Abstract:
A method of forming a dielectric on a substrate, comprising the steps of:providing a substrate having a first surface and an axis, wherein said axis is at the center of and perpendicular to said first surface of said substrate;providing means for rotating said substrate about said axis;placing said substrate on said means for rotating said substrate about said axis;rotating said substrate about said axis at a first angular velocity while depositing a first volume of cleaning solution on said first surface of said substrate;rotating said substrate about said axis at said first angular velocity for a first time after said first volume of cleaning solvent has been deposited on said first surface of said substrate;rotating said substrate about said axis at said first angular velocity while depositing a second volume of uncured dielectric on said first surface of said substrate, wherein said second volume is less than said first volume;rotating said substrate about said axis at said first angular velocity for a second time after said second volume of uncured dielectric has been deposited on said first surface of said substrate;rotating said substrate about said axis at a second angular velocity for a third time after said second volume of uncured dielectric has been deposited on said first surface of said substrate and said substrate has been rotated about said axis at said first angular velocity for said second time; andremoving said substrate from said means for rotating said substrate about said axis.
