Abstract: A semiconductor device having an improved negative bias temperature instability lifetime characteristic is manufactured by forming a first insulating layer on a substrate, performing a first nitridation on the first insulating layer to form a second insulating layer, and sequentially performing a first and second anneal on the second insulating layer to form a third insulating layer, wherein the second anneal is performed at a higher temperature and with a different gas than the first anneal. A second nitridation is performed on the third insulating layer to form a fourth insulating layer, and a sequential third and fourth anneal on the fourth insulating layer forms a fifth insulating layer. The third anneal is performed at a higher temperature than the first anneal, and the fourth anneal is performed at a higher temperature than the second anneal and with a different gas than the third anneal.

Abstract: Disclosed herein is a method of processing rounded toothbrush bristles using synthetic bristles. The method includes cutting one end of a filament bundle of synthetic bristles, mechanically polishing the cut end of the filament bundle of synthetic bristles, heat treating the polished end of the filament bundle of synthetic bristles, and caustisizing the heat-treated end of the filament bundle of synthetic bristles into a round shape. In this method, at least one end of the toothbrush bristle is softly rounded to protect gum damage due to irritation of the one end of the toothbrush bristle and to provide a gum massaging effect for healthy gum with the rounded end of the toothbrush bristle.

Abstract: A radio dispatch system has a plurality of base stations covering a large geographic area. The base stations are connected to the Internet so voice messages can be sent between them. Each of a plurality of mobile transceivers is adapted to send voice messages to one of the base stations and receive voice messages from one of the base stations. As a result, the mobile transceivers can communicate with each other and the base stations over a wide geographic area limited only by the reach of the Internet.
