    摘要: Provided is a method of depositing a metal nitride film having a multilayer structure and different deposition speeds on a substrate. The method is performed by forming a first lower metal nitride film on the substrate at a first deposition speed, forming a second lower metal nitride film on the first lower metal nitride film at a second deposition speed, and forming an upper metal nitride film having a large content of nitrogen (N) on a lower TiN film which is formed by the forming of the first lower metal nitride film and the second lower metal nitride film, at a third deposition speed, to improve stability with respect to exposure to air/moisture. The deposition speed of the metal nitride film having a multi-layer structure satisfies a relationship that the second deposition speed ≧the first deposition speed ≧the third deposition speed.

    摘要: Disclosed is a method of depositing thin films, in which the thin films are continuously deposited into one chamber and 1-6 wafers are loaded into the chamber. In the method, a process gap between a shower head or a gas injection unit and a substrate is capable of being controlled. The method comprises (a) loading at least one substrate into the chamber, (b) depositing the Ti thin film onto the substrate, adjusted so that a first process gap is maintained, (c) moving a wafer block so that the first process gap is changed into a second process gap in order to control the process gap of the substrate upon which the Ti thin film is deposited, (d) depositing the TiN thin film onto the substrate, moved to set the second process gap, and (e) unloading the substrate upon which the Ti/TiN thin films are deposited. If it is possible to continuously deposit Ti/TiN thin films on 1-6 substrates in one chamber, it is possible to set only one chamber among 4 chambers in a PM period, thereby an operating ratio of a cluster tool can be significantly improved. When Ti/TiN is continuously deposited in one chamber, the time needed to move a substrate from a Ti chamber to a TiN chamber is reduced, thus treatment efficiency of the substrate per unit time is significantly increased.
