Title: Semiconductor device, its manufacture and differential amplifier device
Inventor: TAKEUCHI KIYOSHI
IPC: H01L27/088
Filed: 1997-11-12
Abstract: PROBLEM TO BE SOLVED: To reduce input offset voltage and to highly precisely detect matching of a micro potential difference, by setting sum of first and second area thickness to be smaller than the thickness of a source or drain area, and setting an impurity concentration of the second area to be higher than that of the first area. SOLUTION: When appropriate voltage is applied to a source drain and a gate terminal, a depletion layer is formed in a substrate of an inversion layer 7 formed on a surface of a channel of a semiconductor area, which is immediately below a gate electrode 3 and whose both sides are sandwiched by source drain diffused layers 4 and 5. Since the concentration in the first region near a substrate surface is low in the range of WDEP from the surface by depth in the depletion layer, threshold fluctuations are reduced. But, the concentration in the second region part is high in the range of WDEP, the extension of the depletion layer in a lateral direction from the source drain is suppressed and short channel effect is improved.  Consequently, impurity concentration is distributed to be low on a surface side and high on an inner side and short channel effect is not deteriorated, a threshold is not changed, and only the threshold fluctuations are reduced.
