Abstract

PURPOSE:To prevent film remains existing at the stepped section of a foundation of the film by forming a two-layer structure in which a thin resist is used as a lower layer and an Al film, a Cu film or an SiO2 film shaped through a vacuum thin-film forming method as an upper layer. CONSTITUTION:A resist as a lower layer is formed onto a pattern with stepped sections in 4mum, 8mum and 12mum thickness through a spinner spin coating method. Film thickness at that time is brought to approximately 3mum in a flat section. An Al, Cu or SiO2 upper layer film is shaped through a vacuum thin-film forming method. The resist is applied on a flat surface in approximately 0.3mum, and the upper layer and the lower layer are etched through RIE, thus forming a pattern for a lift-off. Consequently, a pattern forming process for the lift-off is completed. A resist pattern for etching the upper layer is removed approximately on the etching of the upper layer. Film thickness can be made approximately the same as thickness in the flat section even at the stepped sections in the pattern for a lift-off method shaped through such a forming method.

The present invention is a resist applied thinly to the lower layer in a lift-off pattern structure! I is formed on the upper layer by vacuum thin film formation method, and vh is 0% film, and vh is 8jOm I.
The pattern film thickness t for the lower part of the stepped part and the adhesive part of the support part 7 is formed to be approximately equal, and this pattern is used to form the film so that there is no remaining film at the stepped part of the 9 films. Since the lift-off is performed on the lower resist film, it can be performed easily like a conventional lift-off.

[One point while the invention is trying to solve it] However, in the above-mentioned conventional technology, when there is a step part in the base layer, the resist accumulates at the bottom of the step, and the thickness at the bottom becomes hidden edge compared to other flat parts. If you use a pattern like this, it will become thicker, and if you use a pattern like this, it will become thicker.
As shown in FIGS. 3 and 4, a problem arose in that a film remained after lift-off.
