Lam Research Introduces Dielectric Atomic Layer Etching Capability for Advanced Logic
Latest Flex(TM) System Provides Industry's First Dielectric ALE Process Running in Production
"From transistor and contact creation to interconnect patterning, a new level of precision is needed by logic manufacturers to continue scaling beyond the 10 nm technology node," said
To continue logic device scaling, chipmakers are adopting new integration schemes such as those using self-aligned contacts (SACs) in order to address issues like RC delay. As a result, contact etch has become one of the most crucial processes, directly impacting both wafer yield and transistor performance. In order to define critical device structures with high fidelity, the etch process requires directional (anisotropic) capability with ultra-high selectivity, while also delivering the productivity needed for manufacturing.
For next-generation logic and foundry applications, Lam's Flex dielectric etch systems offer the industry's most advanced capacitively coupled plasma (CCP) reactor, featuring a unique, small-volume design to deliver repeatable results. The latest system uses proprietary AMMP technology to enable ALE of dielectric films such as silicon dioxide (SiO2). This capability results in a 2x improvement in selectivity over previous dielectric etch technologies while delivering atomic-level control.
