20140035055 | SEMICONDUCTOR INTEGRATED CIRCUIT DEVICE AND METHOD FOR MANUFACTURING SEMICONDUCTOR INTEGRATED CIRCUIT DEVICE - MISFETs after the 32 nm technology node have a High-k gate insulating film and a metal gate electrode. Such MISFETs have the problem that the absolute value of the threshold voltage of n-MISFET and p-MISFET inevitably increases by the subsequent high temperature heat treatment. The threshold voltage is therefore controlled by forming various threshold voltage adjusting metal films on a High-k gate insulating film and introducing a film component from them into the High-k gate insulating film. The present inventors have however revealed that lanthanum or the like introduced into the High-k gate insulating film of the n-MISFET is likely to transfer to the STI region by the subsequent heat treatment. | 02-06-2014 |

In a method for manufacturing a semiconductor device, a metal film is formed over a semiconductor substrate having an insulating film formed on a surface thereof, and then the metal film is removed in a memory cell region, whereas, in a part of a peripheral circuit region, the metal film is left. Next, a silicon film is formed over the semiconductor substrate, then the silicon film is patterned in the memory cell region, and, in the peripheral circuit region, the silicon film is left so that an outer peripheral portion of the remaining metal film is covered with the silicon film. Subsequently, in the peripheral circuit region, the silicon film, the metal film, and the insulating film are patterned for forming an insulating film portion formed of the insulating film, a metal film portion formed of the metal film, and a conductive film portion formed of the silicon film. | 08-28-2014 |
