Abstract:
A method of manufacturing a semiconductor device comprising:forming a first thin film on a main surface of a semiconductor substrate having an alignment mark; applying a first energy beam to said first thin film provided on a region containing said alignment mark to selectively remove part of said first thin film; supplying a chemical containing both a light sensitive material and a solvent onto said first thin film to provide a coating film thereon; removing said solvent contained in said coating film to form a light sensitive thin film; carrying said semiconductor substrate to latent image forming means and irradiating said positioning mark with a reference beam through a region in which said first thin film is selectively removed, thereby to recognize a position of said alignment mark; irradiating a predetermined position on said light sensitive thin film with a second energy beam based on the position of the recognized alignment mark to form a latent image on the light sensitive thin film; and forming a light sensitive thin film pattern by removing at least part of said light sensitive thin film based on the latent image formed on said light sensitive thin film, wherein upon irradiating the first energy beam, liquid is supplied to at least a region irradiated with first energy beam.
