摘要:
A method of moving an object comprises a step of fixing the object to an object-moving means, a step of moving the object to a prescribed position by the object-moving means, and a step of releasing the object from the object-moving means; wherein the fixing step comprises forming a deposit, for fixation of the object to the object-moving means by applying a first corpuscular beam in a first gas to form a deposit; and the releasing step comprises etching the deposit by applying a second corpuscular beam in contact with a second gas.
