Filed:

Dec 12, 1990

Appl. No.:

7/624320

Inventors:

Michael R. Bonsaver - Phoenix AZ
Rand A. Conner - Chandler AZ
David P. Lambert - Costa Mesa CA

Assignee:

Advanced Semiconductor Materials America, Inc. - Phoenix AZ

International Classification:

C23C 1648

US Classification:

427569

Abstract:

A transmission line is constructed from ceramic and nickel materials to provide a characteristic impedance that matches the characteristic impedance of a boat assembly in a chemical vapor deposition system. The transmission line is interposed between a set of feedthroughs through the wall of a reactant tube and a set of contacts on the boat assembly. The transmission line improves the efficiency of the power transfer to the boat assembly from an RF power source external to the reactant tube. The transmission line is particularly advantageous at high frequencies such as, for example, 13. 56 MHz. This improves the repeatability of the deposition of film on wafers in the boat assembly.
