    摘要: A semiconductor device includes a second insulator layer (12) a first conductor layer (13) and a second insulator layer (14) stacked in this order on a semiconductor substrate (11), and a trench (15) formed to penetrate the stacked triple layer and extend into the semiconductor substrate. A capacitor is formed at a portion of the trench located in the semiconductor substrate. A transistor is formed directly on this capacitor. The capacitor has one electrode formed of the semiconductor substrate and the other electrode formed of a second conductor layer (18) formed in the trench to open a dielectric film (17). The transistor includes a gate electrode formed of the first conductor layer and source/drain regions (20, 21) of a second conductivity type distributed in the vicinity of the first and second insulator layers in an active layer (19) filling the trench. The drain and source regions of the transistor are formed by thermally diffusing impurities included in the first and second insulator layers into the active layer. Since a region to be added only for isolation is unnecessary in this semiconductor device and a manufacture method thereof, a memory cell area can be reduced, resulting in higher integration of the device.

    摘要: A vacuum-treatment apparatus employs a magnetically driven clamp which uses repulsive and attractive forces between magnets. The clamp mechanism is simplified, maintenance of the apparatus can be easily performed, and the surfaces which mechanically contact one another are decreased as much as possible so that a vacuum-treatment apparatus which generates less dust is obtained.

    摘要: A wafer treating device utilizing a plasma generated by a gas discharge caused by electron cyclotron resonance (ECR) includes a wafer treating chamber and a plasma generating chamber, a microwave supply for supplying microwave energy to the plasma generating chamber, and an electromagnetic coil which surrounds the plasma generating chamber to produce a minimum B-field therein. A plasma generated in the plasma generating chamber by electron cyclotron resonance is confined stably therein by the minimum B-field produced by the coil. Thus, the density and stability of the plasma in the plasma generating chamber are enhanced. The plasma in the plasma generating chamber is conveyed to a wafer in the wafer treating chamber along the diverging lines of a magnetic force. Examples of the minimum B-field producing coil include Ioffe bars, a baseball coil and an Yin-yang coil.

    摘要: A method of cleaning semiconductor devices which removes or transmutes the contaminants sticking on sidewalls of a pattern or a trench is formed is disclosed. A substrate to be treated on which a pattern or a trench is formed is located in a processing container. A reactive gas which reacts with the contaminants sticking on the sidewall of the pattern or the trench to produce reactive ions which remove or transmute the contaminants is introduced into the processing container. Plasma of the reactive gas is produced by electronic cyclotron resonance in order to produce reactive ions from the reactive gas introduced into the processing container. According to the method, the temperature of the reactive ions in the plasma becomes high, with the result that the motion of the reactive ions in the plasma becomes more active. Accordingly, a velocity vector in a horizontal direction of the reactive ions becomes larger, which enables efficient removal or change in quality of the contaminants sticking on the sidewalls of the pattern or the trench.
