Publication number: 20200393026Abstract: The linear driving mechanism includes a main body, a linear moving component, a guiding component and a driving component. The main body includes a seat and a moving shaft. The driving component is connected to a rotating shaft of the seat. The moving shaft passes through a driving slot formed on the linear moving component. The guiding component is for guiding a linear movement of the linear moving component. A stroke of the linear moving component of the linear driving mechanism can be changed by approaching or distancing the linear moving component and the seat of the main body to increase or decrease the displacement of the moving shaft located inside the driving slot. Therefore, the linear driving mechanism has not only simple structure but also flexibility in use.Type: ApplicationFiled: June 11, 2020Publication date: December 17, 2020Inventors: Wei-Yu Chang, Chih-Rong Chen

Publication number: 20180011967Abstract: The present invention discloses a method of real-time quantification of a target nucleic acid in a sample by constructing a reference table of copy number vs. designated parameter from reference samples which sharing the same nucleic acid sequences with the target nucleic acid. After that, obtain the designated parameter of the target sample and get the copy number by looking up and interpolating to the reference table. The object of the present invention is in particular provide methods for the quantification of the target nucleic acid which the target nucleic acid is quantified independently without comparing it to the standard controls by using a calibration curve. This invention will not only provide a new quantifying method, but will also propose a new standard operational method that eliminates the variations accompanying amplification efficiency, polymerase activity, primer concentrations, and instrument variations.Type: ApplicationFiled: July 5, 2016Publication date: January 11, 2018Inventors: Jr Winston WONG, Stephen, Chang-Chi KAO, Ying-Ta Lai, Yih-Jyh Shann, Ming-Fa Chen, Chih-Rong Chen

Publication number: 20010050563Abstract: A method for measuring contact resistance of a test key pattern is provided. The test key pattern includes several connecting conductive structures and several contacts. The method includes applying a first bias VD1 between a first measuring leg and a second measuring leg so as to produce a first current ID1, in which the connecting conductive structures and the contacts are chained together in series between the two legs. The first current is measured. The number of the connecting conductive structures and the number of the contacts between the first and second measuring legs are counted, respectively denoted as B and A, so as to set a first equation of VD1/ID1=A·Rc+B·Rs, where Rs and Rc respectively represent a single resistance of the connecting conductive structures and a single resistance of the contacts. A third measuring leg in between the first and second measuring legs.Type: ApplicationFiled: April 28, 1999Publication date: December 13, 2001Inventor: CHIH-RONG CHEN

Patent number: 6214709Abstract: A method of fabricating salicide. A metal layer is formed on a substrate with a polysilicon gate and a source/drain region. A material layer is then formed on the metal layer, wherein the material is selected to produce compressive stress as compressive stress is produced on the substrate and to produce tensile stress as tensile stress is produced in the substrate. The material layer needs to be chosen with the same stress produced by the metal layer. A thermal process is then performed on the substrate to form a silicide on the polysilicon gate and the source/drain region. The material layer and the unreacted metal layer are removed and therefore the salicide process is accomplished.Type: GrantFiled: August 4, 1998Date of Patent: April 10, 2001Assignee: United Microelectronics Corp.Inventor: Chih-Rong Chen

Patent number: 6171732Abstract: A method of forming a dual alignment photomask. The method includes the steps of depositing a light-blocking layer over a glass plate, and then patterning the light-blocking layer. Next, a switchable mask layer is deposited over the light-blocking layer and the glass plate, after which the switchable mask layer is patterned. Finally, a protective layer is formed over the switchable mask layer, the light-blocking layer and the glass plate. The switchable mask layer can be changed from a light-passing state to a light-blocking state by simply changing the surrounding temperature. Therefore, through proper setting the temperature, the same photomask can be used to form trenches and vias of dual damascene structures. Thus, some mask-making cost can be saved and errors due to mask misalignment can be avoided.Type: GrantFiled: May 4, 1999Date of Patent: January 9, 2001Assignee: United Microelectronics Corp.Inventors: Chih-Rong Chen, Wen-Yuan Huang
