20100117140 | NON-VOLATILE MEMORY DEVICE FOR 2-BIT OPERATION AND METHOD OF FABRICATING THE SAME - A non-volatile memory device for 2-bit operation and a method of fabricating the same are provided. The non-volatile memory device includes an active region and a gate extending in a word line direction on a semiconductor substrate, and crossing each other repeatedly; a charge storage layer disposed below the gate, and confined at a portion where the gate and the active region cross; a charge blocking layer formed on the charge storage layer; a tunnel dielectric layer formed below the charge storage layer; first and second source/drain regions formed in the active region exposed by the gate; and first and second bit lines crossing the word line direction. The active region may be formed in a first zigzag pattern and/or the gate may be formed in a second zigzag pattern in symmetry with the first zigzag pattern. | 05-13-2010 |

20110202892 | RETARGET PROCESS MODELING METHOD, METHOD OF FABRICATING MASK USING THE RETARGET PROCESS MODELING METHOD, COMPUTER READABLE STORAGE MEDIUM, AND IMAGING SYSTEM - In a retarget process modeling method, an effect according to density of patterns, and shapes or distances with respect to neighboring patterns may be sufficiently reflected while a relatively small amount of time and few costs are consumed. The retarget process modeling method involves obtaining prediction data, by a modelling calculating unit, on a test layout using a first process model, obtaining bias data based on measurement data of the test layout and the prediction data, using the bias data to check and detect corresponding features of a representative pattern affected by a photoresist (PR) flow rate, generating kernels including a PR flow kernel in consideration of a sub resolution assist feature (SRAF) pattern of the representative pattern to determine an uncalibrated model including the kernels and obtaining a second process model by fitting the uncalibrated model to the measurement data to obtain a second process model. | 08-18-2011 |
