    • A technique for improving characteristics of a semiconductor device (DMOSFET) is provided. A semiconductor device is configured so as to include: an n-type source layer (102) disposed on an upper portion of a first surface side of an SiC substrate (106); a p body layer (103) which surrounds the source layer and has a channel region; an n−-type drift layer (107) which is in contact with the p body layer (103); a gate electrode (116) which is disposed on an upper portion of the channel region via a gate insulating film; and a first p+ layer (109) which is disposed in the p body layer (103), extends to a portion below the n+ source layer (102), and serves as a buried semiconductor region having an impurity concentration higher than that of the p body layer (103). In this manner, since the first p+ layer (109) is formed in the middle of the p body layer (103), it is possible to reduce the diffusion resistance of the p body layer (103). Thus, it is possible to make a parasitic bipolar transistor harder to turn on.
    • 提供了一种用于改善半导体器件(DMOSFET)的特性的技术。 半导体器件被配置为包括:设置在SiC衬底(106)的第一表面侧的上部的n型源极层(102); 围绕源层并具有沟道区的p体层(103); 与p体层(103)接触的n型漂移层(107); 栅极电极,其经由栅极绝缘膜设置在所述沟道区域的上部; 并且设置在p体层(103)中的第一p +层(109)延伸到n +源极层(102)下方的部分,并且用作具有高于p的杂质浓度的掩埋半导体区域 身体层(103)。 以这种方式,由于第一p +层(109)形成在p体层(103)的中间,所以可以降低p体层(103)的扩散阻力。 因此,可以使寄生双极晶体管更难以导通。

    • An analyzing apparatus includes a microchip, a detecting unit and an analyzing-measuring unit. The microchip is formed of a light transmissive material formed with a separation fluid channel that is a light measuring part. The detecting unit includes an emitted-light guiding unit that emits light to the separation fluid channel, and a received-light guiding unit that receives light through the separation fluid channel. The emitted-light guiding unit or the received-light guiding unit placed at a position facing a microchip support table via the microchip abuts the microchip, and pushes the microchip in a direction toward the microchip support table. The analyzing-measuring unit includes the detecting unit, the emitted-light guiding unit and the received-light guiding unit, and detects a constituent of a sample filled in the separation fluid channel.
