Mhm aio etch ultra low k
WebbTo reduce the RC interconnect delays and cross‐talk noise associated with the sub‐130 nm technology nodes, copper interconnects must be combined with low‐k interlayer dielectrics (ILDs) having dielectric constants k ⩽ 2. In order to obtain sufficiently low dielectric constants, pores are introduced into ILD materials thereby lowering the average density … Webb16 mars 2015 · Metal Hard Mask (MHM)-All In One (AIO) technology has been widely used in the process flow of copper inter-connect since 28 nm technology node and …

WebbAs semiconductor technology node continuously shrinks, Wet strip process works as a more important role beyond 45m. For RC delay concern, Ultra Low-K material is introduced to BEOL ILD (Interlayer Dielectric). After Trench First Metal Hard Mask All-in-One Etch, ULK film sidewalls are exposed during Wet strip. Wet strip needs to take … Webb27 feb. 2014 · MHM (Metal Hard Mask) AIO (All-In-One) etch is one of key BEOL (Back-End-Of-Line) processes for 40/45nm technology node and beyond. In this work, we focus on some key issues and solutions that we encountered during 40nm MHM AIO etch process development in HLMC.
Webb28 okt. 2014 · Indeed, low-k etching processes with a TiN hard mask need to be performed at higher temperature in fluorine-rich plasmas, 86 which tends to increase the porous low-k modification compared to processes developed for low-k etching with carbon-based masks. 39 In addition, some residues grow on the metal hard mask after … WebbUS Patent 8551202 from Cabot Microelectronics describes ultra-low abrasive-containing slurry formulation (0.25%) for ...
