Patent TW-392340-B (TW)
Title: DRAM structure and method for manufacturing the same
Inventor: LIN KUEN-JI
IPC: H01L27/108
Filed: 1998-08-27
Granted: 2000-06-01
Abstract: The present invention relates to a DRAM structure and its manufacturing method. The DRAM structure is formed by first forming transistors on a semiconductor substrate. Next, bit lines are formed on the semiconductor substrate. The bit line is electrically connected to the transistor via a contact window. Next, a second dielectric layer is formed on the bit lines, and an opening for the node contact window is formed on the second dielectric layer. Then, an etching step is executed to etch off the bit line toward an inner end until a side recess is defined in the side wall of the bit line. Further, a spacer is formed on the side wall of opening of the node contact window for fully covering the side recess. This spacer is able to provide the bit line with good insulation capability thereby allowing the node contact window to partially overlap with the bit line. Finally, an etching is executed to etch a first dielectric layer for exposing the semiconductor substrate, so as to define an opening for the storage node, and form a capacitor structure in the storage node opening.

Title: A polysilicon-to-polysilicon capacitor suitable for embedded nonvolatile memory in anglong application
Inventor: LIU LIAN-YI
IPC: H01L27/115
Filed: 1998-10-21
Granted: 2000-09-11
Abstract: An improved process for making embedded non-volalite memory cells is disclosed to eliminate the peel-off problem happening between the metal silicided bottom electrode and capacitor dielectric. One of the key characteristics of the improvements is that the second polysilicon (i.e., poly 2) is processed into two portions, one portion is silicided to form the control gate for the split-gate or stacked-gate memory; whereas, the other portion of the poly 2 is not silicided so as to form the bottom electrode for the embedded capacitor. Because the portion of the poly 2 constituting the bottom electrode of the capacitor is not silicided (i.e., does not contain a metal silicide layer on top thereof), the material incompatibility problem between the metal silicide layer and the capacitor dielectric which often causes the capacitor dielectric to be peeled off, is eliminated. Another characteristic of the improved process is that the poly 3 layer, which is deposited after the deposition of the poly 2, is patterned before the poly 2 layer, so as to allow the metal silicide layer to be formed only desired portion of the poly 2 layer.

Title: Engine balance shafts supporting structure
Inventor: NIIZATO TOMONORI
IPC: F02B75/20
Filed: 1999-08-11
Granted: 2000-08-21
Abstract: A casing accommodating therein a pair of balance shafts below the cylinder block comprises an upper casing and a lower casing that can vertically be split, and an oil pump body is molded integrally with one of the upper and lower casings. In addition, one end of each of the two casings is inserted into the oil pump body for support therein, and the two balance shafts are each supported on a bearing provided between the two casings in such manner as to be split into two halves at an intermediate portion or the other end thereof. With this construction, the oil pump body can be molded together with the casing, thereby making it possible to reduce the number of components used and man hours for assembling. In addition, since the bearings can be split into two halves, when compared with other portions of the balance shafts, the journal portion can be thinned, thereby making it possible not only to reduce the sliding friction but also to make the casing smaller in size and lighter in weight. More over, the degree of freedom of designing balance shafts can also be improved. With the balance shaft supporting structure for an engine the durability of a balancer, as well as the degree of freedom of designing the same are improved without making the engine larger in size and increasing the number of components used.
