Patent number: 7414293Abstract: A semiconductor device has an n channel conductivity type field effect transistor having a channel formation region formed in a first region on one main surface of a semiconductor substrate and a p channel conductivity type field effect transistor having a channel formation region formed in a second region on the main surface of the semiconductor substrate, which second region is different from the first region. An internal stress generated in the channel formation region of the n channel conductivity type field effect transistor is different from an internal stress generated in the channel formation region of the p channel conductivity type field effect transistor. The internal stress generated in the channel formation region of the n channel conductivity type field effect transistor is a tensile stress, while the internal stress generated in the channel formation region of the p channel conductivity type field effect transistor is a compressive stress.Type: GrantFiled: October 3, 2006Date of Patent: August 19, 2008Assignee: Renesas Technology Corp.Inventors: Akihiro Shimizu, Nagatoshi Ooki, Yusuke Nonaka, Katsuhiko Ichinose

Patent number: 7414294Abstract: A plurality of quantum dots each have a shell. The quantum dots are embedded in an organic matrix. At least the quantum dots and the organic matrix are photoconductive semiconductors. The shell of each quantum dot is arranged as a tunneling barrier to require a charge carrier (an electron or a hole) at a base of the tunneling barrier in the organic matrix to perform quantum mechanical tunneling to reach the respective quantum dot. A first quantum state in each quantum dot is between a lowest unoccupied molecular orbital (LUMO) and a highest occupied molecular orbital (HOMO) of the organic matrix. Wave functions of the first quantum state of the plurality of quantum dots may overlap to form an intermediate band.Type: GrantFiled: December 16, 2005Date of Patent: August 19, 2008Assignee: The Trustees of Princeton UniversityInventor: Stephen R.

Patent number: 7414297Abstract: The invention includes methods of forming rugged electrically conductive surfaces. In one method, a layer is formed across a substrate and subsequently at least partially dissociated to form gaps extending to the substrate. An electrically conductive surface is formed to extend across the at least partially dissociated layer and within the gaps. The electrically conductive surface has a rugged topography imparted by the at least partially dissociated layer and the gaps. The topographically rugged surface can be incorporated into capacitor constructions. The capacitor constructions can be incorporated into DRAM cells, and such DRAM cells can be incorporated into electrical systems.Type: GrantFiled: September 21, 2007Date of Patent: August 19, 2008Assignee: Micron Technology, Inc.Inventors: Marsela Pontoh, Cem Basceri, Thomas M.
