Abstract

PURPOSE: To ensure the assured lift-off even with the thin resist film by using the resist film and poly Si film together, and thus to secure the remains of the uniform poly Si thin film even with etching of the poly Si.
CONSTITUTION: The opening is provided to SiO2 on Si substrate 1 to form poly Si thin film 1', and then poly Si1', SiO22' and poly Si1" are formed continuously through the CVD method. The gas etching is given via CF4 after formation of resist mask 3, and the etching is stopped at film 2'. Thin film 2' is then removed by being soaked into the HF-group solution. Then Al electrode 4 is evaporated, and film 3 is fused to lift off film 4. And the plasma etching is applied to film 1", 2' and 1' respectively via mask 4.
