    silicon is raw material . silicon is purified by acid then melted and cooled

    1)how does mos transistor fabricated on silicon chip
    which layers are used to design source, drain and gate?

    there are different type of layer like metal layer, poly layer that are used to design transistor

    2)how does vdc and ground make on silicon chip?

    The gate is a conductive material on top of an insulating material (typically listed as silicon dioxide).

    if you want to fabricate silicon semiconductors, you need a lot of money and equipment. the layers are not glued together, they are usually difused into or onto the silicon.

    When I was young'un we made our own semiconductor by 'tickling' a chunk of germanium with a 'Cats Whisker' for a radio. :D

    I don't want to make silicon chip I am just trying to know how does transistor resistor, capacitor and Inductor fabricate on silicon chip with different layer
