Silicon Disk is carried to a Cleaned
Room and 25 of Disks are Packed
in a Sealed Container and Passed
through 100’s of Manufacturing
Steps.
The Photolithographic technique
Transfers Circuit Structures to
Wafers.
Photosensitive resist is applied on
the silicon Disk.
Ion Implantation of Wafer’s is done where electrical properties is
specified by using its property of Conductivity…..
Dopants Atoms are injected in silicon atom & is distributed randomly in
lattice.
At high temp. these atoms acquires fixed position.
Random Dopants Atoms
Barrier Layer is applied which prevent short Circuit and after that cleaning is
done to remove tiny dust Particles.
