Title: Divided type optical fiber tape core wires
Inventor: SATO TOSHIHISA
IPC: G02B6/44
Filed: 1997-09-12
Granted: 2001-02-01
Abstract: In this invention, multi colored optical fibers are arranged in parallel. In addition, multi pieces of optical fiber tape core wires, which are formed into constitution by the whole-body covering resin, are arranged in parallel, where the whole-body covering resin is constituted by the UV curable resin. These optical fiber tape core wires are bonded to form the divided type optical fiber tape core wires by using the bonding resin constituted by the UV curable resin. The adhesion strength of the whole-body covering resin and the bonding resin ranges from 1 to 100 g/cm. The Young's modulus of the bonding resin after curing ranges from 5 to 100 kg/mm<2>. The elongation of the linking resin after curing ranges from 5 to 80%. Since the adhesion strength of the bonding resin and the whole-body covering resin are within the predetermined range, the dividing process of each optical fiber tape core wire can be performed without any problem. Additionally, it will not result in increase in transmission loss under the condition of humid hot or warm water environment. Furthermore, since the Young's modulus and the elongation of the bonding resin are within the predetermined range, the error of transmission signal during the dividing process and the dividing beyond the prediction during the cable process can be prevented. Therefore, the unpredicted dividing can be prevented and the difficulty of dividing can be eliminated.

Title: Undoped silicon dioxide as etch stop for selective etch of doped silicon dioxide
Inventor: KO KEI-YU
IPC: H01L21/768
Filed: 1998-02-16
Granted: 2002-10-21
Abstract: The present invention relates to a process for selectively plasma etching a structure upon a semiconductor substrate to form designated topographical structure thereon utilizing an undoped silicon dioxide layer as an etch stop. In one embodiment, a substantially undoped silicon dioxide layer is formed upon a layer of semiconductor material. A doped silicon dioxide layer is then formed upon said undoped silicon dioxide layer. The doped silicon dioxide layer is etched to create the topographical structure. The etch has a material removal rate that is at least 10 times higher for doped silicon dioxide than for undoped silicon dioxide or the semiconductor material. One application of the inventive process includes selectively plasma etching a multilayer structure to form a self-aligned contact between adjacent gate stacks and a novel gate structure resulting therefrom. In the application, a multilayer structure is first formed comprising layers of silicon, gate oxide, polysilicon, and tungsten silicide. An undoped silicon dioxide layer is formed over the multilayer structure. After patterning and etching, the multilayer structure to form gate stacks therefrom, a layer silicon nitride is deposited and is etched to create spacers on the gate stacks that are generally perpendicular to the silicon layer. Doped silicon dioxide is then deposited over the gate stacks and corresponding spacers. A photoresist layer is utilized to expose selective portions of silicon dioxide layer above the contacts on the silicon layer that are to be exposed by etching down through the doped silicon dioxide layer. The doped silicon dioxide is then selectively etched using an anisotropical plasma etch that utilizes a carbon fluorine etch. The novel gate structure comprising an undoped silicon dioxide cap is capable of resisting a carbon fluorine etch.

Title: Coating pot for coating metal strip with a zinc-containing metal and coating apparatus
Inventor: BOSTON STEVEN L
IPC: C23C2/00
Filed: 1998-11-23
Granted: 2001-10-21
Abstract: A zinc-coating pot for galvanizing steel strip has two levels along its bottom surface. The first, shallower level is located under a coating roll, thereby creating an area where the molten zinc-coating metal flow rate is relatively high. Dross particles remain suspended and do not accumulate on the bottom of the zinc-coating pot in this region. A second, deeper level is located to one side of the first level. This second level creates a space wherein the molten metal flow rate is less than the terminal velocity of the dross particles. This encourage sedimentation of the dross particles in this region. It provides an accumulation area for any bottom dross to be later removed by a dross removal mechanism, such as mechanical scoops or by pumping, without interruption to the coating process.

Title: Method of plasma etching doped polysilicon layers with uniform etch rates
Inventor: LEVERD FRANCOIS
IPC: H01L21/768
Filed: 1998-12-03
Granted: 2001-05-16
Abstract: In wafer semiconductor manufacture, a method of etching an arsenic doped polysilicon layer down to a patterned boro-phospho-silicate-glass (BPSG) layer provided with a plurality of openings with an uniform etch rate is disclosed. The method relies on a combination of both system and process improvements. The system improvement consists to hold the wafer in the reactor during the etch process with an electrostatic chuck device to have a perfect plasma environment around and above the wafer. On the other hand, the process improvement consists in the use of a non dopant sensitive and not selective chemistry. A NF3/CHF3/N2 gas mixture with a 11/8.6/80.4 ratio in percent is adequate in that respect. The etch time duration is very accurately controlled by an optical etch endpoint detection system adapted to detect the intensity signal transition of a CO line at the BPSG layer exposure. The process is continued by a slight overetching. When the above method is applied to the doped polysilicon strap formation in DRAM chips, excessive or insufficient etching of the polysilicon layer is avoided, so that the doped polysilicon strap thickness is thus much more uniform, opening to opening, within a wafer.

Title: Improved locking pin for excavating equipment
Inventor: KREITZBERG JOHN S
IPC: F16B21/12
Filed: 1998-12-18
Granted: 2000-07-11
Abstract: An improved locking pin for locking together two pieces of equipment through aligned locking apertures. The pin comprises a steel casing, a steel insert and an elastomer member. The two steel parts assemble together in a particular sequence and are adjusted so that when completely assembled, the insert is locked into the casing with the body of the casing and the insert being parallel and spaced from one another The elastomer member is interposed in the space defined between the casing and insert, and fills the space between the steel parts. The assembled steel parts are firmly locked together by introduction of the elastomer member into that space. There is no adhesive joining the steel and elastomer members which makes the pin more amenable for use in corrosive environments and also eases manufacture of the pin components. A tightly constructed locking pin also avoids the problems of the components becoming loose or lost.
