- Each of the manufacturing apparatuses 1 1 0 — 1 to 1 1 0 — 1 4 is provided with a semiconductor substrate loading section (loader section) 1 1 1 1 and a semiconductor substrate unloading section (part of the unloader) 1 1 2. .
- Semiconductor substrate loading section 1 1 1 Is a part where the semiconductor substrate is put into the manufacturing apparatus, and the semiconductor substrate discharging part 112 is a part where the semiconductor substrate processed by the manufacturing apparatus is discharged. Only the input section 11 1 and the output section 1 12 are exposed from the utility area 120 to the parking area 130. Then, in the working area 130, each semiconductor substrate is transported, and in some cases, various operations are performed by humans.
- the clean room is divided into areas requiring high cleanliness (working areas) and areas not requiring such cleanliness (utility areas) in order to thoroughly control cleanliness. That is common.
- each manufacturing equipment 110-1 to 110-14 is shown in Fig. 1. Such a side-by-side arrangement. Then, the working area 130 becomes a passage.
- the semiconductor substrate after processing in (1) above has the same cassette as before processing.
- a charging section and a discharging section are provided on the front of the manufacturing apparatus so as to form a pair.
- a cassette in which the same semiconductor substrate is set before and after processing is generally called a cassette.
- a manufacturing device operated using a tunica set is provided with one or more input sections and pay-out / use ports in front of the manufacturing device.
- the same transport box for storing cassettes is usually used before and after processing.
- the transport box containing the semiconductor substrate processed by the manufacturing apparatus 110-112 is set in the input unit 111 of the manufacturing apparatus 110-3.
- An empty transport box is set in the dispensing section 1 1 2 of the manufacturing apparatus 1 1 0 3.

- the above-described method of handling semiconductor substrates degrades the efficiency of cleanliness management of the entire clean room, and also complicates the operation and management of the transport box. is there. That is, the required cleanliness of the transport box varies depending on each process. For example, since the resist is applied to the semiconductor substrate between the etching step and the resist stripping step, the purity of the transfer box for transferring the semiconductor substrate between the two steps may be relatively low. In contrast, the cleaning process Transport boxes used during the membrane process require extremely high cleanliness.
- the inside of the peaking area 130 contains a semiconductor substrate to be maintained with high cleanliness, a semiconductor substrate with a resist or a reactive gas attached, And transport boxes and cassettes that store them, as well as empty transport boxes and cassettes. Since transport boxes with different degrees of cleanliness come and go in one place, it is difficult to efficiently manage cleanliness in the clean room. Furthermore, since the transport boxes of various cleanliness are disturbed in the working area, the operation management becomes complicated and complicated.
- the transport box needs a management tag that indicates information on the semiconductor substrates stored in the box and information on the current processing stage.
- the transport box is replaced each time the processing is performed in the manufacturing equipment. For this reason, it is necessary to transfer the management tag of the transport box supplied to the input section to the transport box prepared in the output section. Also in this aspect, the management of the transport box becomes complicated.

Therefore, the management of the transport box can be simplified because no empty box is generated, and the problem of the management tag can be solved.However, when a tunica set is used, the cleanliness in the transport box can be reduced. There is a problem that maintenance becomes difficult. For example, a resist is applied to a semiconductor substrate after a lithography process. I have. Doing so may cause this register to adhere to the cassette. Further, it is assumed that etching is performed in the next step by, for example, a dry etching apparatus. Then, the degassed reactive gas adhering to the semiconductor substrate by dry etching is adsorbed to the cassette.
- Ni will this Yo, when sequentially performing the process, then t the chemical solution or gas or the like used in the process each time is attached to the transport box, the semiconductor substrate by performing a registry removal and cleaning of the semiconductor substrate Even if it is cleaned, the cleanliness of the semiconductor substrate will deteriorate because the inside of the transport box is contaminated with the resist or the reactive gas. As described above, when a unit set is used, there is a problem that the transport box and the cassette are contaminated every time the processing proceeds, and the semiconductor substrate is contaminated accordingly. The installation layout of another manufacturing device in the clean room will be described with reference to FIG.

It is classified as a high cleanliness transport pot that requires high cleanliness. Then, the working areas 13 0 — 1 to 13 0 — 3 move in and out of the transport box with each cleanliness. Zone.
- the transfer control of the transfer box is easy and the control tag is moved. It has the advantage that it is not required.

Since the area where the space is used is limited, each transport box can be managed for each cleanliness, and the transport management of the transport box and the cleanliness management in the clean room can be simplified. In other words, transport boxes of each degree of cleanliness are basically not transported out of the area, so operation with a dedicated transport box is possible. Further, the transfer distance of the transfer potus can be shortened, and the transfer path can be simplified.
