Assignee: KABUSHIKI KAISHA TOSHIBA
Field: Semiconductors (Electrical engineering)
Classification: CPC H  G  Y | IPC G  H

Claim 4:
5. A manufacturing control method of controlling an output value of an intermediate product of a semiconductor device produced in each of a plurality of manufacturing processes of a semiconductor manufacturing apparatus, the manufacturing control method comprising:
acquiring past manufacturing data in which a target value of an output value of the intermediate product, the output value of the intermediate product, and quality of the semiconductor device being a final product produced from the manufacturing apparatus are associated with each other;
predicting, based on the target value of the intermediate product and the output value of the intermediate product in the past manufacturing data, the output value of the intermediate product for each of possible target values of the intermediate product;
predicting, based on the output value of the intermediate product and the quality of the final product in the past manufacturing data, the quality of the final product from a predicted value of the output value of the intermediate product for each of the possible target values predicted in the predicting the output value;
controlling a processing condition of a processing apparatus in each of the plurality of manufacturing processes to make the output value of the intermediate product closer to a target value, and
determining, from the plurality of possible target values and based on a predicted value of the quality of the final product for each of the plurality of possible target values, the target value of the intermediate product associated with a best predicted value of the final product, wherein
the quality of the final product includes at least one of shape, size or property of the final product, and
the target value of the intermediate product includes a numerical value of at least one of shape, size or property of the intermediate product.
