Mo may replace HVM applications, which could reduce future WF6 supply strains
San Diego, CA, July 26, 2023: TECHCET — the electronic materials advisory firm providing business and technology information on semiconductor supply chains — has announced that Semiconductor Precursor revenues are continuing to see high growth, with 5-year CAGR’s of 7% for metal, 5% for high-k, and 8% for dielectrics. Growth is influenced by the increasing interest and need for new materials for ALD and CVD processes. Device producers continue to look for new manufacturing solutions designed to improve cost and performance, and ALD/CVD solutions are at the forefront of such efforts.
Tungsten (from WF6 precursor) usage is highly driven by vertical scaling of 3DNAND and increased wafer start numbers in all segments. WF6 supply/demand is expected to stay in balance through 2023. However, TECHCET is anticipating supply of WF6 to become constrained by 2025 with threat of shortage in 2026 (as shown below). Possible shortages could be mitigated if molybdenum (Mo) solid precursors start replacing WF6 and transition from R&D to HVM. Implementation of Mo is still uncertain as fabs will need to see cost and performance equal to, or better than WF6, as indicated in TECHCET’s new ALD/CVD Precursors Critical Materials Report™.
.Other critical areas of technology change for improved devices include new materials for transistors such as high-κ gate dielectrics, metal gate electrodes, strain/stress epi of the channel and channel materials, memory cells and high-κ capacitors, interconnect wiring, barriers, seed layers, capping, insulators, and photolithography (with associated patterning techniques). Emerging challenges are driven by continued dimensional scaling addressed with materials (e.g., Hf, Zr, La, Co, Ru, Mo), and processes (e.g., ALD and plasma-assisted methods.
