Wet and Dry Etching - University of California, Davis

Silicon dioxide or silicon nitride is usually used as a masking material against HNA. As the reaction takes place, the material is removed laterally at a rate similar to the speed of etching downward. This lateral and downward etching process takes places even with isotropic

VERILOG 6: DECODER DESIGN EXAMPLES

www.ece.ucdavis.edu

Decoder Design Using Predecoding •Example: 256-output (8 input bits) with predecode –Ex: take groups of 2 input bits •Four possibilities; activate one of four wires (use 2 INVs, 4 ANDs) –Wires along array: 22 * (8/2) = 4 groups of 4 = 16 (same as non-predecoded) –Each output uses a 4-input AND gate (much faster)
