the microchip or silicon chip has completely changed the color of
the electronic world by providing a new direction to it. it has lead
to the invention of electronic calculators, personal computers,digital
watches and microwave ovens.
the silicon chips are tiny crystals of silicon which contain large
number of electronic components. silicon is the most abundant element
on earth as the crust of the earth is largely made of silicon. but
silicon is not always found in free state as it always combined with
one or more additional elements. in an one sq.cm chip, about one
million electronic components can be squeezed. the size of chip is
smaller than our fingertips. they can be made to carry very small
electrical circuits
