Abstract:
A pattern forming method includes: (a) forming a first film on a substrate using an actinic ray-sensitive or radiation-sensitive resin composition (I) containing a resin of which solubility in a developer containing an organic solvent decreases due to polarity increased by an action of an acid; (b) exposing the first film; (c) developing the exposed first film using a developer containing an organic solvent to form a first negative pattern; (e) forming a second film on the substrate using an actinic ray-sensitive or radiation-sensitive resin composition (II) containing a resin of which solubility in a developer containing an organic solvent decreases due to polarity increased by an action of an acid; (f) exposing the second film; and (g) developing the exposed second film using a developer containing an organic solvent to form a second negative pattern in this order.

PROBLEM TO BE SOLVED: To provide an impurity layer, with a predetermined size and pattern. SOLUTION: A semiconductor substrate 11 is coated with a resist 42 having a thickness of ≥2 μm. The resist 42 is subjected to a first exposure, by using an exposure mask having a first stripe pattern (pattern of lateral stripes arranged at predetermined intervals). Thereafter, the resist 42 is subjected to a second exposure using an exposure mask having a second stripe pattern (pattern of longitudinal stripes arranged at predetermined intervals); by using a resist mask 55 obtained by double exposure, p-type ions are implanted; and inter-pixel separation areas 33 that separate pixels are thereby formed at a deep position in the semiconductor substrate 11.
