Title: Production method for ferrules
Inventor: OKAMOTO SHINICHI
IPC: C25D1/02
Filed: 2001-01-12
Granted: 2004-01-01
Abstract: This invention provides a production method for ferrules, which uses one or a plurality of metal or plastic line(s) (9) as a master block and removes the line(s) (9) after electrocasting, characterized in that the line(s) (9) is electrocast by being rotated with its linear lengthwise direction kept.

Title: Method for removing residual polymer after the dry etching process and reducing oxide loss
Inventor: CHEN CHUNG-TAI
IPC: H01L21/306
Filed: 2001-05-17
Granted: 2004-08-11
Abstract: This invention discloses a novel manufacturing method of a semiconductor device. First of all, a photoresist layer is formed to cover the oxide layer located on the memory array and a photoresist layer on the oxide layer defining the periphery circuit. The oxide layer and the conductor layer of the periphery circuit region are etched by way of a dry etching process that uses the photoresist layer as an etching mask until the substrate on the periphery circuit region is exposed. A polymer protection layer will be formed on the etched sidewalls after the dry etching process, so as to keep the etching profile. After removing the photoresist layer, a standard clean 1 (SC1) of a wet etching process using an ultra dilute hydrofluoric acid (UDHF) or a low temperature ammonia peroxide mixture (APM) is then performed to strip the polymer protection layer of the polymer, so as to avoid any oxide loss.

Title: Semiconductor device
Inventor: KUMAGAI YUKIHIRO
IPC: H01L21/8238
Filed: 2001-12-06
Granted: 2003-01-21
Abstract: The present invention provides a semiconductor device including n-channel field effect transistors and p-channel field effect transistors all of which have excellent drain current characteristics. In a semiconductor device including an n-channel field effect transistor and a p-channel field effect transistor, a stress control film covering a gate electrode of the n-channel field effect transistor undergoes film stress mainly composed of tensile stress. A stress control film covering a gate electrode of the p-channel field effect transistor undergoes film stress mainly caused by compression stress compared to the film of the n-channel field effect transistor. Accordingly, drain current is expected to be improved in both the n-channel field effect transistor and the p-channel field effect transistor. Consequently, the characteristics can be generally improved.

Title: Disk clamp device
Inventor: WATANABE TAKASHI
IPC: G11B17/028
Filed: 2001-12-13
Granted: 2003-09-01
Abstract: This invention intends to prevent the deformation on the inner periphery of a disk due to the clamping force applied thereon. Also, it intends to assure the stability and surface accuracy of a disk upon being clamped. In the disk clamp device 23 according to this application, a friction member 42 attached to the disk supporting surface 18a of a clamp table 18 extends inwards to make its inner surface approximately flush with the inner surface of the disk 22. Besides, a clamper top member 34 extends radially outwards from its outer periphery to form a collar 34a under the innermost portion of the friction member 42. The top plane of the collar 34a is formed to be flush with the disk supporting surface 18a. Thus, the friction member 42 is supported in a completely planar state from the position opposing the innermost portion of the disk 22 to the vicinity of the outer periphery of the disk supporting surface 18a. Consequently, it is possible to prevent the downward deformation of the inner periphery of the disk 22, even if the front end 38a1-38e1 of the clamp member 38a-38e urge against the inner periphery of the disk 22 slantingly downwards under the action of the coil spring 36. In the disk clamp device 23, the clamp members 38a-38e and the aligners 40a-40e are equally spaced and alternately arranged along the outer periphery of the clamper top member 34 by a 72 degrees spacing, respectively. Besides, each one of the clamp members 38a-38e is arranged at a position diametrically opposed to one of the aligners 40a-40e. Whenever a clamping force of each of the clamp members 38a-38e acts on the inner periphery of the central hole of the disk 22, a counter clamping force will be given to the corresponding one of the aligners 40a-40e diametrically opposed to the clamp member. Thus, it is possible to stably and smoothly complete the aligning action and clamping motion of the disk 22. Further, it is also possible to reduce the spacing between adjacent clamp forces acting on the inner periphery of the central hole of the disk 22, so as to assure the stability and surface accuracy of the inner periphery of the central hole of the disk 22.
