Journal ArticleDOI
Improvement in chemical mechanical polishing of 4H-SiC wafer by activating persulfate through the synergistic effect of UV and TiO2
Wantang Wang,Baoguo Zhang,Yunhui Shi,Tengda Ma,Jiakai Zhou,Ru Wang,Hanxiao Wang,Nengyuan Zeng +7 more
TL;DR: In this article, the effect of pH, persulfate concentration, and TiO2 dosage on CMP in-depth, and to ultimately optimize the polishing process was investigated for improving the CMP properties of Si-face of the 4H-SiC wafers.
Journal ArticleDOI
Improved chemical mechanical polishing performance in 4H-SiC substrate by combining novel mixed abrasive slurry and photocatalytic effect
TL;DR: In this paper, a mixed abrasive slurry (MAS) with photocatalytic effect in the SiC-CMP process is proposed to improve the performance of the slurry with or without the presence of UV irradiation.
Journal ArticleDOI
Improvement in dispersion stability of alumina suspensions and corresponding chemical mechanical polishing performance
TL;DR: In this paper , anionic triblock copolymer was used as the dispersant candidate to obtain alumina suspension with cost-effective, suspension-excellent, and uniform particle size.
Journal ArticleDOI
Roles and mechanistic analysis of adenine as a green inhibitor in chemical mechanical polishing
TL;DR: In this article, a new reagent, adenine (AD), was introduced as a corrosion inhibitor, which improved the surface morphology of copper and reduced the number of corrosion pits.
Journal ArticleDOI
An optimized passivation mechanism at the copper film recess for achieving efficient planarization of copper chemical mechanical polishing
Nengyuan Zeng,Doston Rustam o'g'li, Beknazarov Asqarali Jumanazarovich,Chenwei Wang,Khayrullayeva Nigorabegim Ne'matilloyevna,Chong Luo,Hongdong Zhao,Yuling Liu,Wantang Wang,Tengda Ma +8 more
TL;DR: In this paper, an improvement plan for the slurry to reduce the dishing caused during copper chemical mechanical polishing (CMP) of the interconnect structure was proposed. But the improvement plan was only applied to a small portion of the slurries.
