Title: Method for manufacturing U shaped gate structure of a power transistor with low sheet resistance
Inventor: HUANG LIN-JUNG
IPC: H01L21/28
Filed: 2000-09-20
Granted: 2001-07-21
Abstract: A method for manufacturing U-shaped gate structure of a power transistor with low sheet resistance is disclosed. A dielectric material layer is formed on a semiconductor substrate and a first dielectric layer and a second dielectric layer are formed thereon. Next, a photoresist pattern layer is formed on the second dielectric layer to expose a portion to be etched. The exposed portion is etched and therefore the photoresist pattern is transferred on the first dielectric layer. An ion, which is a conductive dopant with the polarity identical to the dielectric layer, is doped into the exposed portion. The photoresist pattern layer is removed and a local oxidation process is performed to the wafer. Thereafter, the second and first dielectric layers are etched to expose the dielectric material layer. A U-shaped structure is formed on the surface of the dielectric material layer and a third dielectric layer and a conductive layer are formed thereon. The conductive layer is etched until the surface of the third dielectric layer is exposed and only the conductive layer filling up the U-shaped structure is retained. Therefore, the U-shaped gate structure of a power transistor is finished.

Title: Improved structure for prying with adjusted angle
Inventor: LIOU MAU-TANG
IPC: B25C5/02
Filed: 2000-10-06
Granted: 2002-07-01
Abstract: The present invention provides an improved structure for prying with an adjusted angle, which mainly improves over a conventional prying operation where the working space is limited. The invention comprises installing a groove on the handle, in which a positioning press plate is pivotally installed on the handle in the groove and is abutted by a spring. A prying head is pivotally installed on the lug of the handle. A plurality of positioning grooves are installed on the periphery of the pivotal part of the prying head matching the pressing part of the positioning press plate. Thus, when the working space is limited, the positioning press plate can be pressed so that the press part of the positioning press plate detaches from the positioning groove of the prying head, thereby adjusting the angle of the prying head. When the positioning press plate is released again, the adjusted angle can be positioned for a smooth operation. This is a simple, fast, practical and multifunctional design.

Title: Laser control loop with automatic adaptation to the monitoring signal polarity
Inventor: LEHR STEFFEN
IPC: H01S5/0683
Filed: 2000-11-30
Granted: 2002-02-01
Abstract: The invention relates to a method and a circuit arrangement for a laser control loop with automatic adaptation to the monitoring signal polarity. Use us made of a single-phase method which consists in that a signal produced by the monitor during the starting phase of the laser control loop is compared with a reference value, and in accordance with the result of the comparison the signal produced by the monitor is fed directly or inverted to the comparator for controlling the light power of the laser during the starting phase of the laser control loop. A signal is produced which initially feeds the comparator for controlling the light power the inverted monitoring signal, or directly feeds the monitoring signal, in a fashion always independent of the monitoring signal polarity, but dependent on the polarity of a reference value, and feeds it in a non-inverted fashion in the case of a monitoring signal running up to the reference value. The laser control loop circuit according to the invention ensures that the monitoring signal is fed with a fixed polarity to the first comparator before the reference value for controlling the light power is reached. This is achieved by virtue of the fact that the monitoring signal is fed to a comparator which compares the monitoring signal with a reference value which is smaller than the reference value for controlling the light power. In the case of a monitoring signal not running up to the first reference value, the comparator for controlling the light power still continues to be fed the inverted monitoring signal. The laser control loop is provided, for example, for controlling the light power of a laser in optical scanning systems for recording or reproducing information independently of the monitoring signal polarity and/or the polarity of the monitor diode of the laser.

