초록
Development of ArF Photo-lithography process has proceeded with the increase of numerical aperature (NA) and the decrease of resist thickness. It makes many problems such as cost and process complexity. A novel spin-on hard mask system is proposed to overcome many problems Spin-on hard mask composed of two layers of siloxane and carbon. The optical thickness of two layers is designed from reflectivity measurement at specified n, k respectively. The property of photo-resist shows different results according to Si contents. Si-contents was measured XPS(X-ray Photoelectron spectroscopy).
