We Have Investigated The Effects Of Metal Gate Process Temperature On The Effective Work Function (W Eff) Of Mos Devices With All Ald Hfo 2 /Tin Gate Stack And Its Correlation With Grain Size Of Peald Tin Metal Gate Is Presented With Other Electrical Characteristics.
The effective work function (φ m,eff) of tan on sio 2 and hfo 2 are 4.4 and 4.6 ev, respectively. Oxygen anneals result in higher effective work functions for platinum on hfo2 than forming gas anneals. As in other absolute methods, the resulting electric current (here called photocurrent) is analyzed.
Material Work Function [Ev] Cs2.
Figure 2 shows the energetics of a. The split description corresponds to table 1. This increase in the work function might be attributed to the conversion of.
Subsequent Annealing In Forming Gas Returns The Platinum Work Function To A Value Comparable To That Measured Prior To The Oxygen Anneal.
Fig 3:relaxed structure of hfo2/sio2 for 0%, 50% and 100% la substitutional cases. The effective platinum work function is ̃4.6ev when annealed in forming gas. A short summary of this paper.

We Investigate The Schottky Barrier And Effective Work Function (Ewf) At Tin/Hfo 2 Interface Through Density Functional Calculations.
However, diffusion of oxygen to the pt /hfo2 interface increases the platinum work function to a value of ̃4.9ev. Each point shows the median of the distribution of the dies measured on two wafers per split. In ge mos devices with pt/hfo2 gate stacks were investigated by examining the impact of thermal treatment in forming gas (fg) and oxygen (o2) environments on the effective metal work function ( φm,eff) of pt gate electrode.
