What is monolithic ic?
An IC or integrated circuit consists of a chip ("die") and plastic or ceramic packaging to protect the die from mechanical and (some) electrical damage. An IC with more than one die is usually called a "hybrid" IC. A "monolithic" IC is just a plain old one-die IC, but it implies that functions from a number of ICs have been incorporated into that one IC. One form of monolithic IC is where the functions of a powerful graphics processor is put on the same die as a CPU. An SOC ("System On a Chip") is another trend in monolithic ICs. "Monolithic" is something of a transitional term. Floating point, memory management, and processing units all used to to be on separate ICs. Now they are all on the same IC, but we don't call them "monolithic" any more.
Advantages of monolithic and hybrid IC?
low cost high reliability
What is meant by metallization in IC fabrication?
Metallization is a technique used to form metal contacts and interconnects in the fabrication of ICs.
What is lithography in IC fabrication?
Lithography is a technique used to make patterns on semiconductor materials.
What is epitaxy in IC fabrication?
Its the ordered growth of a material on the same material such that there vl be no any type of mismatch in their interface.
Is IC741 a hybrid ic?
no, the 741 opamp is a monolithic IC.

Why vlsi becoming popular?
VLSI deals with fabrication of an IC (integrated circuit) or a chip. The design and fabrication of an IC is vital in prototyping any system. In order to implement any application, the basic requirement is an IC. Hence, VLSI which is used to fabricate bulk number of ICs is becoming popular.
