Oct 9, 2001

Appl. No.:

09/974507

Inventors:

Yong Liu - Fremont CA
Hua-Yu Liu - Palo Alto CA

Assignee:

Numerical Technologies, Inc. - Mountain View CA

International Classification:

G03F 900

US Classification:

430 5, 716 19

Abstract:

An accurate, cost-effective system and method for correcting 3D effects on an alternating phase-shifting mask (PSM) is provided. To facilitate this correction, a library can be built to include a first group of 180 degree phase-shifting regions, wherein these regions have a common first size. Based on this first size, 3D simulation is performed. A transmission and a phase are altered in a 2D simulation based on this first size until a shape dependent transmission and a shape dependent phase allow the 2D simulation to substantially match the 3D simulation. Finally, a modified first size is chosen using the shape dependent transmission and the shape dependent phase such that a 2D simulation based on the modified first size substantially matches the 3D simulation based on the first size. The library associates the first size with the modified first size, the shape dependent transmission, and the shape dependent phase.

US Classification:

370238, 370251, 370254, 709241

Abstract:

A data routing method and system, the data routing method including: locating a destination node using a destination locating packet; establishing a preliminary route including anchor nodes based on a route where the destination locating packet is transmitted to the destination node; determining a link cost between neighbor nodes of each of the anchor nodes, and also between the anchor nodes and the neighbor nodes of each of the anchor nodes; generating minimum cost information with respect to a route consuming a minimum cost from the destination node to a source node using the link cost; and forming a data route from the destination node to the source node using the minimum cost information.

US Classification:

324754, 324758

Abstract:

An apparatus and method for testing large area substrates is described. The large area substrates include patterns of displays and contact points electrically coupled to the displays on the large area substrate. The apparatus includes a prober assembly that is movable relative to the large area substrate and/or the contact points, and may be configured to test various patterns of displays and contact points on various large area substrates. The prober assembly is also configured to test fractional sections of the large area substrate positioned on a testing table, and the prober assembly may be configured for different display and contact point patterns without removing the prober assembly from the testing table.

International Classification:

G06F 17/50

US Classification:

716 19, 716 21

Abstract:

A method for determining a mask pattern to be used on a photo-mask in a photolithographic process is described. During the method, a target pattern that includes at least one continuous feature is provided. Then a mask pattern that includes a plurality of distinct types of regions corresponding to the distinct types of regions of the photo-mask is determined. Note that the mask pattern includes at least two separate features corresponding to at least the one continuous feature. Furthermore, at least the two separate features are separated by a spacing having a length and the spacing overlaps at least a portion of at least the one continuous feature.

Abstract:

Embodiments of a method for determining a mask pattern to be used on a photo-mask in a lithography process are described. This method may be performed by a computer system. During operation, this computer system receives at least a portion of a first mask pattern including first regions that violate pre-determined rules associated with the photo-mask. Next, the computer system determines a second mask pattern based on at least the portion of the first mask pattern, where the second mask pattern includes second regions that are estimated to comply with the pre-determined rules. Note that the second regions correspond to the first regions, and the second mask pattern is determined using a different technique than that used to determine the first mask pattern.

Abstract:

A method and system for allocating subcarrier frequency resources for a relay enhanced cellular communication system is provided. The relay enhanced cellular communication system includes a base station, one or more mobile stations and one or more relay stations. Subcarrier allocation involves assigning a set of subcarriers by allocating subcarriers to one or more access communication links between mobile stations and their serving stations, to meet minimum data rate requirements of the access links, and allocating subcarriers to one or more relay communication links between the base station and relay stations to accommodate the data rates achieved on the corresponding access links. The serving stations may include one or more relay stations and the base station. Link balancing, multi-user diversity and minimum data rate constraint are jointly considered to achieve an optimal solution.
