A method for etching a bevel edge of a substrate in a processing chamber is provided. The method includes flowing an inert gas into a center region of the processing chamber defined above a center region of the substrate and flowing a mixture of an inert gas and a processing gas over an edge region of the substrate. The method further includes striking a plasma in the edge region, wherein the flow of the inert gas and the flow of the mixture maintain a mass fraction of the processing gas substantially constant. A processing chamber configured to clean a bevel edge of a substrate is also provided.

A joint assembly is mounted between adjacent supports of a frame of a tent and has a female joint, a male joint and a slide. The male joint covers on the female joint. The slide is mounted slidably between the joints and abuts a resilient member. The female joint has a partition with at least one through hole to allow a protrusion of the slide to selectively pass through. When the slide moves to mount the protrusion in the through hole, the joints are held from rotating relative to each other. When the slide moves to completely retract between the joints, the protrusion leaves the through hole to allow the joints to rotate relative to each other. Therefore, when the frame is folded, the slide is completely retracted to avoid damage other components.

A fan resistor is formed with a resistive pattern of electrically conductive material sandwiched between two panels of thermally conductive material. An insulating barrier on each surface of the resistive pattern electrically insulates it from the thermally conductive panels. The resistive pattern is cut from a sheet of metal using a stamping machine and the cut resistive pattern is dropped on one of the panels, a surface of which has an electrically insulating barrier thereon.

A foldable car cover tent having an opening comprises a base that has a first lateral plate parallel to a second lateral plate. The front and rear ends of the base are respectively connected to a front support set and a rear support set. A cover is provided for covering the front and rear support sets. The rear support set includes a first movable support and a second movable support, both of which have two sides pivotally connected to the first and second lateral plates respectively A rope is also provided. One end of the rope connects to the first movable support while another end passes through the second movable support. Thereby, the first and second movable supports together with the cover can be pulled simultaneously when the rope is pulled, and then an opening is formed for cars entering or exiting.

A method for making an inference based on cumulative data. The method utilizes video, audio, and biometric devices to observe a retail environment for the presence of a customer. Once a customer is present, the method identifies every cohort to which the customer corresponds. Next, the method observes the customer as they peruse aisles in the retail environment. When the customer selects a product, the method identifies the selected product and searches the cohorts for alternate products to offer the customer. The method offers one alternate product to the customer and records to the cohorts whether the customer thereinafter accepts the method's offer and selects the alternate product or rejects the method's offer and continues perusing the retail environment aisles. The method continues observing the customer and offering alternate product until the customer leaves the retail environment.

Methods and systems to optimize wafer placement repeatability in semiconductor manufacturing equipment using a controlled series of wafer movements are provided. In one embodiment, a preliminary station calibration is performed to teach a robot position for each station interfaced to facets of a vacuum transfer module used in semiconductor manufacturing. The method also calibrates the system to obtain compensation parameters that take into account the station where the wafer is to be placed, position of sensors in each facet, and offsets derived from performing extend and retract operations of a robot arm. In another embodiment where the robot includes two arms, the method calibrates the system to compensate for differences derived from using one arm or the other. During manufacturing, the wafers are placed in the different stations using the compensation parameters.
