Hi, Amit, Long-Sun:
    Your words makes me feel confident for what I read, so I tried the
experiment today, it really works!
    "Fundamentals of Microfabrication" also delievers useful issues!
    Besides, it tells me that "Slow etching doesn't mean smooth result"!
     THANKS!

    Helps me A LOT!!
Sincerely,
