Patent TW-221037-B (TW)
Title: Permanent metallic bonding method
Inventor: BACON DONALD DINGLEY
IPC: H01S5/02218
Filed: 1993-04-10
Granted: 1994-02-11
Abstract: A laser device is bonded to a diamond submount (20) by means of a procedure including (1) condepositing an auxiliary layer (22), on a layer of barrier metal (21) that has been deposited overlying the submount, followed by (2) depositing a wetting layer (23) on the auxiliary layer, and (3) by depositing a solder layer (24) comprising alternating metallic layers, preferably of gold and tin sufficient to form an overall tin-rich gold-tin eutectic composition. The barrier metal is typically W, Mo, Cr, or Ru. Prior to bonding, a conventional metallization such as Ti-Pt-Au (three layers) is deposited on the laser device's bottom ohmic contact, typically comprising Ge. Then, during bonding, the solder layer is brought into physical contact with the laser device metallization under enough heat and pressure, followed by cooling, to form a permanent joint between them. The thickness of the solder layer is advantageously less than approximately 5熤. The wetting layer is preferably the intermetallic compound Ni3Sn4, and the auxiliary layer is formed by codepositing the metallic components of this intermetallic together with the barrier metal.

Title: Coordination and synchronization of an asymmetric single-chip, dual multiprocessor and method for operating a multiprocessor a multiprocessor for coordination or synchronization of individual program instructions
Inventor: MOHAMED MOATAZ A
IPC: G06F15/80
Filed: 1997-08-19
Granted: 1999-08-11
Abstract: An integrated multiprocessor architecture simplifies synchronization of multiple processing units. The multiple processing units constitute a general-purpose processor and a vector processor which has a single-instruction-multiple-data (SIMD) architecture so that multiple parallel processing units in the vector processor all complete an instruction simultaneously and do not require software synchronization. The general-purpose processor controls the vector processor and creates a fork in a program flow by starting the vector processor. The two processors then execute separate program threads in parallel until the control processor stops the vector processor, an exception is encountered, or the vector processor completes its program thread and enters an idle state. A register coupled to and accessible by both processors stores a state bit indicating whether the vector processor is running or idle. The general processor can synchronize the separate program threads by executing a loop polls the state bit. When the state bit indicates the vector process is idle, the general-purpose processor can process results from the vector processor and restart the vector processor.

Title: Manufacturing method of liquefied carbon fuel and the apparatus therefor
Inventor: ITO MAMORU
IPC: C10L1/32
Filed: 1997-10-20
Granted: 1999-12-01
Abstract: This invention relates to a method of manufacturing liquefied carbon fuel and the apparatus therefor. Under this invention, it can generate carbonaceous material with relatively high carbon content. Through a process of atomization using a special type of nozzle, liquefied carbon material is converted to mist, which are then passed through a flame or heating element at high-temperature for continuous combustion. Hence, this material can be a source of energy and a substitute for crude oil. This is done by first burning organic material cryogenically in a closed chamber with no oxygen by means of indirect heating, which causes it to decompose under the heat and to generate carbonaceous materials, treating it with atomization, and then mixing it with prescribed proportion of water. It becomes liquefied carbon fuel.

The pellicle membrane is then placed over the adhesive covered frame, and a laser is used to bond the membrane to the frame. An additional, optional step to this process involves application of the laser to the outer edge of the pellicle membrane after the membrane is mounted to the pellicle frame to trim off excess membrane.
