SEMICONDUCTOR STRUCTURE AND METHOD FOR PREPARING SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 17899684 titled 'SEMICONDUCTOR STRUCTURE AND METHOD FOR PREPARING SAME
Simplified Explanation
The patent application describes a semiconductor structure and a method for preparing it.
- The method involves providing a substrate with active areas arranged in an array and an isolation structure separating the active areas.
- Buried word line structures are formed on one side of the substrate, close to the first surface, and embedded into the active areas.
- Bit line structures are formed on the first surface of the substrate and electrically connected to the active areas.
- Capacitor structures are formed on the second surface of the substrate and connected to the active areas in a one-to-one correspondence.
Original Abstract Submitted
A semiconductor structure and a method for preparing the same are provided. The method for preparing a semiconductor includes: providing a substrate including Active Areas (AAs) arranged in an array and an isolation structure separating the AAs, the substrate being provided with a first surface and a second surface opposite to each other; forming buried word line structures located on a side, close to the first surface, of the substrate and embedded into the AAs; forming bit line structures located on the first surface of the substrate and electrically connected to the AAs; and forming capacitor structures located on the second surface of the substrate and connected to the AAs in one-to-one correspondence.
