Claim:
1. A substrate processing device comprising: a cleaning liquid supply unit supplying a cleaning liquid to a surface with a pattern of a substrate; a solvent supply unit supplying a liquid volatile solvent to the surface of the substrate supplied with the cleaning liquid to replace the cleaning liquid on the surface of the substrate with the liquid volatile solvent; a heating unit heating the substrate supplied with the volatile solvent and producing droplets of the volatile solvent on the surface with the pattern of the substrate by a heating operation of the heating unit, a drying unit drying the surface of the substrate by removing the droplet, and a transport roller transporting the substrate, wherein the heating unit has a lamp irradiating the substrate with light having a peak intensity in wavelengths between 500 nm and 3000 nm, the drying unit is a suction drying unit comprising a vacuum pump and a solvent suction port to remove the droplet of the volatile solvent from the surface of the substrate, the heating unit and the solvent suction port are provided being along the substrate transporting direction by the transport roller, and facing the surface with the pattern of the substrate transported by the transport roller, the solvent suction port is located downstream from the heating unit and is adjacent to it, and wherein the solvent suction port has a substantially equal width to the width of the substrate on the transport roller.
