Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a system for developing and manufacturing semiconductor products manufactured through a number of manufacturing processes. In particular, the present invention relates to a product such as an electronic device which is combined by combining a circuit including a plurality of transistors, typically, an EL (electroluminescence) display module, a liquid crystal display module, and other display modules (such as a display panel). Terminals into a module).
[0002]
[Prior art]
2. Description of the Related Art In recent years, semiconductor technology used for electronic devices such as mobile phones and personal computers has been remarkably developed, and technological innovation of semiconductor technology has been performed in a short period of time. Therefore, the life cycle of an electronic device is very short, and it is not unusual for a product to be switched in a few years, and in some cases about one year. In order for a single company to do everything from technology development to design, manufacturing, and sales of such electronic equipment with a very short life cycle, it is necessary to invest large amounts of money in development costs, human resources, manufacturing equipment, etc. And it was difficult to diversify the risks.
[0003]
In the field of LSI, a manufacturing system that divides a system design and a manufacturing process is implemented to solve such a situation. Specifically, it is described in “Nikkei Microdevices, April 2001, p. 156-157”, but a design company without a factory (hereinafter referred to as fabless) designs ICs, and then The mask shop manufactures the mask, then the Si foundry manufactures the wafer, then the assembly house performs the assembly, and then the test house performs the inspection. FIG. 1 of Japanese Patent Application Laid-Open No. 14-025876 describes a flowchart in which the manufacturing process is divided by a designer, each company, and a user.
[0004]
Such a horizontal division of labor-only manufacturing system in the LSI field has a high decision-making ability and is well-versed in and specialized in specialized businesses, and therefore has high growth and profitability.
[0005]
[Problems to be solved by the invention]
However, in the field of the liquid crystal display module, the EL display module, and other display modules, the manufacturing process is not divided as in the LSI field. Therefore, it is necessary to invest a large amount of funds in development costs, human resources, manufacturing equipment, and the like, and this involves considerable risks, and these risks could not be dispersed.
[0006]
Also, in the field of display modules, unlike the field of LSIs that merely constitute circuits, in the field of display modules, inconsistencies arise in the manufacturing process. Hereinafter, the contradiction in the manufacturing process will be described.
[0007]
FIG. 16 shows a rough manufacturing process in the field of the display module, a process of determining the specifications of the display module, a process of designing a circuit or the like based on the specifications, a pixel circuit having a transistor based on the design, A step of forming a substrate (hereinafter, referred to as an active matrix substrate) provided with a driver circuit and other integrated circuits (hereinafter, referred to as a circuit), and forming a light-emitting element or a liquid crystal element on the active matrix substrate to perform display. Completing the module.
[0008]
In the process of forming the active matrix substrate, it is manufactured to prevent physical contamination by dust, chemical contamination of phosphorus, boron, organic gas, etc., and chemical contamination of metals such as iron, nickel, sodium, etc. or alkali metals. Although it is necessary to clean the environment, the light emitting element and the liquid crystal element constituting the display module require an alkali metal or an alkaline earth metal as a constituent material. Therefore, producing such a composite product on an integrated production line would result in a practical inconsistency, requiring a great deal of labor and capital investment.
[0009]
Furthermore, in order to differentiate itself from competitors, there is a way to differentiate it in terms of price, but it is possible to occupy the market share more advantageously. In order to occupy the market share more advantageously, it is necessary to improve the function or performance and to constantly supply new products to the market. To that end, intellectual property rights (including patent rights, utility model rights, design rights, trademark rights, copyrights, and circuit layout usage rights) relating to developed technologies such as higher functionality, higher performance, new manufacturing technologies, etc. ) Was urgently needed.
[0010]
Therefore, an object of the present invention is to provide a manufacturing system in which the manufacturing process in the field of the display module is divided (division of labor) by several designers and manufacturers, specifically, companies or corporations, and risk is dispersed. . It is another object of the present invention to provide a manufacturing system in which a manufacturing process of a product such as a display module protected by intellectual property rights is divided.
