Benefits of technology

The technical effect of this patent is that it provides a way for managing inventory and accurately figuring out what products can be made based on customer orders. This expands options for sales and helps companies make more money.

Problems solved by technology

The technical problem addressed in this patent text is how to accurately estimate the progress of lots in a semiconductor fabric during production without relying solely on computer simulations. This is important for ensuring efficient production planning and execution, particularly in smaller fabs who have limited resources available. Existing solutions rely on approximations made based on factors such as process duration and apparatus groupings, leading to difficulty in accurately estimating the status of individual lots.

first embodiment

[0070] (First Embodiment)

[0071]FIG. 2 is a block diagram showing an entire configuration of an electronic commerce system for semiconductor products according to a first embodiment of the present invention.

[0072] A network 10 is a computer network such as Internet. The system implements an electronic commerce via this network 10.

[0073] The network 10 connects with a plurality of client terminals 11 and a connection server 12. The client terminal 11 is operated by a customer such as a user or a sales representative and can be an Internet-connectable personal computer or mobile telephone. The connection server 12 connects with a virtual factory (virtual production line) 13 referred to as a mini-fab. The connection server 12 exchanges various data between the client terminal 11 and the virtual factory 13. The virtual factory 13 is connected to a real factory 14 as a mini-fab which actually manufactures semiconductor products as will be described later. The virtual factory 13 is imple...

second embodiment

[0102] (Second Embodiment)

[0103]FIG. 11 is a block diagram exemplifying a semiconductor production system according to a second embodiment of the present invention.

[0104] There is provided a manufacturing apparatus group in the real factory 14 (real production line) which actually manufactures semiconductor products including trial products. Products flow along each real production line in this real factory 14. A computer in the real factory 14 manages a lot progress of each product. For example, a proper operation on the computer screen allows to determine which apparatus processes a given lot, whether the lot is being processed, waits for processing, or is being transported. In addition to lot progress data, the computer stores information about apparatus states such as active, idle, being maintained, failed, scheduled to be maintained, and the like.

[0105] Various information in the real factory 14 is manually or automatically transferred to the virtual factory 13 (virtual produ...

third embodiment

[0134] (Third Embodiment)

[0135] This embodiment concerns a modification of the second embodiment.

[0136] The second embodiment described the cases for finding optimal processes according to purposes of processing a high-priority lot in a short work period and preferentially processing a lot subject to no or little effect of the maintenance. The third embodiment finds an optimal process for achieving an object to perform processing so that electric power does not exceed a preset value.

[0137]FIG. 18 shows a configuration of the virtual factory 13 capable of electric power (or power usage) leveling. FIG. 18 differs from FIG. 12 in that the apparatus's electric power or power usage information and the electric power or power usage condition are added as input data. FIGS. 19 and 20 provide example data representing profiles and conditions of the electric power or power usage for apparatuses. This embodiment exemplifies power restrictions. The fourth embodiment exemplifies power usage re...

Abstract

An electronic commerce for semiconductor products comprises a network, a client terminal, a connection server, a virtual production line, and a real production line. The real production line actually manufactures semiconductor products. The virtual production line provides a computer with substantially the same functions as the real production line and computes an optimal lot progress. The connection server connects the virtual production line to the client terminal via the network. When a condition is entered from the client terminal, the connection server transfers this condition to the virtual production line. Simulation is performed realtime for determining whether a product flows in the virtual production line under the transferred condition. The connection server transfers a simulation result to the client terminal. Based on the simulation result, a electronic commerce is conducted.
