Chip Development

         This may be one of the interesting things for the students to know about the
methods or procedure of development of modrn Ics are built on wafer thin slice
of extremely ofdevelopment purified silicon crystal chipsDevelopment  of a chips
is summarised in points below:

  1. The high purity polycrystalline silicon is the raw material used to manufacture                                    integrated circuit chips the heart if computer. 
  2. Under computer control the chunks are melted in a crucible and slowly drawn                                     upward forming cylinderical bulb or crystal. 
  3. The crystal is sliced into thin wafers and polished to a mirror finish. 
  4. Each chips on the wafer is then electrically tested.
  5. The wafer are then diced or cut into individual chips.
