Abstract:

This paper presents a review of the application and technological progress of silicon-based precursors in advanced integrated circuit manufacturing. With the advancement of integrated circuit fabrication technology, particularly in the development of advanced processes such as 28nm/14nm/7nm, new requirements were being established for transistor devices, processes and materials. Silicon-based precursor materials played a pivotal role in epitaxial processes, lithographic processes, chemical vapour deposition (CVD) and atomic layer deposition (ALD) for wafer fabrication due to their high purity and specific performance parameters. The article analyzed and discussed the current application status, research progress, as well as synthesis and purification process technologies of several major silicon-based precursor materials, including pentachloroethylsilane (PCDS), diethoxymethylsilane (DEMS), diisopropylaminosilane (DIPAS), hexamethyldisilazane (HMDS), ethyl orthosilicate (TEOS), monochlorosilane (MCS), trimethylsilylamine (TSA), bis(tert-butylamino)silane (BTBAS) and others.

Key words: silicon-based precursors, advanced integrated circuits, CVD, ALD, synthesis process, purification technology
