由於半導體元件越做越小,連接各元件的導線也越來越小,使得trench或vias的深寬比越來越大,因此增加金屬沉積時的準直性是必然的要求。通常都是使用準直器來增加粒子的準直度,但這樣同時也損失許多材料在準直器上,而Ionized PVD則是另外一種方法。此篇論文的研究主題Ionized PVD系統的電漿特性,包括電漿電位、電漿密度、電子溫度以及鋁原子的游離與外在參數如氣壓、RF power的關係。
另外,因為IPVD通常使用RF頻率的ICP電漿,因此發展有RF補償作用的Langmuir探針也是此篇論文的另一重點。
The trend of shrinking the size of semiconductor devices leads to high aspect ratio trench or vias. Thus the need for unidirectional flux of metal is urgent and IPVD (Ionized Physical Vapor Deposition) is a promising new method. In the paper, we discuss the relation of plasma characteristics ( plasma potential、plasma density、electron temperature) and outer parameters ( neutral gas pressure、RF power) of the IPVD system.
On the other hand, since the plasma is exited by using a 13.56MHz RF power supply, we have developed a RF compensated Langmuir probe to measure the plasma characteristics.
