Title: Method for making intermetal dielectric layer
Inventor: TSAI JENG-YUAN
IPC: H01L21/3105
Filed: 2000-03-31
Granted: 2001-07-21
Abstract: A method for making an intermetal dielectric layer is applicable on a multiple metal interconnect. The method comprises providing a substrate formed with a metal wire; sequentially forming a first fluorinated silicon glass layer with a low fluorine content, a fluorinated silicon glass layer applied with a bias pressure and cooled with helium gas; applying a planarization process on the oxidation cover layer until the surface aligns in height with the fluorinated silicon glass layer with a low fluorine content. The fluorinated silicon glass layer applied with a bias pressure and cooled with helium gas is protected between two fluorinated glass layers with a low fluorine content, therefore it has a low water absorbency and a low activity with regard to the whole intermetal dielectric layer. Therefore, the present invention can avoid a metal corrosion, a self-degradation, and a delamination at the interface of the intermetal dielectric layer.

Title: Public cryptographic control unit and system therefor
Inventor: SPRAGUE STEVEN K
IPC: G06F21/12
Filed: 2000-05-16
Granted: 2002-02-01
Abstract: A universally available, public cryptographic control unit (crypto unit) is used in a cryptographic system shared by multiple independent users. The crypto unit, which is installed as a peripheral device to a general-purpose computer, loads and unloads encrypted security applets into an onboard RAM memory of the crypto unit, where each security applet is run. The crypto unit and the system of which it is a part, provides a secure internal environment in which only pre-approved security applets are granted permission to load and run. The computing environment within the crypto unit is secured by a cryptographic operation center (OPC) which communicates with each crypto unit. The software developer submits a proposed security applet to the OPC prior to distributing a given security applet in order to obtain the necessary permission for the given security applet. Only if all necessary permissions are obtained from the OPC will a given security applet be allowed to load and run in the crypto unit. When a first security applet is finished running, the crypto unit unloads (swaps out) the presently loaded first security applet in encrypted form to the PC hard drive, and loads (swaps in) the next security applet. The cryptographic context of each security applet is preserved in the file stored on the PC hard drive. In such manner, a single crypto unit is shared among a plurality of independent users.

Title: Infrared thermographic method for process monitoring and control of multilayer conductive compositions
Inventor: GOZDZ ANTONI S
IPC: G01N25/72
Filed: 2000-05-30
Granted: 2002-09-01
Abstract: An infrared thermographic camera is used to detect non-uniformities in the surface temperature of a multi-layer conductive composition comprising at least two electronically conductive layers separated by an electronically insulating layer. The temperature non-uniformities are caused by ohmic heating brought about by a flow of electrical current through a defect or defects in the electronically insulating layer when a predetermined voltage is applied to the two electronically conductive layers. The two electronically conductive layers may comprise the positive and negative electrode pair of an electrochemical device, such as a primary or rechargeable battery, supercapacitor, or electrochromic element, and the electronically insulating layer, which is superimposed between the two layers, may constitute the separator or electrolyte layer of the electrochemical device. One or more layers of the device may additionally comprise electronically insulating liquid components, which may be ionically conductive. The device may be tested 'as is', or it may be tested inside a thin, impermeable package. The method is particularly useful for process optimization and control during the fabrication of multi-layer bonded plastic batteries.

Title: Store buffer which forwards data based on index and optional way match
Inventor: HUGHES WILLIAM ALEXANDER
IPC: G06F9/38
Filed: 2000-08-09
Granted: 2003-08-21
Abstract: An apparatus includes a buffer configured to store information corresponding to store memory operations and circuitry to detect a load which hits one of the stores represented in the buffer. More particularly, the circuitry may compare the index portion of the load address to the index portions of the store addresses stored in the buffer. If the indexes match and both the load and the store are a hit in the data cache, then the load and store are accessing the same cache line. If one or more bytes within the cache line are updated by the store and read by the load, then the store data is forwarded for the load. In one embodiment, the circuitry speculatively forwards data if the load and store indexes match and the store is a hit in the data cache. Subsequently, when the load is determined to hit/miss in the cache, the forwarding is verified using the load's hit/miss indication. In set associative embodiments, the way in which the load hits is compared to the way in which the store hits to further verify the correctness of the forwarding.

Title: Method of applying a dry film resist to a printed circuit board and apparatus for the same
Inventor: KEIL CHARLES R
IPC: B29C65/02
Filed: 2000-08-25
Granted: 2003-02-11
Abstract: An improved method of and apparatus that is continuously automatically operative in an in-line system is described for applying under vacuum, heat and mechanical pressure a dry film photoresist-forming layer to printed circuit boards (200) that already have been prelaminated by the loose application thereto of the dry film resist as discrete cut sheets within the confines of the surface of the boards whereby a laminate without entrapped air bubbles and closely conforming to the raised circuit traces and irregular surface contours of the printed circuit board is obtained. Featured is a conveyorized vacuum applicator (12) comprising two independent vacuum lamination chambers (18, 20) in end-to-end relation. The first vacuum chamber operates at ambient temperature to draw off all of the air entrapped between the dry film resist and the surface of the printed circuit board at conditions that do not result in premature tacking of the dry film to the surface of the board. Then, in the second vacuum chamber, the photoresist-forming layer is immediately laminated to the printed circuit board under heat and mechanical pressure. The forgoing reduces or eliminates common lamination defects such as premature resist tacking and the attendant need to repair or rework the printed circuit board.
