Etching
WebAtomica offers both dry (RIE, DRIE, ion milling) and wet etching capabilities, where the process technologies need to be matched to the design requirements. Our Deep reactive ion etching (DRIE) capability allows anisotropic etching of silicon which is useful for etching of close-tolerance comb fingers, vias or holes, and trenches. WebConductor Etch System M-8000 Series is utilized for hard mask and silicon etching for 32nm and beyond. Hitachi High-Tech developed new process flows, such as double patterning and new material etch processes such as high-k dielectric/metal gate through JDP (Joint Development Program) with device makers and material / tool suppliers.
