  • Publication number: 20240154015
    Abstract: A method includes forming a first fin and a second fin protruding from a frontside of a substrate, forming a gate stack over the first and second fins, forming a dielectric feature dividing the gate stack into a first segment engaging the first fin and a second segment engaging the second fin, and growing a first epitaxial feature on the first fin and a second epitaxial feature on the second fin. The dielectric feature is disposed between the first and second epitaxial features. The method also includes performing an etching process on a backside of the substrate to form a backside trench, and forming a backside via in the backside trench. The backside trench exposes the dielectric feature and the first and second epitaxial features. The backside via straddles the dielectric feature and is in electrical connection with the first and second epitaxial features.

  • Publication number: 20110166804
    Abstract: For example, to adjust an offset of a pressure sensor, there are provided an external resistor RE and an internal resistor circuit that is connected to both ends of RE and formed in a semiconductor chip such as a processor. The internal resistor circuit includes N pieces of internal resistors RI connected in series between both ends of RE, and (N+1) pieces of switches selecting one of voltages of respective nodes of the serial resistors and outputs the same as a signal. RE has a high absolute value precision of, e.g., several ten ohms to several hundred ohms, and RI has a high relative value precision of, e.g., several kilo-ohms. Therefore, an offset adjustment range is decided at a high absolute value precision mainly by RE, and with regard to the arrangement resolution, a high precision can be obtained along with the relative value precision of the RI.
