Patent 8432016 was granted and assigned to RF Micro Devices on April, 2013 by the United States Patent and Trademark Office.
The present disclosure relates to a stacked body-contacted field effect transistor (FET) that includes multiple body-contacted FETs coupled in series and a lateral isolation band encircling a periphery of the multiple FETs. The multiple FETs include a first end FET having a first body, which is not directly connected to any body of any other of the multiple FETs, and a second end FET having a second body, which is not directly connected to any body of any other of the multiple FETs. The multiple FETs may include inner FETs that incorporate merged source-drains to save space. By keeping the bodies electrically separated from one another, the full benefits of body-contacting may be realized. However, by incorporating multiple FETs within a single lateral isolation band further saves space.
