Fabrication and development of InP HEMTs on silicon substrate based on a new integration technique
Paper in proceeding, 2026

Current methods for transferring III-V technology onto silicon are based on wafer bonding techniques. Here we explore fabrication applicability of traditional InP-based High Electron Mobility Transistors (InP HEMTs) on InP-on-Si (InPoSi) wafers developed by Smart Cut, a method for transferring InP onto Si that reduces cost and fabrication complexity. We fabricated 100-nm gate length InP HEMTs, including test structures and Hall bars on both InPoSi and InP wafers. Transfer Length Method (TLM) measurements for InPoSi and InP bulk wafers showed comparable contact and sheet resistances. These preliminary results show that InP HEMTs can be fabricated on InPoSi.
