    摘要: There are provided methods of fabricating a metal silicate layer on a semiconductor substrate using an atomic layer deposition technique. The methods include performing a metal silicate layer formation cycle at least one time in order to form a metal silicate layer having a desired thickness. The metal silicate layer formation cycle includes an operation of repeatedly performing a metal oxide layer formation cycle K times and an operation of repeatedly performing a silicon oxide layer formation cycle Q times. K and Q are integers ranging from 1 to 10 respectively. The metal oxide layer formation cycle includes the steps of supplying a metal source gas to a reactor containing the substrate, exhausting the metal source gas remaining in a reactor to clean the inside of the reactor, and then supplying an oxide gas into the reactor. The silicon oxide layer formation cycle includes supplying a silicon source gas, exhausting the silicon source gas remaining in the reactor to clean the inside of the reactor, and then supplying an oxide gas into the reactor.

    摘要: A semiconductor device may include a semiconductor substrate having a first region and a second region. The nitrogen-incorporated active region may be formed within the first region. A first gate electrode may be formed on the nitrogen-incorporated active region. A first gate dielectric layer may be interposed between the nitrogen-incorporated active region and the first gate electrode. The first gate dielectric layer may include a first dielectric layer and a second dielectric layer. The second dielectric layer may be a nitrogen contained dielectric layer. A second gate electrode may be formed on the second region. A second gate dielectric layer may be interposed between the second region and the second gate electrode. The first gate dielectric layer may have the same or substantially the same thickness as the second gate dielectric layer, and the nitrogen contained dielectric layer may contact with the nitrogen-incorporated active region.
