    摘要: Disclosed is an LDDMOSFET, in which a gate electrode (2) having a cross-sectional shape having a lower side and an upper side longer than the upper side is formed of only conductive materials, and diffusion layers (5b, 6b) of low concentration and high concentration constituting a drain are both formed so as to be overlapped with portions below the gate electrode (2) utilizing the shape of this gate electrode (2). Since the gate electrode (2) is formed of only the conductive materials, it becomes easy to word the gate electrode (2) so as to be in a desired shape. Since the diffusion layers (5b, 6b) of low concentration and high concentration constituting the drain are both overlapped with the portions below the gate electrode (2), the performance as a transistor is not degraded even if the polarity of the surface of the diffusion layer (5b, 6b) of low concentration is inverted by the effect of hot electrons.

    摘要: In a content addressable memory (CAM) cell according to the present invention, a pair of non-volatile memory transistors hold data, whereby stored data will not disappear even if power is cut. Conducting terminals of these non-volatile transistors are connected to a bit line pair, so that the stored data can be directly read out from the bit line pair. Further, the invention CAM system converts the value of a current flowing in a match line into a voltage value to perform content reference, and hence the same can be employed as an associative memory system.

    摘要: The invention provides a method for manufacturing a large scale quartz glass slab ingot in a flame hydrolysis reaction in a furnace, including the steps of rotating the furnace, depositing a fused silica on a furnace bed, and extending the deposit outwardly by heating and rotation of the furnace, thereby a quartz glass slab ingot is obtained. A quartz glass burner is installed at the ceiling of the furnace, hydrogen gas supplied to the burner flows down along the tapered wall of the oxygen chamber and is ejected into the outer casing. Part of the hydrogen gas is deflected to the center of the burner and mixed with the oxygen just after the ejection from the oxygen gas nozzles. Thereby, the flame is formed smoothly and the thermal efficiency is improved. The flame becomes wide enough and the silica powder transported by the hydrogen gas is uniformly fused by the flame and heat capacity of the fused silica.
