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 pneumatic arrow gun has a gun body, an arrow, a positioning sleeve, and a connecting wire. The arrow is for inserting into an air tube of the gun body. The positioning sleeve is temporarily mounted around the air tube, and the arrow is disposed through the positioning sleeve. The connecting wire connects the gun body to the positioning sleeve. Because the positioning sleeve is temporarily mounted around the air tube, the arrow slides forward relative to the positioning sleeve after triggering. When triggering the arrow, the connecting wire naturally dangles. When the arrow detaches from the air tube, the positioning sleeve located at a nock of the arrow due to the sliding of the arrow. Therefore, a rebound of the arrowhead is prevented. The safety and the shooting stability are ensured. Further, the arrow is easily retrieved by the connecting wire.

Therefore, the high-pressure air in the high-pressure air source is easily released by actuate the actuating unit without additional hand tools.
