摘要:
A resin worm wheel is formed by injection molding and includes a first end and a second end. The worm wheel is adapted to be driven by a worm. The worm wheel further includes: an engaging portion including a plurality of teeth engageable with the worm and a tooth space formed between the neighboring teeth; a first non-engaging portion adjacent to the engaging portion at the first end of the worm wheel and not engaging with the worm; and a first cutout portion formed at the first non-engaging portion continuously from the tooth space, the first cutout portion extending axially.
摘要:
A method for monitoring plasma-induced damage to a substrate while being processed in a plasma CVD apparatus includes: measuring DC floating potential of the substrate using a detection electrode in contact with the substrate while the substrate is processed in the apparatus; and detecting abnormality as plasma-induced damage based on the measured DC floating potential.
