Title: High efficiency line driver for high crest-factor signals such as DMT/ADSL signals
Inventor: DO GARY L
IPC: H04L27/00
Filed: 2002-02-20
Granted: 2004-03-11
Abstract: The present invention, generally speaking, achieves a highly efficient line driver for high crest-factor signals such as DMT/ADSL signals. In an exemplary embodiment, a digital signal produced by a digital signal processor or the like is processed by a sigma-delta modulator (SDM) to produce one or more binary signal pairs. The signals of a signal pair are low-pass filtered, if necessary, and applied across the winding of a transformer. The transformer has a single secondary winding connected to the line and may has as many primary windings as the number of signal pairs. The transformer may have a unity turns ratio or may have a turns ratio for accomplishing voltage step-up. For one signal pair, the number of possible resulting signals levels on the secondary side is three, for two signal pairs five, etc. Using more than two signal levels, it becomes possible to recreate from the digital signals the corresponding analog waveform with the required accuracy. The circuit requires only a single supply voltage, is inherently balanced and provides high-voltage DC isolation. In same instances, the recomposition may be accomplished by driving multiple switches into a common load, and the load can be a line transformer.

Title: Production method of III nitride compound semiconductor group, III nitride compound semiconductor element based thereon and III nitride compound semiconductor light emitting element
Inventor: NAGAI SEIJI
IPC: H01L21/205
Filed: 2002-03-22
Granted: 2003-08-21
Abstract: The subject of the present invention is to provide the III nitride compound semiconductor restricted in penetration dislocation and produced with a reduced step switching. The invented production method comprises: forming an epitaxy growth GaN layer 32 on a GaN layer 31 where no first mask 41m and second mask 42m are formed thereon, in which when its thickness is greater than the first mask 41m, the GaN layer 32 grows horizontally to cover the first mask 41m, and as there is no second mask 42m formed on top of the first mask 41m, it grows vertically. By contrast, on the GaN layer 31 where there is no first mask 41m formed, as the second mask 42m is formed in a mask eaves fashion, it stops growing. Meanwhile, the penetration dislocation transports along the vertical growth stops there. On top of the first mask 41m, the GaN layer 32 grows along the portion of the second mask 42m where the penetration is not yet formed. When its height exceeds the top of the second mask 42m, the GaN layer 32 once again grows horizontally and covers the second mask 42m. Once the top of the second mask 42m is fully covered with the GaN layer 32, epitaxy grows continues.

Title: Chemical mechanical polishing process
Inventor: SHIU JIA-LIN
IPC: H01L21/304
Filed: 2002-07-12
Granted: 2004-05-11
Abstract: A CMP process includes adding a chemical reagent into a barrier layer slurry to form a metal layer slurry, meanwhile using the addition or not of the chemical reagent to adjust the properties of the slurry in order to be separately used for removal of the metal layer and the barrier layer. Thus, tedious steps in cleaning a polishing pad in a conventional polishing process can be removed, while avoiding problems such as pH shock caused by differences in the slurry and the defects formed on the device derived therefrom.

Title: Laser irradiation method, laser irradiation apparatus, and method of manufacturing a semiconductor device
Inventor: TANAKA KOICHIRO
IPC: H01S3/00
Filed: 2002-08-08
Granted: 2007-04-11
Abstract: Attenuation regions of laser light are removed or reduced in size using a slit located in the immediate vicinity of a surface to be irradiated so that a steep energy distribution is obtained in the end portions of the laser light. The reason why the slit is located in the immediate vicinity of the surface to be irradiated is to suppress the spread of the laser light. In addition, the attenuation regions of the laser light are folded by using a mirror instead of the slit to increase energy densities in the attenuation regions by one another so that a steep energy density distribution is obtained in the end portions of the laser light.

Patent TW-I289247-B (TW)
Title: A method for generating a random number and a random number generator
Inventor: WEIMERSKIRCH ANDRE
IPC: G06F1/02
Filed: 2002-11-19
Granted: 2007-11-01
Abstract: A method and apparatus are disclosed for preventing noise from influencing a random number generator that is based on the meta-stable behavior of flip-flops. External noise will affect multiple flip-flops in a larger random number generator circuit in the same way, since they are physically close. Thus, the ability to influence the operation of a random number generator using external noise is reduced by incorporating a plurality of flip-flops, referred to herein as core random elements, in a single random number generator. If one of the core random elements in a random number generator is influenced by noise, all of the core random elements will be influenced by the noise. Thus, if all (or most) of the core random elements issue a random bit at the same time, there is a possibility that the random number generator was influenced by noise, and all the issued bits are discarded. One or more mechanisms are incorporated into the random number generator to ensure that a random bit is not generated when a plurality of the core random elements generate a bit at the same time.

Title: Method of forming resist pattern
Inventor: YAMASHITA MASAMI
IPC: G03F7/40
Filed: 2003-03-17
Granted: 2004-09-01
Abstract: A method of forming a resist pattern effectively controls the manner/style and the amount of modification of a resist pattern in its reflowing process, realizing a desired resist pattern with a desired accuracy even if the deformation amount of the resist pattern is increased in the reflowing process. A second layer is formed on a first layer and then, a first resist pattern is formed on the second layer. The second layer is selectively etched using the first resist pattern as a mask. Thereafter, wettability of at least part of an exposed area of the second or first layer from the first resist pattern is adjusted, thereby forming a wettability-adjusted part. The first resist pattern is modified in such a way as to extend to the wettability-adjusted area by reflowing the first resist pattern using an organic solvent, thereby forming a second resist pattern for selectively etching the first layer or the second layer.

Title: Method of chamfering semiconductor wafer
Inventor: NAKAYAMA MASAHIRO
IPC: B24B9/06
Filed: 2003-07-29
Granted: 2006-02-21
Abstract: Technology of making freestanding gallium nitride (GaN) wafers has been matured at length. Gallium nitride is rigid but fragile. Chamfering of a periphery of a GaN wafer is difficult. At present edges are chamfered by a rotary whetstone of gross granules with weak pressure. Minimum roughness of the chamfered edges is still about Ra 10 mum to Ra 6 mum. The large edge roughness causes scratches, cracks, splits or breaks in transferring process or wafer process. A wafer of the present invention is bevelled by fixing the wafer to a chuck of a rotor, bringing an edge of the wafer into contact with an elastic whetting material having a soft matrix and granules implanted on the soft matrix, rotating the wafer and feeding the whetting material. Favorably, several times of chamfering edges by changing the whetting materials of smaller granules are given to the wafer. The chamfering can realize small roughness of Ra 10 nm and Ra 5 mum at edges of wafers.
