Abstract: A semiconductor device includes a first transistor and a first gate electrically coupled to the first transistor. A second transistor is positioned on top of the first transistor. A second gate is electrically coupled to the second transistor. A dielectric isolation layer is positioned between the first gate and the second gate. A first conductive contact is electrically coupled to the first gate. A second conductive contact is electrically coupled to the second gate. A control of the first gate through the first conductive contact is independent of a control of the second gate through the second conductive contact.

Abstract: Embodiments of the present invention are directed to monolithic stacked field effect transistor (SFET) processing methods and resulting structures having dual middle dielectric isolation (MDI) separation. In a non-limiting embodiment of the invention, a first nanosheet is formed and a second nanosheet is vertically stacked over the first nanosheet. A gate is formed around a channel region of the first nanosheet and a channel region of the second nanosheet and a middle dielectric isolation structure is formed between the first nanosheet and the second nanosheet. The middle dielectric isolation structure includes a first middle dielectric isolation layer and a second middle dielectric isolation layer vertically stacked over the first middle dielectric isolation layer. A portion of the gate extends between the first middle dielectric isolation layer and the second middle dielectric isolation layer in the middle dielectric isolation structure.

Abstract: The present disclosure relates to electromagnetic shielding paper based on modification of a conductive MOF material and a preparation method thereof, and belongs to the technical field of electromagnetic shielding. The method includes the following steps: putting polyimide fibers into a precursor solution of the conductive MOF material, and reacting to obtain MOF material modified PI fibers; mixing the modified fibers with aramid pulp, and carrying out papermaking, squeezing and drying to obtain a paper-based precursor; generating a conductive polymer (polypyrrole) in situ by using a gas-phase polymerization method, and finally obtaining the electromagnetic shielding paper based on the modification of the conductive MOF material. The electromagnetic shielding paper prepared by the present disclosure not only has good conductivity and electromagnetic shielding performance, but also has good mechanical properties and thermal stability.

In the present disclosure, PI fibers are modified by polydopamine and grafted with carbon nanotubes, polyimide fiber paper is prepared by a wet papermaking technology, an in-situ synthesis method is used to enable conductive MOFs and polymer PPy to grow on the fiber paper, and finally polyimide resin is sprayed onto the paper to prepare the paper-based electromagnetic shielding composite with flame retardant properties. The method is simple in process without complex synthesis equipment, and solves the problems that polyimide fiber paper is poor in paper forming property and paper mechanical property, and carbon nanotubes are easy to agglomerate in paper and limited in addition amount in the prior art.
