Patent ID: 7079994

Claim:
A method of producing a semiconductor device upon receiving an order for the semiconductor device by transferring information between a person who wishes to receive an order and a person who wishes to place an order through a network, the method comprising: receiving, from a person who wishes to place an order, a plurality of specifications of the semiconductor device; generating a plurality of circuit patterns based on at least one of the specifications of the semiconductor device, the circuit patterns including a circuit pattern generated by using a stored character projection (CP) aperture for charged-particle beam exposure and a circuit pattern generated by using the stored CP aperture and a CP aperture to be newly produced, and obtaining a plurality of design parameters for each of the circuit patterns, and calculating a cost and a delivery time period for each of the circuit patterns, the cost including a cost for producing the CP aperture to be newly prepared; presenting said plurality of design parameters with the associated cost and the associated delivery time period for each of the circuit patterns to the person who wishes to place an order for each of the circuit patterns; and providing the semiconductor device to the person who wishes to place an order when at least one of the plurality of design parameters with the associated cost and the associated delivery time satisfies a desired condition.
