摘要:
The upper electrode of a capacitor is constituted of laminated films which act to prevent hydrogen atoms from reaching the capacitor electrodes and degrading performance. In one example, a four layer upper electrode respectively acts as a Schottky barrier layer, a hydrogen diffusion preventing layer, a reaction preventing layer, and an adsorption inhibiting layer. Therefore, the occurrence of a capacitance drop, imperfect insulation, and electrode peeling in the semiconductor device due to a reducing atmosphere can be prevented. In addition, the long-term reliability of the device can be improved.

摘要:
A microcassette tape comprising a tape housing including top and bottom case halves, a reel, a tape mounted on said reel, a rotating shaft for the tape reel, a pinch roller provided at the front of the tape housing, and a capstan between which the tape passes during endless revolutions of the tape. A guide is provided for preventing the tape from being misdirected and caught around the pinch roller and a wall is provided as a part of the tape housing for preventing the tape from slackening as it passes between the pinch roller and the capstan on a tangential path to the guide member which prevents the tape from being caught by the pinch roller. A further guide element is provided which prevents the tape from falling off the tape reel. A hole is provided in one of the halves of the tape housing which permits insertion of a shaft member for taking up any tape slack which develops in the passage of the tape from the tape reel to the pinch roller.
