Imprint apparatus

An article manufacturing method for manufacturing an article from a processed substrate, the article manufacturing method comprising:

• a step of forming a pattern of an imprint material on a substrate using a mold by using an imprint apparatus including:
• a supplying unit configured to supply the imprint material onto the substrate;
• an energy supplying unit configured to supply energy for increasing a degree of polymerization to the imprint material on the substrate;
• a moving unit configured to move at least one of the mold and the substrate;
• and
• a controller programmed to perform:
• a first supplying step of supplying the imprint material onto at least a first region in a predetermined shot region on the substrate by the supplying unit, the first region being determined based on information on a distortion of the substrate caused by a deviation in flatness of a surface of the substrate;
• a first energy supplying step of supplying the energy to the imprint material supplied onto the first region by the energy supplying unit so as to increase the degree of polymerization of the imprint material supplied onto the first region, without fully curing the imprint material supplied onto the first region;
• a second supplying step of supplying the imprint material onto a second region other than the first region in the predetermined shot region by the supplying unit after performing the first energy supplying step;
• a moving step of moving at least one of the mold and the substrate by the moving unit such that a pattern region formed on the mold and the imprint material on the substrate are brought into contact with each other, after performing the second supplying step;
• and
• a second energy supplying step of supplying the energy to the imprint material supplied onto the predetermined shot region by the energy supplying unit such that the imprint material supplied onto the predetermined shot region is solidified after the pattern region and the imprint material on the substrate are brought into contact with each other;
• and
• a step of processing the substrate on which the pattern is formed.

A method of controlling an imprint apparatus via a programmed controller to form a pattern of an imprint material on a substrate using a mold, the imprint apparatus including a supplying unit configured to supply the imprint material onto the substrate, an energy supplying unit configured to supply energy for increasing a degree of polymerization to the imprint material on the substrate, and a moving unit configured to move at least one of the mold and the substrate, the method comprising:

• a first supplying step of supplying the imprint material onto at least a first region in a predetermined shot region on the substrate by the supplying unit, the first region being determined based on information on a distortion of the substrate caused by a deviation in flatness of a surface of the substrate;
• a first energy supplying step of supplying the energy to the imprint material supplied onto the first region by the energy supplying unit so as to increase the degree of polymerization of the imprint material supplied onto the first region, without fully curing the imprint material supplied onto the first region;
• a second supplying step of supplying the imprint material onto a second region other than the first region in the predetermined shot region by the supplying unit after performing the first energy supplying step;
• a moving step of moving at least one of the mold and the substrate by the moving unit such that a pattern region formed on the mold and the imprint material on the substrate are brought into contact with each other, after performing the second supplying step;
• and
• a second energy supplying step of supplying the energy to the imprint material supplied onto the predetermined shot region by the energy supplying unit such that the imprint material supplied onto the predetermined shot region is solidified after the pattern region and the imprint material on the substrate are brought into contact with each other.
