双二乙氨基硅烷或N,N,N ′,N ′-四乙基硅烷二胺,或BDEAS是一种有机硅化合物,外观为透明液体,主要用作化学中间体,是一种广泛用于先进半导体和材料应用的高纯硅前体。(二乙氨基)硅烷(BDEAS),纯度≥99.99%,以痕量金属计(使用99.99%-Si),适合作为用于半导体器件制造的原子层沉积(ALD)和化学气相沉积(CVD)工艺中的硅前体。
Bis(diethylamino)silane or N,N,N′,N′-Tetraethylsilanediamine, or BDEAS can be used
- Bis(diethylamino)silane or BDEAS is commonly used to deposit silicon oxide (SiO₂) and silicon nitride (SiNx) films on semiconductor wafers via ALD and CVD. These films serve as insulating layers, passivation layers, and dielectric materials in microelectronics.[,]
-Bis(diethylamino)silane or BDEAS enables low-k dielectric deposition and is important in advanced integrated circuits, including 3D ICs and advanced chip packaging, because of its capacity for ultra-high purity and selective film growth.[]
