A bank structure for a display panel is provided. The display panel comprises a substrate, and the bank structure is formed on the surface of the substrate. The bank structure comprises a periphery and a partition, wherein the periphery forms a receiving space with the substrate and the partition is disposed in the receiving space for separating the receiving space into two sub-spaces with fluid-communication. Therefore, the ink can be injected and uniformly distributed in the sub-spaces to overcome the disadvantages of poor injection precision and increasing the spray control of the ink.

An ink composition for producing a color filter is provided. The ink composition comprises a colorant, a binder and plural solvents. A color filter production method using the above-mentioned ink composition is also provided. The ink composition is adhered to the designated light transmitting regions on the surface of a transparent substrate. Then, the ink composition adhered to the designated light transmitting regions is solidified.

A method of correcting optical proximity effect of contact holes. Corresponding relations between mask critical dimensions (mCDs) and photoresist critical dimensions (pCDs) for each pitch (d) are formed. Correction of each mCD for each combination of pCDs and pitches is determined based on the corresponding relations. The correction is used first to correct each contact hole of a processing mask pattern. The first corrected contact hole of the processing mask pattern is corrected again to a square having the same area as the first corrected contact hole and the same center as the uncorrected contact hole.
摘要:
A method for evaluating reticle registration between two reticle patterns. A wafer is defined and etched to form a first exposure pattern, by photolithography with a first reticle having a first reticle pattern thereon. A photoresist layer is formed over the wafer and defined as a second exposure pattern, by photolithography with a second reticle having a second reticle pattern thereon. A deviation value between the first and second exposure patterns is measured by a CD-SEM. The deviation value is calibrated according to the scaling degree and the overlay offset to obtain a registration data. The reticle registration between the two reticle patterns is evaluated based on the registration data.

摘要:
A method of improving lithography resolution on a semiconductor, including the steps of providing a substrate on which a protecting layer, a first etching layer and a photoresist layer are sequentially formed; patterning the photoresist layer to form an opening so as to partially reveal the first etching layer; implanting a first ion into the revealed first etching layer to form a first doped area; and implanting a second ion into the revealed first etching layer to form a second doped area, wherein the first doped area is independent from the second doped area is provided.

An overlay mark formed on a photomask, comprising a first rectangular region, a second rectangular region, a third rectangular region, and a fourth rectangular region, each rectangular region having the same pattern configuration, a longer side of the first rectangular region and a longer side of the third rectangular region being parallel to each other, and the first and third rectangular regions have the same first pattern configuration having a first pattern element, a longer side of the second rectangular region and a longer side of the fourth rectangular region being parallel to each other, and the second and fourth rectangular regions have the same second pattern configuration having a second pattern element, the longer side of the first rectangular region being perpendicular to the longer side of the second rectangular region; wherein, the first pattern element is different from the second pattern element for allowing the second pattern configuration be chosen to align when the first pattern configuration on the substrate was damaged during process.
摘要:
A method for enhancing adhesion between a reworked photoresist and an underlying oxynitride film. A photoresist pattern layer is formed on an oxynitride layer overlying a substrate. The photoresist pattern layer is removed by acidic solution or oxygen-containing plasma. A surface treatment is performed on the oxynitride layer using a development solution to repair the damaged oxynitride layer due to removing the overlying photoresist pattern layer. A reworked photoresist pattern layer is formed on the oxynitride layer.

摘要:
An optical proximity correction (OPC) method for correcting a photomask layout. The photomask layout has at least a photomask pattern. The steps of the OPC method include collecting an assist feature bias of a predetermined assist feature, performing a rule-based OPC by taking account of the assist feature bias to compute a target bias of the photomask layout, outputting a corrected photomask layout according to the target bias, and adding the predetermined assist feature to the corrected photomask layout.
