Patent ID: 7216534

Claim:
A substrate processing apparatus in which a processing fluid is supplied to a nozzle, said processing fluid is applied upon a substrate through said nozzle and said substrate is accordingly subjected to a predetermined treatment, comprising: processing fluid feeding means which feeds said processing fluid toward said nozzle: a thermal type flowmeter which comprises a duct pipe of glass-like carbon, said thermal type flowmeter ensuring that at least a part of said processing fluid fed by said processing fluid feeding means flows through said duct pipe, said thermal type flowmeter measuring the flow rate of said processing fluid flowing through said duct pipe to thereby measure the flow rate of said processing fluid which is supplied to said nozzle; and control means which controls the amount in which said processing fluid is supplied to said nozzle, based on the result of measurement taken by said thermal type flowmeter, wherein a hole transporting material is applied upon said substrate as said processing fluid and a hole transporting layer is formed on said substrate.
