Confuse about the process

[ruanwang]

Hi all,
Today, my supporter ask me 1 question. But I'm not sure how to answer excectly. This is the question:
"What difference did you see moving from 45nm to 28nm in:
- Timing point of view
- Layout view
"
Please give me your opinion about it.
BR,
Wang.

Well when you move from one technology to another....timing should improve as the area reduces provided the voltage is reasonably scaled. Area definitely reduces so the silicon area reduces.

the main reason for going from 45nm to 28nm is less chip area meaning more chips per unit area... better performance.
