Patent ID: 8378499

Claim:
A semiconductor device comprising: an active region including a first region, a first channel region and a second region that are arranged in line in a first direction, the first channel region being sandwiched between the first and second regions; a first word line elongated in a second direction to cross the first channel region of the active region, the second direction being different from the first direction; a bit line elongated in a third direction to cross the second region of the active region, the third direction being different from each of the first and second directions; a bit line contact intervening between the second region of the active region and the bit line to form an electrical contact therebetween; a first cell contact formed in contact with the first region of the active region; a first storage node contact formed in contact with a part of the first cell contact, a center of the first storage node contact being out of vertical alignment with a center of the first cell contact; a first storage node contact pad formed in contact with a part of the first storage node contact pad being out of vertical alignment with the center of the first storage node contact; and a first capacitor formed in contact with the first storage node contact pad, wherein the active region further includes a second channel region and a third region that are arranged in line in the first direction, the second channel region being sandwiched between the second and third regions, and the device further comprises: a second word line elongated in the second direction to cross the second channel region of the active region; a second cell contact formed in contact with the third region of the active region; a second storage node contact formed in contact with a part of the second cell contact, a center of the second storage node contact being out of vertical alignment with a center of the second cell contact; a second storage node contact pad formed in contact with a part of the second storage node contact; and a second capacitor formed in contact with the second storage node contact pad.
