Publication number: 20240142878Abstract: Example implementations described herein include a laser source and associated methods of operation that can balance or reduce uneven beam profile problem and even improve plasma heating efficiency to enhance conversion efficiency and intensity for extreme ultraviolet radiation generation. The laser source described herein generates an auxiliary laser beam to augment a pre-pulse laser beam and/or a main-pulse laser beam, such that uneven beam profiles may be corrected and/or compensated. This may improve an intensity of the laser source and also improve an energy distribution from the laser source to a droplet of a target material, effective to increase an overall operating efficiency of the laser source.Type: ApplicationFiled: January 10, 2024Publication date: May 2, 2024Inventors: Tai-Yu CHEN, Shang-Chieh CHIEN, Sheng-Kang YU, Li-Jui CHEN, Heng-Hsin LIU

Publication number: 20240103378Abstract: The present disclosure provides an extreme ultraviolet (EUV) lithography system including a radiation source and an EUV control system integrated with the radiation source. The EUV control system includes a 3-dimensional diagnostic module (3DDM) designed to collect a laser beam profile of a laser beam from the radiation source in a 3-dimensional (3D) mode, an analysis module designed to analyze the laser beam profile, a database designed to store the laser beam profile, and an EUV control module designed to adjust the radiation source. The analysis module is coupled with the database and the EUV control module. The database is coupled with the 3DDM and the analysis module. The EUV control module is coupled with the analysis module and the radiation source.Type: ApplicationFiled: November 30, 2023Publication date: March 28, 2024Inventors: Tai-Yu CHEN, Tzu-Jung PAN, Kuan-Hung CHEN, Sheng-Kang YU, Shang-Chieh CHIEN, Li-Jui CHEN, Heng-Hsin LIU

Publication number: 20120101203Abstract: The invention provides a compound and method of producing the same. The method of the invention includes the following steps. First of all, Polycaprolactone (PCL), dimethylol propionic acid (DMPA), 4,4?-methylenebis (cyclohexyl isocyanate) (H12MDI), and dibutyltin dilaurate (DBT) are mixed in a solvent in the first place and a solution is formed. This solution is then mixed with triethylamine (TEA) and triethylene tetramine (TETA). After that, amino-terminated anionic waterborne polyurethane (WPU) is produced. A sol-gel process is proceeded with a mixture of amino-terminated anionic waterborne polyurethane, tetraethylorthosilicate (TEOS) without any extra catalyst, and a compound, waterborne polyurethane-silica nanocomposite materials, is eventually produced.Type: ApplicationFiled: January 1, 2012Publication date: April 26, 2012Inventors: Chi-Fa Hsieh, Jui-Ming Yeh, Tai-Kang Liu

Patent number: 8071032Abstract: The invention discloses a method and a system for manufacturing organopolysiloxane. The system comprises N raw material tanks, N gauging tanks, a first reactor, a second reactor and at least one product tanks which are arranged in order from high to low. The manufacturing method comprises the following steps of: firstly, N raw materials are added into the N raw material tanks respectively. Then, a plurality of processing parameters about the organopolysiloxane are inputted to control the N gauging tanks to measure the dosage of the N raw materials according to the processing parameters, which along with a cyclic siloxane monomer are inputted into the first reactor. The first reactor is controlled to carry on ring-opening and re-distribution polymerization equilibrium reaction to the N raw materials and the cyclic siloxane monomer, so as to generate an intermediate product, and transfer the intermediate product into the second reactor.Type: GrantFiled: June 7, 2009Date of Patent: December 6, 2011Assignee: Chung-Shan Institute of Science and Technology Armaments Bureau, Ministry of National DefenseInventors: Tai-Kang Liu, Chi-Fa Hsieh

Patent number: 7822583Abstract: A design method of batch falling strand devolatilizers is disclosed. The method includes following steps. Firstly, construct a database that contains data of batch falling strand devolatilizer vs. devolatilization of at least one kind of polymer. Then data in the database is substituted into a mass balance difference equation to get a backmixing parameter. When the backmixing parameter is zero or is approaching zero, a liquid diffusion stage efficiency equation having a film equation or a pool equation is integrated with the mass balance difference equation to get a devolatilization process efficiency equation. By optimizing of a theoretical value of the backmixing parameter, a theoretical value of the process efficiency from calculation of the devolatilization process efficiency equation approaches the value of the process efficiency.Type: GrantFiled: April 16, 2007Date of Patent: October 26, 2010Assignee: Chung Shan Institute of Science and Technology, Armaments Bureau, M.N.D.Inventors: Tai-Kang Liu, Chi-Fa Hsieh
