VERILOG 6: DECODER DESIGN EXAMPLES

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)

Jul 19, 2018 · This etch will remove silicon dioxide. It will only attack silicon and silicon nitride at a very slow rate. Some metals etch in BOE (Titanium, Aluminium) some do not (Chromium, Gold, Platinum). You can mask a BOE etch with photoresist for a short etch (20 mins or so). If you etch longer, the photoresist will start to peel off.

7. Polysilicon and Dielectric Film Deposition

Silicon nitride is a barrier to sodium diffusion, is nearly impervious to moisture, and has a low oxidation rate. The local oxidation of silicon (LOCOS) process also uses silicon nitride as a mask. The patterned silicon nitride will prevent the underlying silicon from oxidation but leave the exposed silicon to be oxidized.

VLSI FABRICATION TECHNOLOGY

This appendix will consider only silicon-based (Si) technologies. Although other compound materials in groups III through V, such as gallium arsenide (GaAs) and aluminum gallium nitride (AlGaN), are also used to implement VLSI chips, silicon is still the most popular material, with excellent cost–performance trade-off.
