背面功率分配网络方案--将集成电路中的功率传输转移到硅晶片的背面--有望帮助提高互补金属氧化物半导体(CMOS)电路的功率效率和性能,并有可能提高其扩展能力,特别是在基于硅纳米片的下一代晶体管技术中。然而,如何最好地实现背面功率分配并提供单元级扩展优势仍不清楚。来自 IBM Research 和三星电子的研究人员开发了一种直接背面接触方法,无需在源极和漏极上进行电源接触,也无需通常所需的深沟通孔。在纳米片宽度和 n 型到 p 型晶体管间距不变的情况下,直接背面接触方法与正面电源传输方案相比,可将电池高度降低 25%。为了制造这种结构,在源极和漏极外延层下形成了一个背面接触占位符,然后将其移除以形成背面接触。对采用正面和直接背面接触供电的器件的传输曲线进行比较后发现,n 型和 p 型器件的性能非常接近,这表明该工艺对器件性能的影响微乎其微。
