Question

Explain lambda rule and micron rule in vlsi

Answer 1

Lambda based design rules reason of explaining lambda properly is to make design itself independent of both process and fabrication and to permit the design to be re-scaled at future date when the fabrication tolerances are shrunk.

In microns sizes and spacing specified minimally.

Result in 50% area lessening in Lambda.

Micron is Industry Standard.

Answer 2

In the lambda rule, you need to allow the scaling on first order with the help of linearizing the whole resolution.

It is done in order to complete the wafer implementation.

On the other hand, it is also used to move the micron from 4 to 2.

In the micron rule, the minimum features of spacing and sizes are listed for all the masks.
