A Study of Parameters Related to the Etch Rate for a Dry Etch

AbstractIntroductionMaterials and MethodsResults and DiscussionConclusionAcknowledgmentsThe characteristics of the dry etching of :H thin films for display devices using sf 6/O2 and NF3/O2 were investigated using a dual-frequency capacitively coupled plasma reactive ion etching (CCP-RIE) system. The investigation was carried out by varying the RF power ratio (13.56 MHz/2 MHz), pressure, and gas flow ratio. For the :H film, the etch rates obtained using NF3/O2 were higher than those obtained using gaz sf6/O2 under various process conditions. The relationships between the etch rates and the usual monitoring parameters—the optical emission spectroscopy (OES) intensity of atomic fluorine (685.1 nm and 702.89 nm) and the voltages and —were investigated. The OES intensity data indicated a correlation between the bulk plasma density and the atomic fluorine density. The etch rate was proportional to the product of the OES intensity of atomic fluorine and the square root of the voltages on the assumption that the velocity of the reactive fluorine was proportional to the square root...Get price
