  • Patent number: 7867924
    Abstract: A method of fabricating a semiconductor device includes forming a lower device on a lower semiconductor substrate, and forming an interlayer insulating film on the lower device. An upper semiconductor substrate is formed on the interlayer insulating film such that the interlayer insulating film is between the lower and upper semiconductor substrates. Upper trenches are formed within the upper semiconductor substrate. An upper device isolating film is formed within the upper trenches. The upper device isolating film is irradiated with ultraviolet light having a wavelength configured to break chemical bonds of impurities in the upper device isolating film to reduce an impurity concentration thereof.

  • Patent number: 7605022
    Abstract: A method of fabricating a three-dimensional semiconductor device is provided along with a three-dimensional semiconductor device fabricated thereby. The method includes forming a heat conductive plug to channel heat away from devices on a substrate, while high temperature processes are performed on a stacked semiconductor layer. The ability to use high temperature processes on the stacked semiconductor layer without adversely effecting devices on the substrate allows the formation of a high quality single-crystalline stacked semiconductor layer. The high quality single-crystalline semiconductor layer can then be used to fabricate improved thin film transistors.
