Title: Method for forming pillar-shaped capacitor in memory device
Inventor: LIN KUEN-YOU
IPC: H01L27/108
Filed: 1999-12-13
Granted: 2001-06-16
Abstract: This invention is about the method for forming pillar-shaped capacitor in memory device. At first, a semiconductor substrate is provided and the first dielectric layer is formed on the semiconductor substrate. The first dielectric layer has a contact window opening, in which doped polysilicon is used to fill up the contact window opening to form a conduction plug. Then, the second dielectric layer is formed on the surface of the first dielectric layer and the conduction plug. A silicon-oxynitride layer is formed on the second dielectric layer and is followed by forming a photoresist layer on the silicon-oxynitride layer. After that, parts of the silicon-oxynitride layer and the second dielectric layer are etched. Then, an amorphous silicon layer is flatly and uniformly formed to cover the surface of silicon-oxynitride layer, the first dielectric layer, conduction plug and sidewall of pillar. The third dielectric layer is formed on the amorphous silicon layer. The third dielectric layer and part of amorphous silicon layer on the silicon-oxynitride layer are etched back. The amorphous silicon layer is processed to form a hemispherical grain on the surface of amorphous silicon layer. The silicon-oxynitride layer is removed. Finally, dipping process is performed onto the surface of the second dielectric layer so as to completely clean away the surface and protect the hemispherical grain layer, which is located on the pillar-shaped capacitor and has no need of connection. Therefore, the pillar-shaped capacitor is made to have no hemispherical grain layer.

Title: Door fastening device
Inventor: COWPER BRIAN EDWARD
IPC: E05C9/18
Filed: 2001-06-06
Granted: 2002-07-01
Abstract: A door fastening device for securement at a jamb (10) of the frame of said door (11), the device having a casing with a slot (43) in a recessed central part of a front face (38) thereof at which is disposed a faceplate (40) adjustably secured to the casing and having a slot (47) aligned with slot (43) to allow passage of a bolt (13) of a lock (12) or latch of the door. The bolt is arranged, when extended, to engage and move rearwardly in the casing a cam (24) secured to one side of a link (23) which is pivotally mounted at its respective ends to swivel bolts (21). The rearwards movement of the link (23) causes the bolts to extend through respective openings in the front of the casing to prevent opening of the door. The cam has a flat surface (29; 31) and at 90DEG thereto an arcuate nose surface (36), the cam being adjustably rotatable to position the flat surface or the nose surface in line with the bolt. Since the nose surface is radially further from the cam rotation axis than the flat surface, the adjustment compensates for differing gaps between the door and frame by ensuring the bolt always moves the link fully to its position where it causes both swivel bolts fully to extend.

Title: Method for peak value detection and focus jumping for compact disk drive
Inventor: SUEN YU-HUNG
IPC: G11B7/00
Filed: 2001-06-20
Granted: 2003-08-01
Abstract: The present invention provides a method for peak value detection and focus jumping for compact disk drive, which includes the following steps. First, the compact disk drive is located in the closed-loop control system, and the laser is stably focused on the layer 0 of reflective layer. Then, it is switched to the open-loop control system and a focus kick voltage is outputted, and the focus point will start moving away from the layer 0 of reflection layer to decrease the focus error signal toward the negative direction. When the focus point is located between the layer 0 of reflective layer and the layer 1 of reflective layer, the focus error signal will start increasing toward the positive direction until the focus error reaching 0. Then, the focus point approaches the layer 1 of reflective layer and outputs a focus brake voltage to reduce the speed until the focus error reaches the peak value in the positive direction. Then, the opened-loop control system is switched to the closed-loop control system for stably locking the focus point on the layer 1 of reflective layer, so as to increase the stability of focus jumping.
