Title: Semiconductor device and fabrication method thereof
Inventor: TOMITA HIROYOSHI
IPC: H01L27/108
Filed: 2007-04-27
Abstract: A semiconductor device and a fabricating method thereof are provided to suppress the generation of a restore failure and off leak current failure even if a threshold of a MOSFET disperses as the miniaturization of element structure and the decrease of drive voltage advance. The maximum field strength to be applied to a gate oxide film is determined by a potential difference between a word line(104) and source-drain regions(108,109). The potential of the word line and the potential of the source-drain regions are determined by a power supply (or potential of the capacitor(103)) connected to each other, regardless of a back bias potential(V_BB). Even if the back bias potential set shallow, the field strength to be applied to the gate oxide film does not change, so that dielectric breakdown of the gate oxide film does not easily occur. A threshold of a cell transistor is estimated for each DRAM chip, and the back bias potential is set shallower than a design value only if the estimated value is high.
