Abstract: An ammonium fluoride gas may be used to form a protection layer for one or more interlayer dielectric layers, one or more insulating caps, and/or one or more source/drain regions of a semiconductor device during a pre-clean etch process. The protection layer can be formed through an oversupply of nitrogen trifluoride during the pre-clean etch process. The oversupply of nitrogen trifluoride causes an increased formation of ammonium fluoride, which coats the interlayer dielectric layer(s), the insulating cap(s), and/or the source/drain region(s) with a thick protection layer. The protection layer protects the interlayer dielectric layer(s), the insulating cap(s), and/or the source/drain region(s) during the pre-clean process from being etched by fluorine ions formed during the pre-clean process.

Abstract: A bag for storing tennis balls has an hermetic enclosure formed of flexible material, an opening larger than a tennis ball into the enclosure, the opening having a hermetic sealing zipper by which the opening may be opened and closed, and a flexible tubing from outside the enclosure through the flexible material, the flexible tubing having an open end adapted to engage an air pump, and a one-way valve adapted to admit air into the enclosure and to prevent air from exiting the enclosure through the tubing. Tennis balls placed into the bag are placed under pressure higher than the pressure inside a tennis ball by closing the opening by closing the hermetic sealing zipper, engaging an air pump to the open end of the flexible tubing, and operating the air pump until a predetermined pressure is established in the bag.

Abstract: The invention discloses an X-type adjustment module, comprising a cover, a first frame, a second frame, a first light transmitting element, a second light transmitting element, a first adjustment member, and a second adjustment member. The first frame is pivotally connected to the cover. The second frame is pivotally connected to the first frame and intersects the first frame. The first light transmitting element is fixed in the first frame. The second light transmitting element is fixed in the second frame and intersects the first light transmitting element. The first adjustment member passes through the cover and abuts against the first frame. The second adjustment member passes through the cover and abuts against the second frame. A transmission path of a light beam is controlled by adjusting disposition angles of the first light transmitting element and the second light transmitting element to avoid excessive concentration of light energy.

Abstract: An optical mechanism includes a substrate, a supporting pad, an optical element and a fixed member. The substrate has an opening and a recess, the recess surrounds the opening and has a bottom surface. The supporting pad is disposed in the recess and has a convex curved portion, the convex curved portion protrudes away from the bottom surface of the recess, and a gap exists between the convex curved portion and the bottom surface. The optical element is disposed on the substrate, and the optical element covers the opening and abuts against the convex curved portion. The fixed member is fixed on the substrate and is adapted to press the optical element onto the substrate. The optical mechanism and the projection device of the invention can effectively prevent the optical element from being broken.
