Patent ID: 7867671

Claim:
A photo-mask comprising: a first light shielding region being narrow and elongated, the first light shielding region corresponding to a first circuit pattern and being for use in manufacturing the first circuit pattern; a second light shielding region being elongated and wider than the first light shielding region and being distant from the first light shielding region, the second light shielding region corresponding to or wider than a second circuit pattern and being for use in manufacturing the second circuit pattern; a first light transmitting region being arranged on a first side of the first light shielding region and being provided with a-first one of a first phase shifter part and a first non-phase shifter part, the first phase shifter part shifting the phase of a transmitted light by zero degrees and the first non-phase shifter part shifting the phase of the transmitted light by 180 degrees; a second light transmitting region being arranged between a second side of the first light shielding region and a first side of the second light shielding region, the second light transmitting region being provided with the other one of the first phase shifter part and the first non-phase shifter part; and a third light transmitting region being arranged on a second side of the second light shielding region and being provided with one of a second phase shifter part and a second non-phase shifter part which shifts the phase of the transmitted light by the same degree as that of the other one of the first phase shifter part and the first non-phase shifter part, the second phase shifter part shifting the phase of a transmitted light by zero degrees and the second non-phase shifter part shifting the phase of the transmitted light by 180 degrees.
