  • Publication number: 20240145301
    Abstract: Disclosed are a metal thin film precursor composition, a method of forming a thin film using the metal thin film precursor composition, and a semiconductor substrate fabricated using the method. The metal thin film precursor composition includes a metal thin film precursor compound and a growth regulator including a predetermined terminal group and structure. In a thin film deposition process, by using the metal thin film precursor composition, side reactions may be suppressed and thin film growth rate may be controlled appropriately. Since process by-products in a thin film are removed, even when the thin film is formed on a substrate having a complicated structure, step coverage and the thickness uniformity and resistivity characteristics of the thin film may be greatly improved. In addition, corrosion or deterioration may be prevented, and the crystallinity of the thin film may be improved, thereby improving the electrical properties of the thin film.

  • Publication number: 20240128296
    Abstract: The present application discloses a double-layer stacked CMOS image sensor, photo diode and transfer gate transistor of a pixel cell are formed on the first substrate sequentially along a longitudinal direction, and the other pixel transistors of the pixel cell are formed on the second substrate. The first substrate and the second substrate are packaged separately, and the second substrate is stacked on the top side of the first substrate instead of being in juxtaposition. Since the photo diode and the pixel transistors other than the transfer gate transistor of the pixel cell are located on two separate substrates respectively, the area of a photo diode region may be increased significantly, thereby greatly increasing full well capacitance of the image sensor and increasing a dynamic range, and reduce a dark current and image noise significantly, thereby improving the dark line noise and full well capacitance simultaneously.
