For example for subm rule λ = 0. Vdd and gnd should abut (standard height) adjacent gates should satisfy design rules. Hence, the minimum channel length dimension is 2. Wells of different type, spacing = 8λ (2) rules for active area shown in figure below.

Minimum width = 3λ 2. Design rules extension rules width rules exclusion rule surround rule spacing rules • design rules are an abstraction of the fabrication process that specify various geometric constraints on how different masks can be drawn. The design rules are usually described in two ways: The mosis design rules are as follows : Gates operate independent of.

I they guarantee that the transfers onto the wafer preserve the topology and geometry of the patterns. Minimum separations, minimum and maximum widths, overlap rules In a 0.6 µm process, this corresponds to an actual width of 1.2 µm and a length of 0.6 µm. Layout design rules describe how small features can be & how closely they can be.

Minimum width = 10λ 2. I these rules are the designer’s interface to the fabrication process. Specify layout constrains in terms of a single parameter and thus allow linear proportional scaling of all geometrical constrains. Wells at same potential with spacing = 6λ 3.

Antenna rules specify the maximum area of metal that can be connected to a gate without a source or drain to act as a discharge element the design rule normally defines the maximum ratio of metal area to gate area such that charge on the metal will not damage the gate the ratios can vary from 100:1 to 5000:1 depending.

Mosis cmos design rules also include scmos, subm and deep rules variations. Wells at same potential with spacing = 6λ 3. The mosis rules are scalable λ rules. What is a layout design? Layout design is a schematic of the integrated circuit(ic) which describes the exact placement of the components for fabrication.
