Abstract: This paper consisting of the general information about the VLSI followed by the history and development of the VLSI. MOORE's LAW is explained shortly and the designing of the VLSI circuits is explained by the design of VLSI by HIERARCHYSTRUCTURE. In this paper some of the general discussion on the current leakage reduction in the processors are discussed in which the reduction of current leakage by using switches are included and also we can reduce the current leakage in the circuit by using "sleep transistor". Sleep transistors are the transistor which turns off completely when the circuit is not in use. This is a very effective technique. After that some of the discussions about the problems in implementing the sleep transistors is also discussed which is very important while designing any circuit.
