Vertical segregation within the active layer is important to the device performance.
Are you sure you're not confusing your own network latency with the device performance?
However, at ratios above 0.3 device performance drops off.
Producers have started issuing reports with far more detailed data on device performance.
Almost always, higher mobility leads to better device performance, with other things equal.
Another classification is less obvious, but has a strong influence on device performance:
Over time, specific device performance (and other conditions) may vary.
Some companies get most of their information about device performance from these scribe line test structures.
If this balance is thrown off even a little bit, the device performance will change radically.
These advantages translate to lower power consumption and enhanced device performance.
