Patent ID: 7141120

Claim:
A manufacturing system of a semiconductor device, comprising: a first manufacturing apparatus; a second manufacturing apparatus; a third manufacturing apparatus, wherein each of the first, second, and third manufacturing apparatus comprises: an introducing section, a process section having a surface, the introducing section being provided on the surface of the process section, and a withdrawing section which is arranged on a surface of the process section differing from the surface on which the introducing section is arranged; a first plurality of transfer boxes associated with a first region including the introducing section of the second manufacturing apparatus and the withdrawing section of the first manufacturing apparatus; a second plurality of transfer boxes associated with a second region including the withdrawing section of the second manufacturing apparatus and the introducing section of the third manufacturing apparatus; a first transfer box being selected from the first plurality of transfer boxes, the first transfer box having a first environment therein, a second transfer box being selected from the second plurality of transfer boxes, the second transfer box having a second environment therein, wherein a third environment surrounds at least one of the first, second, and third manufacturing apparatuses, the introducing section of the second manufacturing apparatus being configured to introduce the first transfer box holding the semiconductor substrate therein, the process section of the second manufacturing apparatus being configured to apply a process to the semiconductor substrate, the withdrawing section of the second manufacturing apparatus being configured to withdraw the second transfer box holding the semiconductor substrate after the semiconductor substrate has been discharged from the process section of the second manufacturing apparatus, and wherein the first environment has a cleanliness higher than the third environment while the semiconductor substrate is held in the first transfer box, and the second environment has a cleanliness higher than the third environment while the semiconductor substrate is held in the second transfer box.
