Extending CMOS Logic Alternate Channel Materials
-n-Ge & p-III-V -Nanowires -Graphene -Carbon Nanotubes Assess Materials Performance Gate materials Contacts Interfaces III-V Heterostructures (L. Samuelson, Lund Univ.) A. Geim, Manchester U. -Identify Novel Metrology & Modeling Needs D. Zhou, USC
6
Beyond CMOS Logic Materials & Interfaces
Charge Based States Other Than Charge Only Ferroelectric Polarization Spin State Individual or Collective Negative Capacitance FET Assess Ferromagnetic Materials, Dilute Magnetic Semiconductors Complex Metal Oxides Strongly Correlated Electron State Materials (FE, FM, FE & FM) Molecules Interfaces
7
ERM Device Material e-Workshops
Redox RAM Materials Deterministic and Conformal Doping Nanoscale Contact Resistivity Carbon Electronics (Nanotubes and Graphene) Spin Materials & Out of Plane MTJ Materials Strongly Correlated Electron Materials Modeling of Complex Transition Metal Oxide Properties
8
Lithography Materials
LER Rectification Ruiz, et. al. Science, 2008 Contact/Via Rectification Density Multiplication Stoykovich, et. al. Macromolecules, 2010 Continuing evaluation of novel resist for 193i and EUV LER Rectification to reduce LER and improve line CD control Contact/Via Rectification to reduce size and improve CD control Pattern Density Multiplication for high density smaller features
9
Survey on DSA Contact rectification and pattern density multiplication had the highest support Most industry responders had plans to evaluate DSA
10
Interconnect Materials
Interconnects Ultra-thin Barrier Layers (sub 2nm) NH2 terminated Self Assembled Monolayers (SAM) Graphene Via Wire Ultra low κ ILD Integration must be a significant focus Novel Interconnects & Vias Graphene, Carbon Nanotubes, Nanocomposites Workshops Ultralow k ILD: Completed Ultrathin Cu Barrier Layers: Completed
11
Assembly & Package e-Workshops
Residue Free Adhesives Insulating polymers with high in plane thermal conductivity [3-5 W/m-K] Electrically conductive flexible adhesive contact material for heterogeneous integration <200C process temperature photopatternable dielectric interposer Nanosolders with high electrical and thermal conductivity Novel EMI shielding materials (graphene, CNT, etc.)
12
Hexagon of Assembly Material Requirements
Examples Thermal Interface Mat. Mold Compound Underfill Adhesives Epoxy Functional Properties Moisture Resistance Adhesion Fracture Toughness Modulus CTE CTE depends on volume fraction Highly coupled Material Properties Apply novel materials to achieve optimal performance
13
ESH Challenges Materials needed to overcome significant technical challenges Low energy processes and new materials for low energy integrated circuits Few materials can meet requirements Some materials have known hazards or uncharacterized ESH properties Stimulate ESH research in uncharacterized materials Good risk management methods for materials ESH in Research, Development & Manufacturing Lifecycle Assessment & Management Efficient use of materials
