Abstract

In a solid precursor evaporation system configured for use in a thin film deposition system, such as thermal chemical vapor deposition (TCVD), a method for preparing one or more trays of solid precursor is described. The solid precursor may be formed on a coating substrate, such as a tray, using one or more of dipping techniques, spin-on techniques, and sintering techniques.

Claims (5)

1. A method for preparing a solid precursor for use in a solid precursor evaporation system comprising:

forming said solid precursor in a solid tablet form from a solid metal-carbonyl powder form selected from Mo(CO) 6 , Co 2 (CO) 8 , Rh 4 (CO) 12 , Re 2 (CO) 10 , Cr(CO) 6 , Ru 3 ,(CO) 12 , or Os 3 (CO) 12 , wherein said forming said solid precursor in said solid tablet form comprises performing a sintering process in at least one of a vacuum atmosphere or in an inert atmosphere; and

disposing said solid precursor in a tray configured to be positioned within said solid precursor evaporation system.

2. The method of claim 1 , wherein said forming said solid precursor in said solid tablet form from said solid powder form includes forming said solid precursor on a coating substrate, and said coating substrate is disposed in said tray.

3. The method of claim 2 , wherein said forming said solid precursor on said coating substrate includes forming said solid precursor on said tray.
