Abstract:
A method for manufacturing a spin-on thin film provided on a semiconductor wafer, comprising the steps of:(a) selecting a solution comprising a precursor and a solvent; (b) for said solution, determining an acceptable first acceleration rate in the range of about 1.6Ã—105 to about 2.5Ã—108 rpm/sec, a first rotation speed, a first rotation duration, a deceleration rate, a second rotation speed slower than said first rotation speed, and a second rotation duration; (c) providing said solution on said wafer in a sealed deposition chamber; then (d) accelerating said wafer at said first acceleration rate to said first rotation speed for said first rotation duration in said sealed deposition chamber; and then (e) decelerating said wafer at said deceleration rate to said second rotation speed for said second rotation duration, and wherein said solution of precursor is liquid during at least a portion of said second rotation duration.
