  • Patent number: 10475649
    Abstract: A patterning method includes the following steps. A hard mask layer is formed on a substrate. Mandrels are formed on the hard mask layer. Mask patterns are formed on the mandrels. Each of the mask patterns is formed on one of the mandrels. Spacers are formed on the hard mask layer. Each of the spacers is formed on a sidewall of one of the mandrels and on a sidewall of one of the mask patterns. A cover layer covering the hard mask layer, the spacers and the mask patterns is formed. A planarization process is performed to remove the cover layer on the mask patterns and the spacer and remove the mask patterns. A part of the cover layer remains between the spacers after the planarization process. The mandrels and the cover layer are removed after the planarization process.

  • Patent number: 10032631
    Abstract: A method of fabricating a mask pattern includes providing numerous masks on a substrate. A wider trench and a narrower trench are respectively defined between the mask. Subsequently, a mask material is formed to fill in the wider trench and the narrower trench. The top surface of the mask material overlapping the wider trench is lower than the top surface of the mask material overlapping the narrower trench. A photoresist layer is formed on the mask material overlapping the wider trench. Later, the mask material overlapping the narrower trench is etched while the mask material overlapping the wider trench is protected by the photoresist layer.

  • Publication number: 20170010605
    Abstract: A method of controlling a delivery to a working station comprises processing first carrier of wafers at a working station for a processing step, checking location of a second carrier at a predetermined checking time to obtain a checking result. The predetermined checking time is a predetermined period of time ahead of an end of the processing step. The method further comprises removing the first carrier from the working station after the processing step is completed, delivering a second carrier of wafers to the working station and processing the second carrier of wafers at the working station.

  • Patent number: 9466410
    Abstract: A slide-type variable resistor comprises a shell, two side guiding tracks, two end locking parts, a variable resistor circuit base, and a manipulating device. The two side guiding tracks are symmetrically assembled in the allocation space. The two end locking parts are symmetrically pressing against the two side guiding tracks respectively to have the two side guiding tracks positioned in the allocation space. The variable resistor circuit base is assembled to the shell and utilized for pressing against the two end locking parts to have the two end locking parts and the two side guiding tracks fixed in the allocation space. The manipulating device comprises a brush base, at least a brush, and a bar. The brush base has two symmetrically positioned sliding tracks slidably positioned in the two side guiding tracks. The brush is connected to the brush base and has elastic recovery to press against the variable resistor circuit base.
