    摘要: 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.

    摘要: An exposure method of sequential beam, contributing to the improvement of alignment accuracy at connecting portion at the end part of an exposure region, as well as pattern dimension accuracy is provided. The method comprises the steps of dividing an area to be exposed into a plurality of fields each being determined by the deflection width of the main deflector, dividing each field into a plurality of sub-fields each being determined by the deflection width of the sub-deflector, applying a sequential exposure process to each field by using a variable shaped electron beam, and applying a multiple exposure process to an area where adjacent fields overlap each other, wherein the multiple exposure process is conducted in the area in units of sub-field, the exposure dose at each of exposure unit is determined such that the total exposure dosage in the area subject to the multiple exposure process is set equal to an exposure dosage used when single exposure process is applied, the exposure dosage in the area subject to multiple exposure process is decreased in steps, in the direction perpendicular to the longitudinal direction of the boundary portion from the outer edge of the field towards the outside of the field, an exposure dosage in the area subject to the multiple exposure process is determined using the minimum exposure dosage available in the exposure apparatus as the lower limit.

    摘要: 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.

    摘要: 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.
