In a method of removing a coating from an edge of a substrate a solvent reservoir is filled with a solvent to dissolve and remove a photoresist film, the solvent includes one of dipropylene glycol monoalkyl ether, a mixture of this ether and an easily volatile organic solvent (boiling point of 75-130.degree. C., vapor pressure of 5-75 mmHg at 20.degree. C.), and an alkaline aqueous solution, an edge of a substrate W is horizontally inserted in the reservoir, and thereafter, the edge of the substrate W is immersed in the solvent for a period of time, so as to dissolve and remove a coating such as photoresist from the edge of the substrate. The solvent may be filled into the solvent reservoir either before or after the edge of the substrate is inserted therein, and the method may further involve aspirating the solvent from the reservoir after the substrate edge has been inserted therein.

Proposed is a novel chemical-sensitization resist composition capable of giving a positively or negatively patterned resist layer of excellent pattern resolution and cross sectional profile of the patterned resist layer with high sensitivity. Characteristically, the resist composition is formulated, as combined with a resinous ingredient which is subject to changes in the solubility behavior in an alkaline developer solution by interaction with an acid, with a specific oximesulfonate compound as the radiation-sensitive acid-generating agent represented by the general formulaR.sup.1 --C(CN).dbd.N--O--SO.sub.2 --R.sup.2,in which R.sup.1 is an inert organic group and R.sup.2 is an unsubstituted or substituted polycyclic monovalent hydrocarbon group selected from the group consisting of polycyclic aromatic hydrocarbon groups such as naphthyl and polycyclic non-aromatic hydrocarbon groups such as a terpene or camphor residue.

Proposed is a novel undercoating composition to form an undercoating layer interposed between the surface of a substrate and a photoresist layer with an object to decrease the adverse influences by the reflection of light on the substrate surface in the pattern-wise exposure of the photoresist layer to ultraviolet light without the undesirable phenomena of intermixing between layers and notching along with a large selectivity ratio in the etching rates between the patterned resist layer and the undercoating layer in a dry-etching treatment. The undercoating composition comprises (A) an ultraviolet absorber which is a benzophenone compound or an aromatic azomethine compound each having at least one unsubstituted or alkyl-substituted amino group on the aryl groups and (B) a crosslinking agent which is preferably a melamine compound having at least two methylol groups or alkoxymethyl groups bonded to the nitrogen atoms in a molecule in a weight proportion (A):(B) in the range from 1:1 to 1:10.
摘要:
A proposal is made for the photolithographic formation of a patterned resist layer on a substrate without the troubles due to reflection of the exposure light on the substrate surface. Thus, patterning is conducted on a photoresist laminate comprising (a) a substrate; (b) a specific anti-reflection coating layer formed on one surface of the substrate; and (c) a photoresist layer formed on the anti-reflection coating layer from a specific negative-working chemical-sensitization photoresist composition comprising an oxime sulfonate acid generating agent. The patterning procedure comprises the steps of: (A) exposing, pattern-wise to actinic rays, the photoresist layer of the photoresist laminate; (B) subjecting the photoresist layer to a heat treatment; (C) subjecting the photoresist layer to a development treatment to dissolve away the photoresist layer in the areas unexposed to actinic rays in step (A) so as to expose bare the anti-reflection coating layer in the areas unexposed to the actinic rays leaving a patterned resist layer in the areas exposed to the actinic rays; and (D) removing the pattern-wise exposed anti-reflection coating layer by dry etching with the patterned photoresist layer as a mask.

A disc defect inspection apparatus which can detect a defect of a disc, such as an optical disc, with high accuracy. A disc defect inspection apparatus includes a rotating portion for rotating a disc, laser radiating optical portion for radiating laser lights on the disc rotated by the rotating portion under predetermined scanning conditions, sensors for detecting reflected laser lights from the disc, and a memory in which output signals of the sensors are stored together with address data generated in unison with the scanning of laser lights. Sensor outputs indicative of address positions of the disc are stored in the memory and sensor outputs near the address positions are read out and a defect of the disc is detected on the basis of a spatial difference among the nearby sensor outputs and the sensor output of the center address position.

Disclosed is a novel and improved photoresist composition which comprises: (A) a film-forming resinous compound which is, in the presence of an acid, subject to a change in the solubility in an alkaline solution; and (B) an acid-generating agent capable of releasing an acid by the exposure to actinic rays which is an oxime sulfonate compound represented by the general formula NC--CR.sup.1 .dbd.N--O--SO.sub.2 --R.sup.2, in which R.sup.1 and R.sup.2 are, each independently from the other, an unsubstituted or halogen-substituted monovalent aliphatic hydrocarbon group, e.g., alkyl, cycloalkyl, alkenyl and cycloalkenyl groups. By virtue of the non-aromatic nature of the component (B) as well as good solubility thereof in organic solvents and high acid strength of the acid released therefrom, the composition is highly transparent to deep ultraviolet light even when the content of the component (B) is relatively large and the photosensitivity of the composition is very high so that the photoresist composition is capable of giving a patterned resist layer having excellent characteristics.
