Title: Contact process with active region arrangement conversion and active mask doubly utilized
Inventor: LEE TZUNG-HAN
IPC: H01L21/768
Filed: 2000-06-05
Granted: 2001-11-01
Abstract: A contact process of DRAM with active region arrangement conversion and active mask doubly utilized is hereby disclosed. After completing the definition of the spacer and poly 1 and depositing the interpoly dielectric, an active region is etched after being defined by negative photoresist and mask and is larger than the conventional contact. Then fill poly 2 into the active region. Since this active region is wider than the conventional contact, its aspect ratio is smaller. So the filling of poly 2 is easier than that of the conventional process. Then apply photoresist and mask to define and etch the shape of poly 2. In the etching process, the poly 2 layer remains along the edge of the device, and the residue by the side of the spacer of poly 1 becomes a passivation layer same as a spacer. With the protection of double spacers, the margin of the following contact etching process is increased. It is also possible to perform the ion implantation process of source/drain at the etched open position of the poly 2 layer.

Filed: 1998-07-04
Granted: 2001-11-21
Abstract: In order to prevent accumulation of rounding errors caused by the integer-based bilinear interpolation used in the motion compensation process of image coding and decoding methods, two types of P frames are used for unidirectional motion compensation prediction, namely: P+ frames, which round the results of bilinear interpolation with real number operations to the nearest integer and rounds half integer values (0.5 added to an integer) away from zero, and P- frames, which differs from P+ frames that the above mentioned half integer values are rounded towards zero. Utilizing both of these P+ and P- frames enables cancelling of rounding errors and prevents the accumulation of rounding errors.

Title: Routing path finding method for automated routing/designing process and computer-readable storage medium having stored thereon routing path finding program
Inventor: HAMAWAKI KOJI
IPC: G06F9/45
Filed: 2000-08-03
Granted: 2001-09-21
Abstract: In an automatic routing/designing process of an LSI using a maze algorithm, multiple sub-regions, formed by getting a grid column partitioned by a component placed in a routing region, are extracted. And grid point availability, representing the number of grid points available for routing, is obtained for each of these sub-regions. Also, if there is any open net, then the component is vertically moved upward by one grid unit, for example, to make the net routable. If the grid point availability of a sub-region, used for routing another net, has become negative as a result of the movement of the component, then the net is rerouted to pass other sub-regions. Accordingly, even if a height constraint, for example, has been imposed on the routing region, all of the nets can be routed successfully with the constraint satisfied without increasing the number of grid points in the column direction. As a result, the number of open nets can be minimized and all of the nets are much more likely to be routed successfully.
