| Number | Title | Issue Date |
| 7368317 | Method of producing an N-type diamond with high electrical conductivity The invention relates to a method of producing an n-type diamond. The inventive method comprises an n-doping stage during which a donor species is vacuum diffused in a diamond that was initially doped with an acceptor, in order to form donor groups containing the do... | 05/06/2008 |
| 7329583 | Method of fabricating isolated semiconductor devices in epi-less substrate An structure for electrically isolating a semiconductor device is formed by implanting dopant into a semiconductor substrate that does not include an epitaxial layer. Following the implant the structure is exposed to a very limited thermal budget so that dopant does... | 02/12/2008 |
| 7276794 | Junction-isolated vias A process for forming a junction-isolated, electrically conductive via in a silicon substrate and a conductive apparatus to carry electrical signal from one side of a silicon wafer to the other side are provided. The conductive via is junction-isolated from the bulk... | 10/02/2007 |
| 7144795 | Method for forming a depletion-mode transistor that eliminates the need to separately set the threshold voltage of the depletion-mode transistor A semiconductor circuit with a depletion-mode transistor is formed with a method that eliminates the need for a separate mask and implant step to set the threshold voltage of the depletion-mode transistor. As a result, the method of the present invention reduces the... | 12/05/2006 |
| 6110276 | Method for making n-type semiconductor diamond A method for making n-type semiconducting diamond by use of CVD in which n-type impurities are doped simultaneously with the deposition of diamond. As the n-type impurities, an Li compound and a B compound, both, are used at once. After doping, a diamond ... | 08/29/2000 |
| 5514603 | Manufacturing method for diamond semiconductor device A process of forming a semiconductor which allows n type doping to be applied to a diamond semiconductor layer is carried out so as to form a diamond semiconductor layer on a substrate, forming a layer of SiO2 over the diamond semiconductor lay... | 05/07/1996 |
| 5508208 | Method of manufacturing diamond semiconductor In a method of manufacturing diamond semiconductor mainly composed of carbon, a technique is provided which is free from the possibility of destruction of diamond structure, permits n-type doping into diamond and further permits high concentration n-type ... | 04/16/1996 |
