Reflow Soldering Capability Improvement by Utilizing TaN Interfacial Layer in 1Mbit RRAM Chip [PDF]
Micromachines, 2022 We investigated the thermal stability of a 1Mbit OxRRAM array embedded in 28 nm COMS technology. A back-end-of-line (BEOL) solution with a TaN–Ta interfacial layer was proposed to eliminate the failure rate after reflow soldering assembly at 260 °C.

Mechanically Robust Dicing-Free Thermoelectric Module Fabrication Using Anion-Cation co-Doped Bismuth Tellurides. [PDF]
SmallNaCl co‐doping effectively enhances the thermoelectric performance of p‐type Bi–Sb–Te (BST) alloys through simultaneous Na+ substitution at Sb sites and Cl− substitution at Te sites, inducing local lattice distortion and defect engineering. At low doping levels, carrier transport is optimized by tuning carrier concentration and suppressing antisite ...
