Abstract:
PURPOSE: A novel tungsten silylamide compound is provided to have thermal stability and high volatility, thereby easily manufacturing a thin film containing high quality tungsten. CONSTITUTION: A tungsten compound is denoted by chemical formula 1. A method for preparing the tungsten compound of chemical formula 1 comprises the step of reacting a compound of chemical formula 2 and a compound of chemical formula 3. A thin film containing tungsten is grown by chemical vapor deposition (CVD) or atomic layer deposition (ALD) using the tungsten compound.
Abstract:
PURPOSE: A method for manufacturing a zinc tin oxide thin film is provided to form various zinc tin oxide thin films by controlling compositions. CONSTITUTION: A substrate is introduced into a deposition chamber. A zinc tin oxide thin film is manufactured by supplying tin, oxygen, and zinc. The zinc tin oxide thin film is manufactured by a chemical vapor deposition method or an atomic layer deposition method. The tin, the oxygen, and the zinc are supplied at the same time in the chemical vapor deposition method. The tin, the oxygen, and the zinc are alternatively supplied in the atomic layer deposition method.

Abstract:
PURPOSE: A pressure vessel for growing a single crystal is provided to easily replace a liner by including a constant taper part in the inner wall of an external vessel and an outer wall of an inner liner. CONSTITUTION: A pressure vessel body(120) is made of heat resistant alloy. A liner(110) is made of corrosion resistant materials and is inserted into the pressure vessel body. A lower support stand(130) passes through the lower side of the pressure vessel body and supports the lower side of the liner. A liner is separated from the pressure vessel body by upwardly pushing and raising the lower support stand.
