Abstract:
1. A method for coating a pattern of a thin film of a non-polymerizable compound on a substrate comprising the steps of: a. providing a mixture of said non-polymerizable compound and a liquid carrier, b. pumping said mixture to the interior of a heated evaporation box, c. exposing said mixture to a temperature within said heated evaporation box sufficient to convert substantially all of said non-polymerizable compound and liquid carrier to a gaseous form, d. removing said non-polymerizable compound and liquid carrier in said gaseous form through an exit slit in said evaporation box, e. condensing said non-polymerizable compound on a first substrate maintained in a vacuum and in motion relative to said exit slit in said evaporation box, f. directing an energy source to said first substrate, thereby removing a portion of said non-polymerizable compound from said first substrate, and g. depositing said removed non-polymerizable compound onto a second substrate in a predetermined pattern.
