Abstract: A method of fabricating a capacitor of a semiconductor device, includes forming a lower electrode on a semiconductor substrate, sequentially forming an aluminum oxide layer and a titanium oxide layer on the lower electrode, and forming an upper electrode on the titanium oxide layer, wherein the upper electrode crosses over the lower electrode. The titanium oxide layer is formed to have a thickness in a range of from about 2 Å to about 50 Å, and the upper electrode is formed at a temperature in a range of from about 150° C. to about 630° C. The temperature at which the upper electrode is formed is decreased as the thickness of the titanium oxide layer is increased to produce a capacitor of a semiconductor device having a minimized leakage current characteristic.

Abstract: A method for supplying a source gas to a processing chamber for forming a film on a substrate in the processing chamber includes: heating a carrier gas; bubbling the heated carrier gas in a liquid source disposed in a container to form a vapor source; and supplying a source gas including the vapor source and the heated carrier gas into the processing chamber for forming the film.

Abstract: A system and method for real time deposition process control based on resulting product detection, where the system and method detect an amount of at least one reaction product in real time, while the deposition process is being performed, the detected amount of reaction product is compared with a reference amount, and a comparison result is fed back in real time to adjust a supply of one or more reactants. The system and method provide real time control over the deposition process and/or reduce the number of wafers produced that do not meet processing target values.
