摘要:
When a conventional semiconductor container opening/closing apparatus opens a lid of a semiconductor container, foreign particles enter into the container from outside through a gap between the container and a wall surface of the container opening/closing apparatus and adhere to a wafer in the container. An apparatus is provided to reduce the number of foreign particles adhering to the wafer by preventing foreign particles from entering into the container at the time of opening the container by the opening/closing apparatus. To achieve this, a velocity-differential pressure ratio obtained by dividing the maximum velocity at the time of opening the lid of the container in a vertical direction to an opening of the container, by the differential pressure between the inside pressure and the outside pressure of said semiconductor manufacturing apparatus, is set to be 0.06 ((m/s) Pa) or less.

A method is provided of manufacturing semiconductor devices formed on a semiconductor wafer, including placing the wafer in a semiconductor container and conveying the container to a semiconductor manufacturing apparatus. An opening of the container is opposed to an opening of the apparatus such that an opener of the apparatus holds a lid of the opening the container. A key of the opener is inserted to a latch groove of the lid, and the key is rotated to contact a latch of the lid. The openings are connected such that a velocity differential pressure ratio obtained by dividing the maximum velocity when the opener holding the lid horizontally moves away from the opening of the container, by the differential pressure between the inside pressure and the outside pressure of the apparatus, is set to be 0.06 ((m/s)/Pa) or less, and then the wafer is processed.

To provide a semiconductor integrated circuit device having improved reliability. An EFEM unit upstream of a plasma processing unit is equipped with a chemical filer for alkali removal. In the plasma processing unit, a semiconductor wafer is subjected to plasma processing with a gas containing fluorine. The resulting semiconductor wafer is put in a carrier via a transfer chamber, load lock chamber and EFEM chamber. During this operation, the concentration of amines in the EFEM chamber is adjusted to be lower than that of amines in a clean room outside the chamber by a chemical filter.

A FOUP having semiconductor wafers received therein is transferred to a loading port and then the door of the FOUP is fixed and removed by a FIMS door and then the semiconductor wafers are taken out of the shell of the FOUP and then a predetermined manufacturing processing is performed to the semiconductor wafers. After performing the manufacturing processing, the semiconductor wafers are returned into the shell and the FIMS door is returned to a closed position and the shell is retracted about 50 mm to 65 mm to form a gap between the FIMS door and the shell. Then, purge gas is introduced from a gas introduction pipe arranged above the loading port on the left and right sides in a slanting forward direction of the FIMS door into the shell to replace the atmosphere in the shell with the purge gas.

In a load port mechanism of a substrate treatment unit, protuberances are provided on a sealing surface formed along a door with which a wafer carrier is to dock, or on a sealing surface formed around the door of the wafer carrier. The wafer carrier door is faced with the load port door with the protuberances therebetween, thereby separating the sealing surface of the substrate treatment unit from the sealing surface of the wafer carrier by only a predetermined distance. Thus, there is formed a channel along which clean air flows from the inside of the substrate treatment unit to the outside thereof. The load port structure and the wafer carrier structure improve the reliability of opening/closing action of the wafer carrier and prevent entry of extraneous particles into the treatment unit with sufficient reliability, and enable high-yield production of integrated circuits.
