Otherwise, it can't successfully transfer the original pattern to the wafer surface causing device and circuit failure and the photo resist must be very sensitive to the exposure light to achieve reasonable throughput and the standard thickness should be 1.2μm. 24 wafers are used in this study, the wafers are separated into 2 sets, and each set which consists of 12 wafers. The first set is coated, exposed and development and the second set is also exposed and developed after being coated. after the wafer went through the standard cleaning procedure, the wafers were then coated using standard recipes which the spin speed ranging from 6500 to 7600 rpm in 100 rpm incremental Subsequently, the photoresist thickness of each wafer is measured using elipsometer. The study revealed that the minima for the dose-to-clear are at 7200 rpm where the thickness is 1.21 μm. Though, the result is slightly thicker than the expected 1.2 μm. This may be due to some unavoidable experimental errors and may due to the changing k' of the coater because coater is a bit old. 2013-07-13T08:54:35Z 2013-07-13T08:54:35Z 2012 Article Journal of Applied Sciences Research, vol. 8(8), 2012, pages 4268-4272 1816-157X http://www.aensiweb.com/jasr/jasr/2012/4268-4272.pdf http://hdl.handle.net/123456789/26639 en INSInet Publications
