Abstract(in English) | We evaluated the properties of newly developed SiNx etch gas (SSY525). The gas indicated high selectivity as 30 ~ 60 for Poly-Si, and over 100 for SiO2, respectively. We introduced SSY525 to fabricate the FinFET which is the typical structure of Three Dimensional Metal Oxide Semiconductor Field Effect Transistors (3D-MOSFETs) and requires the high selectivity etching for the fabrication process. The 3D structure of FinFET fabricated by the etching process with SSY525 is superior to that with the CH3F gas which is conventionally used for the SiNx etching. |
