  • Publication number: 20240136175
    Abstract: The present invention relates to an auxiliary precursor, a thin film precursor composition, a method of forming a thin film using the thin film precursor composition, and a semiconductor substrate fabricated using the method. The present invention provides the thin film precursor composition including a thin film precursor compound and a compound having a predetermined structure that exhibits reaction stability as the auxiliary precursor. By using the thin film precursor composition in a thin film deposition process, side reactions may be suppressed, and thin film growth rate may be appropriately controlled. In addition, since process by-products are removed from a thin film, even when a 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.

  • Patent number: 11913114
    Abstract: A semiconductor manufacturing apparatus including a process chamber and a boat having a support member supporting substrates arranged in a first direction. An inner tube encloses the boat and includes a slit along a side wall. A nozzle supplies a process gas and includes a gas injection port at a position corresponding to the slit. The gas injection port includes a first inlet and first outlet. The slit includes a second inlet and second outlet. A distance to an end of the first inlet from a center line that connects a center of the first inlet and a center of the second outlet is different from the distance from the center line to an end of the first outlet and/or a distance from the center line to an end of the second inlet is different from a distance from the center line to an end of the second outlet.

  • Patent number: 9427496
    Abstract: An artificial tissue including an internal mass transport network having a plurality of channels, wherein the channels are designed to substantially mimic naturally occurring vascular network and a method for creating an internal transport system within a tissue scaffold to improve circulation, diffusion, and mass transport properties by utilizing computer-aided tissue engineering (CATE). The artificial tissue has the internal mass transport network of channels embedded, deposited, or molded within a scaffold, wherein the channels are made from a biodegradable transporting material and the scaffold is made from a scaffold material. The artificial tissue of the invention includes a basic circulatory system embedded within the tissue scaffold. This system provides mass transport throughout the entire scaffold and degrades after the new circulatory system develops.
