20150056123 | POLYCRYSTALLINE SILICON INGOT, PREPARATION METHOD THEREOF, AND POLYCRYSTALLINE SILICON WAFER - Disclosed is a preparation method of a polycrystalline silicon ingot. The preparation method comprises: providing a silicon nucleation layer at the bottom of a crucible, and filling a silicon material above the silicon nucleation layer; heating the silicon material to melt same, adjusting the thermal field inside the crucible to make the melted silicon material to start crystallization on the basis of the silicon nucleation layer; and when the crystallization is finished, performing annealing and cooling to obtain a polycrystalline silicon ingot. By adopting the preparation method, a desirable initial nucleus can be obtained for a polycrystalline silicon ingot, so as to reduce dislocation multiplication during the growth of the polycrystalline silicon ingot. Further disclosed are a polycrystalline silicon ingot obtained through the preparation method and a polycrystalline silicon wafer made using the polycrystalline silicon ingot as a raw material. | 02-26-2015 |

20120307154 | HYBRID MODE REPEATER/RE-DRIVER FOR HIGH SPEED DIGITAL VIDEO SIGNALING - A system and a method are disclosed for a hybrid mode re-driver which, among other advantages, reduces power consumption while maintaining signal integrity. Equalization is performed on a signal to remove distortions such as inter-symbol interference. The signal is then analyzed and the quality of the signal is assessed. In some cases, retiming is then performed on the signal to remove additional signal distortions. In other cases, retiming is not performed and is transmitted to a driver while bypassing retiming components. When retiming components are bypassed, the retiming components are placed in a state of reduced power consumption to reduce system power consumption. | 12-06-2012 |
