Etching of Metallic & Dielectric Films in VLSI Technology
Journal Title: International Journal of Advanced Research in Computer Engineering & Technology(IJARCET) - Year 2012, Vol 1, Issue 4
Abstract
In the present paper we discuss the isotropic etching of various films such as Aluminum, Titanium, Silicon dioxide& Silicon Nitride The second section of this paper contains anisotropic etching of Silicon using Silicon Nitride as a mask. Various types of etchant are available.The etch rate depends upon the pH, concentration and temperature in anisotropic etching. In isotropic etching etch rate depends upon concentration of the acidic medium.
