Title: Vacuum suction device for semiconductor manufacturing equipment
Inventor: PARK SOON-JONG
IPC: B23Q3/08
Filed: 1998-07-10
Abstract: PROBLEM TO BE SOLVED: To prevent wrong recognition of identification of a vacuum state and the consequent damage of a wafer, a reticle, or the like by installing a digital vacuum sensor in a vacuum line for moving an object such as the wafer by a vacuum suction system. SOLUTION: In a vacuum suction device for a semiconductor manufacturing installation for vacuum-sucking an object such as a wafer 41 or a reticle by a soft placing part 40 to move the object for a specified semiconductor device manufacturing process, a digital vacuum sensor 44 is installed in a vacuum line 42 creating vacuum on the upper face of the soft placing part 40 with the soft placed object. The suction and release state of the object is therefore sensed by the internal pressure of the vacuum line 42. Mechanical adjustment is unnecessary for the digital vacuum sensor 44, so that there is no vacuum sensing malfunction.

Abstract: PURPOSE:To eliminate the occurrence of a scratch and a collision sound due to a collision and to surely draw a focus in the case of closing a focus control loop by preventing the drawing in the case when a relative speed is large and the drawing is impossible. CONSTITUTION:An output of a comparator 3 is changed at timing when a focus deviation signal becomes a prescribed value.

Abstract: PURPOSE: To treat a low concentration of NOx efficiently using a compact device by first, allowing a nitrogen oxide to flow into an adsorbent-filled layer until the former reaches a saturation amount, then desorbing ammonia and the nitrogen oxide by heating the adsorbent-filled layer after the inflow of ammonia at a specified number of moles to the nitrogen oxide, and guiding both ammonia and nitrogen oxide to a catalytic layer for reduction. CONSTITUTION: A three way cock 3 is closed for ammonia and opened for a gas containing NOx, and the gas containing NOx is guided to an ammonia-NOx adsorbent layer 4. Further, the gas is supplied to the layer 4 until it reaches an adsorption saturation point by monitoring the adsorption level continuously with the help of an NOx meter 9. Next, the three way cock 3 is closed for the gas containing NOx and opened for the ammonia, and the gas is guided into the ammonia-NOx adsorbent layer 4 until the ammonia is almost equal to the number of moles of the NOx whose adsorption reaches the saturation point. After that, the three way cock 7 is opened for a denitrification catalytic layer, and the ammonia-NOx adsorbent layer 4 is heated to desorb both NOx and ammonia.  In addition, these are guided to the denitrification catalytic layer 10 so that NOx is removed by decomposition under an ammonia selective reduction reaction. The desulfurication catalyst is such as already used widely for selective reduction using NH3 .
