来自主题: WaterWorld版 - Temptation(诱惑)
Diana Krall 的最新版 Temptation,
跟以前的诠释不太一样,值得玩味。
另外小小的感叹一下,河马估计就是跌在
“I can't resist” 那句上了。。。
美好人生要懂得拒绝诱惑。。。有时候
还是蛮唏嘘的。。。

Temptation
Rusted brandy in a diamond glass
Everything is made from dreams
Time is made from honey slow and sweet
Only the fools know what it means
Temptation, temptation, temptation, I can't resist

铜和阳极铝根本不在考虑之列。
Despite the great numbers of metals and alloys known to man, remarkably few
warrant even preliminary consideration for uses as implant materials. The
relatively corrosive environment combined with the poor tolerance of the
body to even minute concentrations of most metallic corrosion products
eliminates from discussion most metallic materials. Of the possible metallic
candidates, tantalum and the noble metals do not have suitable mechanical

上次在某个帖子里提到一个观点:

Deadly Diabetes Deception
Introduction
If you are an American diabetic, your physician will never tell you that
most cases of diabetes are curable. In fact, if you even mention the "cure"
word around him, he will likely become upset and irrational. His medical
school training only allows him to respond to the word "treatment". For him,
the "cure" word does not exist. Diabetes, in its modern epidemic form, is a
curable disease and has been for at least 40 years. In 2001, the most

1.400nm好象是比较厚,你的substrate材料如果是半导体的话
电子的backscattering会很散(你应该不会是在用100KeV的
e-beam吧?),所以proximity effects会很严重造成在你没想
曝光的(邻近)位置也overdosed.这样如果是positive resist
你的pattern线条会过细(因为你没考虑PROXIMITY EFFECT修正)
目前的positive resist中PMMA和ZEP所能做的极限线宽都在十
多个nm以上,小于这个极限就很难做了.而你的膜厚是预期线宽
的10倍以上,resist很容易塌下来,如果你的SEM分辨率不够好的
话很容易分辨不出这种坍塌.另外如果你是想做30nm的槽的话,
结果正好反过来--槽的线宽过大,所以你就会觉得没达到30nm.
2.如果要在100nm的金属膜上做pattern,想必你的计划不外乎先做
resist pattern 再蒸镀金属或者直接在金属层上做resist
pattern再etching.前者的问题是400nm的槽里如果要淀积30nm宽
