摘要： A method for fabricating a MOS transistor having an offset resistance in a channel region controlled by a gate voltage and structure thereof is disclosed. A gate electrode is divided into three adjacent regions of respectively a second conductivity type, first conductivity type and second conductivity type connected laterally to one another on a channel region. A gate control voltage is applied to a central region of the first conductivity type, and a predetermined voltage between maximum and minimum values of the gate control voltage is applied to left and right adjacent regions of the second conductivity type. If a gate turn-on voltage is applied to the central region the gate turn-on voltage is forward biased to the adjacent left and right regions and is therefore also applied to the forwardly biased left and right regions. The effective length of the gate electrode then becomes the total length of the central region and the left and right adjacent regions. If a gate turn-off voltage is applied to the central region the central region becomes reverse biased with the left and right adjacent regions and thus the effective length of the gate electrode becomes the length of only the central region of the first conductivity type. This reduces the length of the channel region, and thus forms an offset resistance structure which reduces leakage current in the off state of the MOS transistor.

摘要翻译： 公开了一种制造具有由栅极电压控制的沟道区域中的偏移电阻的MOS晶体管及其结构的方法。 栅极电极被分成在沟道区域上彼此侧向连接的第二导电类型，第一导电类型和第二导电类型的三个相邻区域。 栅极控制电压施加到第一导电类型的中心区域，栅极控制电压的最大值和最小值之间的预定电压被施加到第二导电类型的左右相邻区域。 如果栅极导通电压施加到中心区域，则栅极导通电压被正向偏置到相邻的左右区域，并且因此也被施加到向前偏置的左右区域。 然后，栅电极的有效长度变为中心区域和左右相邻区域的总长度。 如果向中心区域施加栅极截止电压，则中心区域与左右相邻区域反向偏置，因此栅电极的有效长度仅成为第一导电类型的中心区域的长度。 这减小了沟道区的长度，从而形成了减小MOS晶体管的截止状态下的漏电流的偏移电阻结构。
