Abstract:
A coating apparatus, comprising:a holding member for holding a substrate; a nozzle provided with a plurality of discharge apertures in line for discharging a coating solution toward a top surface of the held substrate; a scanning mechanism for scan-moving said nozzle over the held substrate, an angle adjusting mechanism for adjusting an angle which is formed by a scanning direction of the nozzle scan-moved by said scanning mechanism and an arranging direction of the discharge apertures provided in line in said nozzle; means for inputting at least viscosity data of the coating solution and contact angle data of the substrate top surface; and means for calculating the angle formed by the scanning direction of said nozzle and the arranging direction of said discharge apertures based on the input data and adjusting the angle by means of said angle adjusting mechanism based on the calculation result.
