Patent number: 7241538Abstract: Critically representative features (CRF's) for use in mask-making verification and/or resist development verification are defined and/or copied into the in-scribe area used by wafer CD features. The placement of mask-CRF's in the wafer CD bar region eliminates the problem of correctly and quickly locating mask-CRF's at different positions in the in-die areas of a manufactured mask. On-wafer counterparts of the mask-CRF's may be used for fine-tuning lithography and patterning processes.Type: GrantFiled: November 5, 2003Date of Patent: July 10, 2007Assignee: ProMOS TechnologiesInventors: Feng-Hong Zhang, Limin (Eric) Lou

Publication number: 20030234659Abstract: A new apparatus and method for simultaneously testing a plurality of circuit devices are achieved. The apparatus comprises, first, a tester having at least one output signal. A plurality of circuit devices is used. Each circuit device has at least one input signal. Finally, a plurality of auto-reset fuses is used. Each auto-reset fuse is coupled between the tester output signal and one of the input signals of the plurality of circuit devices. The auto-reset fuses automatically switch from low impedance during low current to high impedance during high current. The auto-reset fuses automatically switch from high impedance to low impedance after a waiting time.Type: ApplicationFiled: June 20, 2002Publication date: December 25, 2003Applicant: Promos TechnologiesInventor: Jan Zieleman

Patent number: 6633793Abstract: A new method to reduce variation in an output parameter by selection of an optimal process recipe in the manufacture of an integrated circuit device is achieved. The method may be used to reduce the array voltage threshold in a DRAM circuit by compensating the source/drain ion implantation by calculating a predicted array voltage threshold. The integrated circuit device wafer is measured to obtain a present set of process parameter values. A predicted value of an output parameter is calculated by evaluating a first equation at the present set of process parameter values. The first equation is derived from a plurality of previous sets of process parameter values and the corresponding plurality of sets of output parameter values. The difference between the predicted value of the output parameter and a target value of the output parameter is the output parameter delta. A process recipe offset is calculated by evaluating a second equation at the output parameter delta.Type: GrantFiled: August 13, 2001Date of Patent: October 14, 2003Assignee: ProMos TechnologiesInventors: Joseph Wu, Hsiao-Li Wang

Patent number: 6630397Abstract: In accordance with the objectives of the invention a new processing sequence is provided for the creation of a layer of ARC. A first layer of ARC is deposited over a supporting surface, a blanket etch is performed to the surface of the first layer of ARC, leaving any openings that have been created in the supporting surface essentially filled with ARC material. A second layer of ARC is next applied over the surface of the etched first layer of ARC, this second layer of ARC provides a layer of ARC that is of uniform thickness over the supporting surface. Steps of baking may be applied to each of the layers of ARC after these layers have been deposited or after the first layer of ARC has been etched.Type: GrantFiled: December 10, 2002Date of Patent: October 7, 2003Assignee: ProMos TechnologiesInventors: Jackie Ding, Sheng-Fen Chiu, Chi-Long Chung

Patent number: 6578177Abstract: A new method of forming gate conductor lines for a DRAM in the manufacture of an integrated circuit device has been achieved. A semiconductor substrate is provided. Active areas are defined. A gate conductor layer is deposited overlying the semiconductor substrate. The gate conductor layer is patterned to form gate conductor lines. The intersections of the gate conductor lines and the active areas form DRAM transistors. Adjacent gate conductor lines are spaced a first minimum distance in critical regions and are spaced a second minimum distance in non-critical regions. The critical regions are defined as the active areas between adjacent gate conductor lines where bit line contacts are planned. The non-critical regions are defined as areas located between the critical regions and the adjacent gate conductor lines. The second minimum distance is greater than the first minimum distance to thereby decrease the aspect ratio in the non-critical regions to less than the aspect ratio in the critical regions.Type: GrantFiled: August 13, 2001Date of Patent: June 10, 2003Assignee: ProMos TechnologiesInventors: Joseph Wu, Yu-Ping Chu
