We have found that nitrogen incorporation in the gate-oxide, by implantation into the Si, degrades the low field inversion mobility. Although submicron transistors fabricated using nitrogen implantation have been reported to show higher drive current

In the fabrication of CMOS devices with sub-3 nm gate oxides, we have observed severe variation of the oxide thickness (t/sub ox/). For devices with 2.5 nm t/sub ox/ at the center of the channel, the physical t/sub ox/ ranges from 1.8 nm to 4.2 nm at

We have found that the total trapped negative charge in a thin gate-oxide at the point of breakdown is a strong function of the stress field. This observation is in direct contrast with previous reports in the literature. The field dependent behavior

Shallow trench isolation (STI) has become the standard isolation structure for sub-micron silicon CMOS technologies (Perera et al, 1995; Chatterjee et al, 1996). However, following the trend of device scaling, isolation for future device generations

A number of groups have reported that the stress-induced leakage current (SILC) follows a power law dependence on the stress time. In this study, we observed that the power-law behaviour is only an approximation of the fast rising part of a more comp

Recently, there has been strong interest in using the surface potential measurement (SPM) method to monitor plasma charging damage. This method is also called contact potential measurement (CPM). The appeal of this method is obvious, in that it is fa

The question of whether or not thinner gate oxide is less susceptible to plasma charging damage depends on a number of factors. One important factor is the definition of damage itself. The measurement method is linked to the definition of damage. Whe

Boron diffusion from p/sup +/-poly gate through thin gate oxide not only causes a transistor to degrade, but also reduces the reliability of the thin gate-oxide. This problem has been studied extensively. Since high concentration of boron is used in

Summary form only given. We have demonstrated that the threshold voltage shifts in closely spaced, dual-poly CMOS devices are virtually eliminated by using buried, low energy gate implants. The reduced thermal budget for gate activation, made possibl
