Feasibility and Assumptions
Feasibility
- Hypothesis: If the “ideal” device covers large enough design-variable space, the behavior of the “real” device should fall somewhere in between, as long as the process/device physics is reasonably well understood.
- Challenge: It seems that there are simply too many (may be “infinite”) variables for the design space. And it is difficult to determine how “large” the database is “enough” for accurately predicting the device performance.
- Rebuttal: “What you can do if computer speed and memory capacities were infinite?” The real question is how we approach the problem and whether the effort is worth the investment.
Assumptions
- The physical models are valid in the region of the database to be constructed.
- The device performance can be predicted by interpolation of the TCAD data.
Potential problems
- Database range.
- Inverse modeling: multiple solution.
