China’s 65nm large-tilt-angle ion implanter | China's Great Science and Technology
"China's 65nm large-tilt-angle ion implanter
November 3, 2011
Beijing Zhongkexin Electronics Equipment Co. Ltd. (ZKX) independently developed its 65nm resolution large-tilt-angle ion implanter for 300mm wafers.
On October 26 1010, the 300mm/65nm large tilt angle ion implanter officially enter SMIC (Beijing) to be tested in the first-class production line in China’s semiconductor industry. By now, 300mm/65nm large title angle ion implanter has successfully completed the basic technical tests, including beam stability, element analysis ability, metal contamination, particle contamination, ion implantation uniformity and dose stability; the interim test results has also won the full recognition from SMIC. Technical staff in SMIC said that based on the earlier test results, they fully believe that the home-made equipment will successfully pass the final tests.
300mm/65nm large tilt angle ion implanter developed independently by ZKX is the most advanced equipment in China’s IC manufacturing equipment industry.
By strong support of Ministry of Science and Technology of the People’s Republic of China, the People’s Government of Beijing Municipality and China Electronics Technology Group Corporation, Beijing Zhongkexin Electronics Equipment Co. Ltd. (ZKX) is built as a high-tech enterprise and a holding company owned by 48th Research Institute of CETC. It is located in Opto-mechatronics Industrial Base, Tongzhou Park, Zhongguancun Science Park of Beijing.
The company covers 117 acres of land and owns more than 200 technical staffs, including 12 research professors, 60 senior engineers. The fields are covered by microelectronics, physics, optical, mechanical, electrical and others. It is mainly specialized in R&D and manufacture of IC key equipment and test products such as ion implanter and rapid thermal process system, R&D and production of photovoltaic products such as silicon solar cells and PV modules. It also provides technical service of various ion implantation equipment such as maintenance, repair, renovation and providing the related spare parts.
The 8-inch and 12-inch ion implanter and other semiconductor equipment have been sold in batches. Solar cell production line built by our own technologies and equipment has achieved large scale production and the products have been sold in the domestic market and overseas market."

Rotor for 1,000MW ultra-supercritical Steam Turbine | China's Great Science and Technology
"Rotor for 1,000MW Ultra-supercritical Steam Turbine
November 9, 2011
China has already manufactured a 12% Chromium high-quality forged rotor for an 1,000MW USC (ultra-supercritical) steam turbine under high pressure.
China’s strategy to meet its greenhouse gas commitment is to continue full steam ahead by converting its coal-fired power plant fleet from a conventional one to an ultra-supercritical one — a move that will decrease its energy intensity from coal-generated power by more than 20 percent.
A coal-fired power plant operates by boiling water to create a high-pressure steam that drives a turbine which produces electricity by moving an electrical wire through a magnetic field.
A conventional (or subcritical) plant typically operates at temperatures up to 1,050 degrees Fahrenheit and has an efficiency of between 33 and 39 percent. Operating a plant at higher temperatures and pressures can increase its efficiency, potentially lowering emissions of carbon dioxide (CO2) in the process.
A so-called supercritical plant operates at sufficiently high pressures and temperatures (between 1,000 and 1,075 degrees Fahrenheit) such that the water and steam become indistinguishable (the critical point of a liquid), allowing efficiency rates to reach 42 percent. An ultra-supercritical plant operates at temperatures of 1,075 degrees Fahrenheit and above and can achieve efficiencies of more than 42 percent.
China has jumped into the ultra-supercritical game with both feet. It is busy building supercritical and ultra-supercritical power plants at an astonishing rate — a whole lot faster, by the way, than we are here in the United States. And China’s ultra-supercritical power plant that went online in Yuhuan in 2006 reportedly holds the record as “the world’s cleanest, most efficient and most advanced ultra-supercritical units” with an efficiency of 46 percent.
Until now, the key high temperature equipment for supercritical and ultra-supercritical power units were mainly imported from foreign countries. China currently requires our national enterprises to domestically manufacture the key high temperature equipment. For making seamless tubes and large pipes, Chinese enterprises will be equipped with more 35MN, 60MN and one 350MN extrusion machines in the near future.
Large-scale castings for 1,000MW USC steam turbine already can be made in China. Large-scale forging have been also trial-produced. High-purity low alloy steel forging for low pressure rotor and 12% Cr high-quality forged rotor for 1,000MW USC steam turbine high pressure rotor are made in China."

Shenguang-2 (Shenguang-II) super laser | China's Great Science and Technology

Shenguang-II super laser
The ultimate objective of inertial confinement fusion (ICF) research is to achieve the realization of controllable nuclear fusion, a kind of subatomic reactions, in which the union of lighter atomic nuclei forms heavier ones in company with the release of an enormous amount of energy; in hope of solving the increasingly urgent issue of energy shortage in human society. Acting as an important experimental platform for the short-term and mid-term ICF studies in China, the Shenguang (Divine Light)-Ⅱ laser facility (SG-Ⅱ is the largest facility ever developed in this country and listed among the few high-performance and huge-power solid-state laser drivers in the world today.
In an area as large as a football field, the newly developed “Shenguang (magic rays) II” super laser, which consists of over a hundred optical apparatuses, is able to emit gigantic energy equal to that of a global electricity network in a spark of one billionth of a second; creating a physical phenomenon which is likely to be found only at the centre of a nuclear explosion, the rim of a black hole, or inside a star.
Shenguang-II super laser
Situated at the Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences (CAS), the super laser, by sending out tremendous energy in a very short time, could create extreme pressure and high temperature to trigger a fusion reaction.
By providing extreme physical conditions, the laser is to be used in scientific experiments and is of great significance to basic research, hi-tech applications, and the development of new technology for national defence.
“Shenguang” has a promising prospect, an expert says, because nuclear fusion holds out the hope of clean energy in future years. By the middle of this century, scientists (as expected) would be able to use laser-produced fusion to turn rich deuterium and tritium in seawater into great and endless energy. Completion of “Shenguang II” marks a step forward made by China towards obtaining energy from seawater.
With the successful development of “Shenguang II”, China has positioned itself in the world forefront for laser studies. For the moment, such huge and precise optical equipment can only be made in a few countries such as the USA and Japan, and the general technological performance of “Shenguang II” has entered the rank of the world Top 5.
In the research, development, test and physical experimental operation of the larger Shenguang-II devices, with the total output capacity of eight-route base-frequency laser (wavelength at 1,053nm) reaching 6kj/100ps. The remarkable progress made in the first laser fusion experiment conducted on Shenguang-II indicates that China has reached a new level in high-power laser physics and technology and in the theoretical research and experimental technology of laser-induced fusion."

"Implosion of Cone-in-shell Target on Shenguang Laser Facilities
Zhou, Weimin; Gu, Yuqiu; Shan, Lianqiang
American Physical Society, 52nd Annual Meeting of the APS Division of Plasma Physics, November 8-12, 2010, abstract #UO5.002
Experiments of indirectly driven implosion of cone-in-shell target for fast ignition have been carried out on Shenguang II and Sheguang III prototype laser facilities. Empty CD shells are imploded using 8 beams on both laser facilities. The neutron yield was measured by the scintillator detectors. 106˜107 neutrons were obtained in the experiments. On Shenguang II, the 9th beam was used to generate a Ti backlighter. The backlit image was measured via a X-ray framing camera with a time-gated resolution of 60 ps. On Shenguang III prototype, only self-emission of X-ray from the imploded shell was measured."
