Abstract: PURPOSE:To prevent the current consumption and delay time of the protective circuit from being increased by a method wherein the depth of first conductivity type high- concentration impurity diffused layers of at least one part of a protective circuit is formed deeper than that of first conductivity type high-concentration impurity diffused layers other than the protective circuit, and a parasitic bipolar transistor with reduced breakdown strength is used in the protective circuit. CONSTITUTION:At least one part of a protective circuit is masked with a photoresist 206 and arsenic is ion-implanted to form high-concentration N-type impurity diffused layers 207 of a depth of 100 to 200nm or thereabouts. Then, phosphorus is ion-implanted in a state that the part of the protective circuit excluding at least the one part of the protective circuit is masked with a photoresist 208 to form high-concentration N-type impurity diffused layers 209 of a depth of 200 to 400nm or thereabouts. By deepening the junction of a parasitic bipolar transistor formed in one part of the circuit, the opposed areas of an emitter and a collector are widely extended in the lateral direction, the distance between the emitter and the collector is made short, a base width is made small and the breakdown strength of the transistor can be made low.

Filed: 1994-03-03
Abstract: PURPOSE: To provide the method for determining the word sequence of the specified vocabulary of a speech signal which conducts a little danger of the loss of a correct sequence of words during comparison while keeping search effort still relatively a little. CONSTITUTION: The speech signal is recognized until the output of a recognized word sequence or recognized sentence is divided. Only word hypotheses are generated individually at different start moments, and preliminary word strings are formed from the individual word hypotheses according to a word graph, which is continuously optimized by erasing the part of the word string. For the purpose, parts of word strings having the same start point and end point are compared with each other and the score of a word having a cycling end point is compared with a threshold value. Postediting operation is introduced as the optimization step of the word graph. In this case, other words having the same start are all outputted for wrong words and an operator speedily selects a correct word out of all other words.
