Silicon sol (size of 20nm) is softer than Al/sub 2/O/sub 3/, has no contamination, and better dispersity and suspension with little scratching. Moreover, adding non-metal ions to the chelate can compress contamination of metal ions and adsorption of particles, so that the surface is smooth and bright.","PeriodicalId":349087,"journal":{"name":"2001 6th International Conference on Solid-State and Integrated Circuit Technology.

This paper proposes a recursive training algorithm to alleviate the difficulty, and improves the training procedure highly automatic. The result model is a multi-resolution combined classifier (MRCC). Experiments are made following some recent evaluation criteria known in literature, and show that compared with the original model, the MRCC has better classification performance, better adaptive learning ability and consume less computation resource.","PeriodicalId":349087,"journal":{"name":"2001 6th International Conference on Solid-State and Integrated Circuit Technology.

The protrusions were fabricated by our original self-organized selective oxidation technique, referred to as \"nano-LOCOS\". Although the Si protrusions were quite small, high emission current was detected at low anode voltages, depending on the microscopic shape controlled by oxidation conditions.
