摘要

利用金属-绝缘体-半导体(MIS)电容器研究了不同孔隙度(k=2.0, 2.5, 2.8和3.0)的四种有机硅酸盐-玻璃(OSG)薄膜的时间相关介电击穿(TDDB)。在没有任何阻挡的情况下,介质在Cu离子漂移条件下表现出较低的tddb寿命,osg -2.8薄膜表现出更好的性能。另外,TaN/Ta屏障的损伤对TDDB的性能没有显著影响,osg -2.0薄膜的TDDB寿命也很好。

Time dependent dielectric breakdown study of organo silicate glass materials over a wide range of k-values
The time dependent dielectric breakdown (TDDB) of four organo-silicate-glass (OSG) films with varying porosity (k=2.0, 2.5, 2.8 & 3.0) was investigated using metal-insulator-semiconductor (MIS) capacitors. Without any barrier, the dielectrics show lower TDDB-lifetimes under Cu ion drift conditions, where the OSG-2.8-film exhibits a better performance. Other results are that the damage caused by TaN/Ta barriers doesn't significantly change the TDDB performance and that the OSG-2.0-film showed excellent TDDB lifetimes.
