US Patent:

56980370, Dec 16, 1997

Filed:

Jul 2, 1993

Appl. No.:

8/086970

Inventors:

Craig M. Stauffer - Santa Clara CA

International Classification:

C23C 1600

US Classification:

118726

Abstract:

An integrated module with a heated reservoir to vaporize liquid for semiconductor processes with liquid sources is presented. Shut-off valves and a proportioning pressure valve for controlling the flow of the vapor from the reservoir are mounted on the module for simple conduction heating of the valves. A capacitance manometer also mounted to the module also has its own heating elements. Condensation of the vapor is avoided and consistence performance and reliability is obtained.

Appl. No.:

8/566666

International Classification:

US Classification:

Abstract:

Top surface imaging by silylation of organic photoresists for use in lithographic techniques for the manufacture of microelectronic devices is improved by the use of certain mixtures of organosilane silylating agents. The mixture includes a monofunctional silane in combination with a di- or polyfunctional silane, selected such that the boiling points are the same or very close to each other to facilitate a vapor-phase reaction. Silylation with this mixture provides effective penetration of the silane into the resist without causing so much lowering of the glass transition temperature of the resist that the resist flows under the processing steps and distorts the pattern.
