    摘要: A system comprises at least one semiconductor fabrication process apparatus with a fan for providing a downflow. A sensor is disposed on or in a conduit that is fluidly coupled to the semiconductor fabrication process apparatus for releasing an exhaust fluid of a process. The sensor is capable of detecting a characteristic of the exhaust fluid flowing within the conduit and producing a signal indicating the characteristic. A processor is coupled to the sensor. A venting apparatus is coupled to the processor. The processor compares the characteristic of the exhaust fluid with at least one predetermined value to control the venting apparatus.

    摘要: An apparatus and method for a fast recovery rectifier structure. Specifically, the structure includes a substrate of a first dopant. A first epitaxial layer lightly doped with the first dopant is coupled to the substrate. A first metallization layer is coupled to the first epitaxial layer. A plurality of trenches is recessed into the first epitaxial layer, each of which is coupled to the metallization layer. The device also includes a plurality of wells each doped with a second dopant type, wherein each well is formed beneath and adjacent to a corresponding trench. A plurality of oxide layers is formed on walls and a bottom of a corresponding trench. A plurality of channel regions doped with the first dopant is formed within the first epitaxial layer between two corresponding wells. Each of the plurality of channel regions is more highly doped with the first dopant than the first epitaxial layer.

    摘要: A dual-tank etch method which is suitable for the stripping of a silicon nitride layer from a pad oxide layer provided on a substrate, and etching of the pad oxide layer to a desired target thickness, is disclosed. The method includes providing a first processing tank containing a silicon nitride-stripping chemical; stripping the silicon nitride layer from the pad oxide layer by placing the substrate in the first processing tank; providing a second processing tank containing an oxide-etching chemical; and etching the pad oxide layer to the desired target thickness by placing the substrate in the second processing tank. By carrying out the pad oxide-etching step and the silicon nitride-stripping step in separate processing tanks, accumulation of silicon oxide precipitates in the second processing tank is avoided.
