Title: Multiple purpose quick-changeover extrusion system
Inventor: WENGER LAVON G
IPC: A23P1/12
Filed: 2001-03-22
Granted: 2002-02-21
Abstract: Improved, high-capacity extrusion systems (20, 220) are provided which minimize product losses and permit the user to conduct multiple, segregated short extrusion runs with a minimum of down time between runs. The systems (20, 220) include an extruder assembly (21, 221) having a special, multiple-position die assembly (28), as well as an upstream preconditioner (24) and feed bin assembly (22). A variable speed, variable output discharge screw feeder (78) is located between the preconditioner outlet (62) and extruder barrel inlet (90). A PLC-type controller (30) coupled to the extruder assembly components establishes a choke full condition at the discharge feeder (78) so that continuous uninterrupted flow of preconditioned material to the extruder (26) at a uniform mass flow rate is maintained for as long as possible. In preferred forms, load cells (46, 72) are operatively coupled to the bin assembly (22) and preconditioner (24) so as to monitor material flow through the systems (20, 220). A multiple stage cascade-type dryer assembly (29) is provided downstream of extruder (26). The assembly (29) is controlled via the controller (30) in coordination with the extruder assemblies (21, 221) so as to maintain the segregation between separate product runs throughout the drying operation.

Title: Multiple planar complex optical devices and the process of manufacturing the same
Inventor: PARIS BERTRAND
IPC: G02B6/24
Filed: 2001-06-06
Granted: 2005-03-11
Abstract: A method and structure for the mechanical and optical coupling of a plurality of individual planar optical devices (10, 20) to one another includes aligning the devices, bonding (35, 37, 38) the substrates (12, 22) of the planar devices (10, 20) to one another and subsequently fusing (40, 42, 44, 46) aligned optical waveguides (11, 29) utilizing a heat fusion technique. The substrates (12, 22) are bonded utilizing either heat fusion for a silica substrate or by a bonding adhesive for a silicon substrate. Once the aligned substrates (12, 22) have been mechanically bonded to one another, the optical pathways (11, 29) are coupled in one embodiment by heat fusion, preferably a focused CO2 laser (30) which completes the mechanical and optical interconnection of multiple devices. It is possible with such alignment, bonding, and fusion processes to couple numerous planar optical devices (10, 20, 50) in an array which can subsequently be packaged for use in relatively complex optical networks. The resultant devices display a high level of reliability, are relatively inexpensive to manufacture, and display excellent operating characteristics.

Title: Multi-chip semiconductor package structure and its manufacture process
Inventor: WU JI-CHIUAN
IPC: H01L23/28
Filed: 2001-07-23
Granted: 2002-07-01
Abstract: This invention provides multi-chip semiconductor package structure and its manufacture process. An elastic body is placed at a position higher than the arc apex of solder wire of the layer on the area near the central region of circuit plane of the top chip of a stacked multi-chip semiconductor module, which defines the safety margin between the upper mold and the arc apex of solder wire of top layer during the mold press process. Therefore, even if the substrate is wrapped due to thermal deformation, the elastic body will touch the upper mold surface and the substrate will be pressed and closely pasted onto the lower mold as the upper mold goes down, in which the solder wire on the chip layer will be not deformed by contacting the top mold and thus short or other damages will not occur. Moreover, the elastic deformation of the elastic body helps prevent damages of the top layer chip and the upper mold. Concurrently, the occurrence of flash is avoided as the substrate can be paste flatly onto the lower mold surface, which can obtain better product reliability and improve product yield.

Title: Method for making GaN MOSFET
Inventor: WANG YUNG-HE
IPC: H01L21/28
Filed: 2001-08-09
Granted: 2002-12-21
Abstract: The present invention relates to a method for producing a GaN MOSFET. A liquid phase deposition method is used to deposit an oxide layer on a GaN semiconductor. The oxidation system is rather effective and cheap. It only requires to insert a GaN chip in a mixture solution of hexafluorosilicic acid and boric acid in room temperature and an atmospheric pressure to form a silicon oxide layer. This deposition method will deposit the oxide layer on the chip without depositing on metal. Meanwhile, the property where a PEC wet etching does not etch SiO2 facilitates the use of silicon dioxide as a mask in platform etching. During the process, a rapid thermal annealing is used as a necessary thermal treatment to improve the quality of the oxide layer.
