  • Patent number: 12243762
    Abstract: A door locking mechanism and semiconductor container using the same include door panel, cover, and locking module. The door panel has a first stop structure. The cover and the door panel define an accommodating space for receiving the locking module. The locking module includes rotating member, holding member, and elastic member. The elastic member is disposed on the holding member and has a second stop structure near the first stop structure. The elastic member is disposed between the holding and the rotating member. The elastic member is compressed when a force is applied to the holding member, and the second stop structure detaches from a limitation state with the first stop structure for allowing a rotating operation of the rotating member. The elastic member elastically restores when the force is removed, and the second stop structure returns to the limitation state for limiting the rotating operation.

  • Patent number: 9817306
    Abstract: The present invention relates to an EUV pod having marks, which comprises a mask pod and one or more mark disposed on the mask pod. One or more sensor of a processing machine is used for detecting the one or more mark. By including the one or more mark, the surface roughness of one or more region of the mask pod detectable by the one or more sensor can be altered. The one or more sensor emits light to the mask pod, which reflects the light to the one or more sensor. The one or more sensor receives the reflection light from the mask pod and judges if the voltage generated by the reflection light falls within the reflection ranges of the mark. Thereby, whether the one or more sensor corresponds to the one or more make can be confirmed.

  • Patent number: 9396980
    Abstract: The present invention provides an anti-electrostatic cassette, which mainly comprises at least an electrostatic discharge (ESD) device connected electrically to the carrying frames, which are disposed in the substrate cassette and carry the substrates, and to the handles, which are disposed on the outer sides of the substrate cassette, for forming the conductive path. By means of the contact between the equipment and the two handles of the substrate cassette, the residual static charges on the substrates are conducted to the ground for reducing the residual static charges on the substrates. Consequently, the ESD phenomena in the substrates due to friction can be avoided and hence preventing the damages in the substrates caused by static charges.

  • Patent number: 9230839
    Abstract: The present invention relates to a reticle pod having gas guiding apparatus. The gas guiding apparatus communicates with at least an inlet of the reticle pod and comprises a first outlet corresponding to a first gas flowing space of the reticle pod and a second outlet corresponding to a second gas flowing space. When the inlet supplies a high-purity gas to the gas guiding apparatus, the high-purity gas will flows through the gas guiding apparatus, and flow to the first and second gas flowing spaces via the first and second outlets, respectively to distribute uniformly in the first and second gas flowing spaces. In addition, the cleaning efficiency on the reticle is improved; the contact between the reticle and air can be avoided for protecting the reticle. Thereby, the usage of the high-purity gas is reduced, and the filling efficiency of the high-purity gas is enhanced.

  • Patent number: 9091353
    Abstract: A gas charging check valve uses a first elastic element and a second elastic element, which respectively provide elastic force on a top valve and a bottom valve. The top valve and the bottom valve correspond to each other as a set. When the gas charging device is moved to apply an external force on a movement control portion of the gas charging check valve, the second elastic element removes the elastic force applied on the bottom valve to reduce the required gas inject force for a valve formed by the top valve and the bottom valve, so that the gas can more easily enter the valve.

  • Patent number: 9064917
    Abstract: A container for storing semiconductor devices is revealed. The container includes a receiving body, a seal plate, and a cover. At least one fastener and at least one driver are mounted in the receiving body. The seal plate is fastened under the receiving body and against the driver so as to fix the driver on the receiving body. When the driver is rotated, the fastener is driven to move in the receiving body by the driver. At least one fixing part of the fastener is moved toward at least one fastening part of the cover. By the fixing part locked in the fastening part, the cover is fixed on the receiving body. Thus a force opposite to the rotating shaft will not be generated around a periphery of the driver. Therefore stability of the rotating driver is improved and the container is opened and closed smoothly.
