Tape-out system of mask tooling network for multiple supply chain

A method of a tape-out system of a mask tooling network for multi-users, the steps of the method comprising:

• providing an integrated circuit (IC) designer computer, a design service computer, a mask house computer, wherein the IC designer computer, the design service computer and the mask house computer are linked by a network;
• requesting a mask tooling of a product from the IC designer computer, wherein a data of the mask tooling is transmitted to the design service computer;
• performing a processing step and a summarizing step with an electronic signature to process the mask tooling data from the design service computer;
• transmitting a signal from the design service computer to notify the mask house computer and the IC designer computer to process and summarize the mask tooling data;
• and
• transmitting a signal of the electronic signature to the design service computer after the mask house computer and the IC designer computer process the mask tooling data.
