摘要:
A substrate to be processed on which a thin film is formed is supported by a support member. The substrate to be processed is heated by a heating section. The surface temperature is measured by a radiation thermometer, and the heating temperature of the heating section is controlled by a control section, in response to the temperature measured by the radiation thermometer. Further, a blackbody is provided at a position optically symmetrical to the radiation thermometer with respect to the surface of the thin film. The blackbody is set at a constant temperature. The blackbody cuts stray light (noise light) which enters into the radiation thermometer.

A dry etching method for organic material layers is disclosed which utilizes a parallel plate electrode type plasma etching apparatus. An etching gas containing nitrogen as its primary constituent is introduced into the apparatus, and then the organic material layers are anisotropically etched by applying a high frequency electric power to the electrodes to produce a plasma.

A flat film can be formed on a functional structure having uneven surface formed on a semiconductor substrate firstly by applying a film-forming organic material capable of being cured by energy beams and exhibiting fluidity by heat on the uneven surface of the functional structure. Then, the organic material is fluidized by applying heat to the applied organic material, thereby substantially flattening the surface of the organic material. Energy beams are irradiated to the flattened organic material to cure the flattened organic material, thereby converting the flattened organic material into a cured film which is not deformed by heat and energy beams.

An alignment mark formed on a surface of substrate for aligning with a mask through an irradiation of alignment light, which comprises a step formed with a concave portion and a convex portion and a metallic film deposited along the concave portion and the convex portion. A light absorption layer is formed over at least one of the concave portion and the convex portion reflecting the step, the light absorption layer lying over the concave portion having a different thickness from that of the light absorption layer lying over the convex portion when the light absorption layer is formed over both the concave portion and the convex portion, the light absorption layer comprising a material capable of absorbing at least a portion of wavelength region of the alignment light. The light absorption layer is desirably formed in a larger thickness on the convex portion of the step as compared with that on the concave portion. Desirably, the light absorption layer is a resist capable of absorbing a portion of wavelength region of the alignment light, or a resist containing a material capable of absorbing a portion of wavelength region of the alignment light.

In accordance with a proposed resist pattern forming method, contact angles between the surface of a resist and a rinse is adjusted within a predetermined range, a volatil surfactant which does not remain by drying is mixed in the rinse so as to reduce a surface tension, the rinse is dried under a critical condition of the rinse in order not to cause the surface tension to exert. The occurrence of an attractive force between the resist patterns may be thereby weakened or nullified, so that falling of the patterns can be effectively prevented which very often happened at forming fine resist patterns or resist patterns of high aspect. On the other hand, depending upon structure of said resist pattern, it is possible to effectively prevent outermost main patterns of gathering resist patterns from falling down. By providing such effects, yielding of products are increased. Further, the present invention may be also applied to a lithography illumination sources of which are light, electron, X-ray, ion beam, etc.
