Abstract:
1. A temperature calibration method for a baking processing apparatus, comprising: forming a photosensitive resin film onto a substrate; preparing an exposure mask having a mask pattern for a dose monitor mark to monitor an effective dose on the substrate; forming a latent image of the dose monitor mark by using an exposure apparatus to transfer the mask pattern for the dose monitor mark onto the photosensitive resin film at a predetermined dose; preparing baking processing apparatuses; baking the substrate, on which the latent image is formed, at a predetermined temperature by using each of the baking processing apparatuses; cooling the baking-processed substrate; measuring a length of the latent image of the dose monitor mark obtained by a developing process; determining a relationship between a temperature setting and an effective dose; and calibrating the temperature setting of each of the baking processing apparatuses to obtain a predetermined effective dose based on the determined relationship and the measured length corresponding to each of the baking processing apparatuses.
