摘要： 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.

摘要： While it is important in the photolithographic patterning of a photoresist layer on a substrate surface for the manufacture of various electronic devices that the pattern-wise light exposure of the photoresist layer is preceded by partial removal of the photoresist layer on the non-patterning areas such as marginal areas, peripheral areas and back surface opposite to the surface for resist patterning by dissolving away the extraneous photoresist layer with a remover solvent, the invention proposes an improvement in the partial removal of the photoresist layer by using a specific organic solvent or solvent mixture selected relative to the surface tension of the solvent which, in particular, is a mixture of .gamma.-butyrolactone and anisole in a mixing ratio of 70:30 to 97:3 by weight.

摘要： Conventional detergents for lithography which contain a surfactant as an active ingredient should have a reduced surfactant concentration because heightened surfactant concentrations result in dissolution of the resin component of a photoresist composition and hence in a dimensional change of a resist pattern. However, the conventional detergents have had a drawback that such a low concentration unavoidably reduces the ability to inhibit pattern falling and defect occurrence. A detergent for lithography is provided which is an aqueous solution containing (A) at least one member selected among nitrogenous cationic surfactants and nitrogenous ampholytic surfactants and (B) an anionic surfactant. This detergent retains a low surface tension even when it has a low concentration. It is effective in inhibiting pattern falling and defect occurrence. It can also inhibit resist patterns from fluctuating in dimension.
