Abstract :
The improvement of global planarity after the Low-k film formation is indispensable for raise of the yield and reduction of the steps for planarization in dual damascene multilayer interconnection process. We confirmed that scan coating has more excellent uniformity and planarization ability than conventional spin coating.
