Integrated Circuit |

|
An integrated circuit is one in which circuit
components such as transistors, diodes, resistors, capacitors
etc. are automatically part of a number of circuit components (e.g.
transistors, diodes, resistors etc.) and their in connections
in a single small package to perform a complete electronic
function. These
components are founded and connected within a small chip of
semi-conductor material. The following points are worth nothing
about integrated circuits: |

 |
|
(I) In IC, the various components are automatically part of
a small semi-conductor chip and the individual components
cannot be removed or replaced. This is in contrast to discrete
assembly in which individual components can be removed or
replaced if necessary.
(II) The size of an IC is extremely small. In fact, ICs are
so small that you normally need a microscope to see the connections
between the components. see the Fig. shows a typical semi-conductor
chip having dimensions 0.2mm × 0.2mm × 0.001mm.
It is possible to produce circuit containing many transistors,
diodes, resistors etc.On the surface of this small chip.
(III) No components of an IC are seen to project above the
surface of the chip. This is because all the components are
formed within the chip. |
