  • Patent number: 11597993
    Abstract: A MgO layer is formed using a process flow wherein a Mg layer is deposited at a temperature <200° C. on a substrate, and then an anneal between 200° C. and 900° C., and preferably from 200° C. and 400° C., is performed so that a Mg vapor pressure >10?6 Torr is reached and a substantial portion of the Mg layer sublimes and leaves a Mg monolayer. After an oxidation between ?223° C. and 900° C., a MgO monolayer is produced where the Mg:O ratio is exactly 1:1 thereby avoiding underoxidized or overoxidized states associated with film defects. The process flow may be repeated one or more times to yield a desired thickness and resistance×area value when the MgO is a tunnel barrier or Hk enhancing layer. Moreover, a doping element (M) may be added during Mg deposition to modify the conductivity and band structure in the resulting MgMO layer.

  • Patent number: 11597999
    Abstract: The present disclosure relates to a method and device for decreasing generation of surface oxide of aluminum nitride. In a physical vapor deposition process, the aluminum nitride is deposited on a substrate in a deposition chamber to form an aluminum nitride coated substrate. A cooling chamber and a cooling load lock module respectively perform a first stage cooling and a second stage cooling on the aluminum nitride coated substrate in vacuum environments, so as to prevent the aluminum nitride coated substrate with the high temperature from being exposed in an atmosphere environment to generate the surface oxide. The method and device for decreasing the generation of the surface oxide of the aluminum nitride can further eliminate crystal defects caused by that gallium nitride is deposited on the surface oxide of the aluminum nitride in the next process.
