Abstract: A method and apparatus for measuring the vacuum gripping strength of a vacuum wand or robotic arm provides a pressure gauge and a conduit extending from the pressure gauge and terminating at an opening formed in a receiving surface. A vacuum wand head is positioned on the receiving surface such that the gripping surface of the vacuum wand forms a conterminous boundary with the receiving surface and the vacuum port of the vacuum wand is aligned over the opening formed in the receiving surface. The receiving surface replicates a wafer surface so that the same vacuum gripping strength as would be delivered to a wafer being gripped by the vacuum wand, is thereby sensed by the pressure gauge. Spring loaded positioning members act in conjunction with a clamp member and a mechanical stop position the vacuum wand head in the receiving area and over the opening and also to assure that the gripping surface of the vacuum wand head is flush against the surface of the receiving area.

Abstract: A method of forming very small silicon nitride spacers in split-gate flash EPROMs is disclosed which prevent the occurrence of “write disturb”, unwanted reverse tunneling, or erasing. This is accomplished by forming spacers with well-controlled dimensions and well-defined shapes through a judicious use of a fully wet etch technique, including main-etch and over-etch. The use of a phosphoric acid solution in combination with sulfuric acid+hydrogen peroxide widens the process window from a few seconds to several minutes so that the small-dimensioned silicon nitride spacers can be better controlled than it has been possible in the past. In the first embodiment phosphoric solution is used both for main-etch and for over-etch. In the second embodiment, phosphoric solution is used for main-etch only, while the sulfuric+hydrogen peroxide solution is used as an over-etch in forming the tiny silicon nitride spacers of the invention.

Abstract: A mask for skin diving includes a skirt and two lenses laterally symmetrically mounted within the skirt. The skirt has two outer ends that are rearward inclined by a predetermined angle, and the lenses also have two outer ends that are rearward inclined by an angle corresponding to the skirt, so that a user's sight projecting toward two lateral sides could be widened without being blocked by the skirt. The angle by which the outer ends of the skirt and the lenses are rearward inclined is preferably within the range from 5 to 10 degrees.