Inventor: OHTA FUMIHITO
IPC: G06T7/00
Filed: 2000-12-27
Granted: 2002-07-11
Abstract: Provided are a failure analysis method with which it is able to prevent incorrect recognition of fail shapes and to recognize and classify fail shapes at high accuracy, and a recording medium for recording its program, as well as a method of deriving compression thresholds used in the failure analysis method, and a recording medium for recording its program. Specifically, a recognition rule is read (ST1), and a plurality of compressed FBMs, i.e., fail bit maps, are prepared (ST2). After selecting an inferior recognition object (ST3), a predetermined region is selected based on the setting of a fail size (ST4), and the fail rate in the predetermined region is calculated (ST5). Subsequently, under the fail rate condition and the condition as to whether an inferior recognition object is adjacent or not, the inferior recognition object is estimated (ST6), and the fail rates of the remaining compressed FBMs are calculated and normalized (ST7). The fail shape is distinguished by collating the fail rates of their respective compressed FBMs to the fail shape judgement rule.

Title: Multilayer ceramic capacitor and method for the manufacture thereof
Inventor: CHAZONO KOICHI
IPC: H01G4/12
Filed: 2001-02-13
Granted: 2003-04-21
Abstract: A multilayer ceramic capacitor includes sintered laminated bodies having a plurality of dielectric layers alternately stacked with a multiplicity of internal electrodes, and a pair of external electrodes electrically coupled to the internal electrodes. The dielectric layer is of sintered ceramic grains. The ceramic grains include a core portion surrounded by a shell portion or a solid solution. The ceramic grains contain additive elements such as acceptor elements and/or rare earth elements. The additive elements are non-uniformly distributed in the core and/or shell portion of the ceramic grain or in the solid solution. Such non-uniform distribution of the additive elements in ceramic grains promotes or facilitates the reoxidation process of the ceramic grains and also increases electrical resistance thereof. Accordingly, the operating life characteristics of the multilayer ceramic capacitors, especially those incorporating therein thin dielectric layers, can be improved. As a result, the thickness of dielectric layers can be further reduced and a greater number of dielectric layers can be used in forming multilayer ceramic capacitors, enabling miniaturization and large capacitance thereof to be achieved.

Title: Method for evaluation of reticle image using aerial image simulator
Inventor: SPENCE CHRISTOPHER A
IPC: G03F1/70
Filed: 2001-02-27
Granted: 2004-10-21
Abstract: A method of evaluating a wafer structure formation process includes extracting the outline of an actual mask pattern, and simulating a lithographic process using the actual mask pattern to obtain a simulated wafer structure (350'). The extracting the outline of the actual mask pattern may include, for example, imaging the actual mask (107) using a scanning electron microscope (SEM) (105). A second simulated wafer structure (350'') may also be obtained, by simulating the lithographic process using the ideal mask pattern design that was used in producing the actual mask pattern. Thus the relative contribution of mask pattern effects to overall wafer proximity effects may be evaluated by comparing the two simulated wafer structures. This information may then be used to generate optical proximity correction (OPC) mask designs which compensate for mask patterning errors and give better wafer performance.

Title: Multi-coordinate probe measurement appliance
Inventor: HAIMER FRANZ
IPC: G01B5/012
Filed: 2001-07-25
Granted: 2002-12-11
Abstract: A multi-coordinate probe measurement appliance is proposed, in which a probe lever (5) which is pre-stressed in a sprung manner to a rest position, is mounted in a housing (3) such that it can move along a measurement axis (7) and can pivot transversely with respect to the measurement axis (7). A coupling piece (25) is guided on a guide surface (23) of the housing (3) such that it can move in the direction of the measurement axis. The probe lever drives the coupling piece (25) via a coupling drive (31, 33) both during movement of the probe arm (5) in the direction of the measurement axis (7) and during deflection of the probe arm (5) in the direction of the measurement axis (7). A measurement device (21) detects the position of the coupling piece (25) with respect to the housing (3). The coupling piece (25) and the guide surfaces (23) form running surfaces for balls (65) of a ball bearing arrangement (27), in which the running surface of at least one of these components - coupling piece (25) and housing (3) - can be deflected elastically and transversely with respect to the running surface, and holds the balls (65) clamped in between the running surfaces without any play. The coupling piece (25) and/or the housing (3) are composed of aluminum or an aluminum alloy and are coated with a comparatively thin hard anodized layer, into which the balls (65) can form a raceway groove. Such a probe measurement appliance can be produced with comparatively wide production tolerances, and is nevertheless able to guide the coupling piece (25) such that it can move essentially without any play in the housing (3).
