  • Patent number: 7694498
    Abstract: The present invention provides a gas filling apparatus and gas filling port thereof. The gas filling apparatus is connected with the air feed apparatus which is introduced the gas into the first inlet port of the semiconductor device or reticle storage apparatus. The gas filling apparatus includes a supporting base which is provided to hold the storage apparatus thereon, and at least one second inlet port which is disposed on the first inlet port of the storage apparatus so as to the gas is flowed into the storage apparatus through the second inlet port. The second inlet port includes a first base, a second base, a first elastic element, a fixing element, and a switch device. Both of the first base and second base have through holes, and opposite to each other. The first elastic element is used to maintain the airtight and is disposed on the second base and opposite to the first inlet port of the storage apparatus used to maintain the airtight.

  • Publication number: 20090194140
    Abstract: A semiconductor substrate cleaning and reticle cleaning apparatus, and more particularly, a cleaning apparatus used to remove contaminants from the surface of the semiconductor substrate and the reticle in the semiconductor process, is disclosed in the present invention. The cleaning apparatus comprises a working platform, a base unit, and an adjustable cleaning unit. The base unit is composed of two vertical baseboards in parallel to each other and each vertical baseboard has a bottom end and a top end. The bottom ends of two vertical baseboards are placed on the working platform. The adjustable cleaning unit is pivotally disposed on the top ends of two vertical baseboards, wherein the adjustable cleaning unit comprises at least a long slot for transmitting a fluid to a surface of a semiconductor substrate or a reticle.
