B. ENGINEERING OF INTERFACE PROPERTY (INTEGRATION TECHNOLOGY) 

Introducing new materials into conventional Si device structures requires various innovations in adjacent technologies to improve device performance. For example, replacing Si channels in transistors with TMD (e.g. MoS2) materials requires the study of interface properties such as channel doping, contact resistance, adhesion to surrounding materials, EOT scaling, and patterning methods. 

We demonstrate new concepts in interface engineering and develop integrated technologies with Si process compatibility to enable the performance required for future devices.

Applications: n-, p-type Modulation, Conductivity Control

Applications: Metal/Semi Contact, Ohmic Layer 

Applications: Lithography, Device Yield and Uniformity, Integration Reliability
