Stacked carbon-based FETs |
摘要 |
Methods and systems for forming stacked transistors. Such methods include forming a lower channel layer on a substrate; forming a pair of vertically aligned gate regions over the lower channel layer; forming a pair of vertically aligned source regions and a pair of vertically aligned drain regions on the lower channel material, each pair separated by an insulator; forming an upper channel material over the source regions, drain regions, and gate regions; and providing electrical access to the source, drain, and gate regions. |

1. A method for forming stacked transistors, comprising:
forming a lower channel layer on a substrate; forming a pair of vertically aligned gate regions over the lower channel layer; forming a pair of vertically aligned source regions and a pair of vertically aligned drain regions on the lower channel material, each pair separated by an insulator; forming an upper gate dielectric over the source regions, drain regions, and gate regions; forming an upper channel material over the upper gate dielectric; and providing electrical access to the source, drain, and gate regions. |
