欧盟肉仔鸡福利的问题分析

中国禽业导刊 2007年第19期24卷 11-11页

作者： jacky Turner Leah Garces wendy Smith 滕小华东北农业大学动物科学技术学院哈尔滨150030

肉仔鸡是饲养鸡的专门化类型，其肉供食用。每年欧盟大约饲养5.9×10^9只肉用仔鸡，大多数肉仔鸡集约饲养在无窗户、环境贫瘠、拥挤的鸡舍里。这些鸡在整个6-7周的时间里一直呆在这样的环境中。实际上，直到2005年依然没有明确的有关保... 详细信息

本文研究了N型MOSFET在高漏压低栅压条件下的热载流子注入效应。在3.3V N型MOSFET的漏端和栅极上分别加上5.5V和0.65V电压,发现在电应力条件下的漏端电流Id随着施加应力的时间增加而增大。导致这个现象的主要机制是漏端附近氧化层中产生了带正电荷的缺陷。另外还发现,在栅极施加反方向电压,漏端电流Id并不能发生恢复。但是125℃烘烤8小时后,漏端电流Id会发生恢复,表明空穴在加热时得到足够的能量而从缺陷陷阱中跃迁出来。此外,本文在通过研究工艺改进来提升HCI的性能中,发现在合适的氮化硅退火温度和轻掺杂漏区(Lightly Doped Drain,LDD)掺杂浓度能有效的降低NMOSFET空穴注入。
