure connector which provides a pressure-tight, electrically conductive connection through a hole in a bulkhead. The connector includes a transverse support member having a high pressure side and an opposite low pressure side. A passage extends through the transverse support member between the opposite sides. A conductor pin having an axial portion extends through the passage. An insulating sleeve surrounds at least the axial portion of the conductor pin, thereby electrically insulating the transverse support member from the conductor pin. A molded connected body surrounds at least a central portion of the conductor pin at least at one of the high and low pressure sides to thereby mechanically support the conductor pin in the passage. The molded connector body is directly sealingly engaged with the conductor pin, the insulating sleeve and the transverse support member.

  • Publication number: 20050203842
    Abstract: Systems and methods are provided for processing transactions, and more specifically for receiving, processing and transmitting electronic payment transaction information. The system and method accesses a transaction software engine that effectuates the authorization of electronic payment requests and the settlement of authorized electronic payments. The transaction software engine, in accordance with an embodiment of the invention, resides at a merchant's site and more specifically within the merchant's server or computer which is in communication with one or more network terminals. With such a system, authorization requests may be sent by a terminal as each transaction occurs. Batches of settlement requests are processed after a predetermined time, although the transactions are processed on a transaction-by-transaction basis. In addition, the software engine enables the transmission of data over the Internet.

  • Publication number: 20050167799
    Abstract: A method of fabricating a chip-scale or wafer-level package having passivation layers on substantially all surfaces thereof to form a hermetically sealed package. The package may be formed by disposing a first passivation layer on the passive or backside surface of a semiconductor wafer. The semiconductor wafer may be attached to a flexible membrane and diced, such as by a wafer saw, to separate the semiconductor devices. Once diced, the flexible membrane may be stretched so as to laterally displace the individual semiconductor devices away from one another and substantially expose the side edges thereof. Once the side edges of the semiconductor devices are exposed, a passivation layer may be formed on the side edges and active surfaces of the devices. A portion of the passivation layer over the active surface of each semiconductor device may be removed so as to expose conductive elements formed therebeneath.

  • Patent number: 6914310
    Abstract: A method for forming a floating gate semiconductor device such as an electrically erasable programmable read only memory is provided. The device includes a silicon substrate having an electrically isolated active area. A gate oxide, as well as other components of a FET (e.g., source, drain) are formed in the active area. A self aligned floating gate is formed by depositing a conductive layer (e.g., polysilicon) into the recess and over the gate oxide. The conductive layer is then chemically mechanically planarized to an endpoint of the isolation layer so that all of the conductive layer except material in the recess and on the gate oxide is removed. Following formation of the floating gate an insulating layer is formed on the floating gate and a control gate is formed on the insulating layer.
