What is meant by metallization in IC fabrication?
Metallization is a technique used to form metal contacts and interconnects in the fabrication of ICs.
Examples of lithography?
lithography is basic demand to have set patterrn of any master pice to make its replica ones. when move to microelectronics , lithography deals with making pattern in IC by the help of masks for diffusion & metalisation purpose
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.
How is nanotechnology used?
Nanotechnology is currently a wide field of research and applications in fields ranging from biology to semiconductor fabrication. An example in biology is the design and fabrication of extremely small and sensitive chemical sensors. An example in semiconductors is the lithographic creation of IC chips.
Why inductor is not incorporated in an integrated circuit?
This difficulty arises due to the fact that the IC fabrication techniques are layer oriented which typically involve processes which are applied to multiple horizontal surfaces in a sequential fashion. However the inductive circuits has a "non-planar" configuration which typically has a continuous spiral shape. This particular spiral configuration thus prevents the IC fabrication to integrate the inductive circuits as part of the IC devices.
What are approaches of doping in IC fabrication?
Vacuum sublimation

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.
What is ic fabricationm?
Manufacturing of IC is known as Fabrication of IC.... it is fabricated from silica(sand)... Inside an IC u can see a small silicon sheet where the actual circuits are imprinted by a process... from that small sheet wires are drawn and fabricated into a IC......
What is direct lithography?
Direct lithography is a fabrication technique used to create patterns on a substrate without the need for masks or intermediate steps. It involves directly writing patterns using techniques such as electron beam lithography or laser lithography, allowing for high-resolution and customizable designs. This method is particularly useful in applications like semiconductor manufacturing and nanotechnology, where precision is crucial. Direct lithography can reduce production time and costs by eliminating the need for mask production.
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.
Diffusion in ic fabrication?
its the process of injecting ions of one material into other there are different types of diffusion substitutional and interstitial ...

Different technology used in fabrication of ic's?
If I am not mistaken, there are two distinct fabrication disciplines applied to integrated circuitry. Commercial specifications, (plastic) and Military specifications (ceramic). Although for purposes of manufacturing, and integration, the obvious reasons are to afford more tolerance when heat, shock, liquids, etc, are applied to the ic's and YES ceramic chips are able to handle the rigors of harsher environments.

What is the market share of lithography?
As of my last update in October 2023, the market share of lithography in the semiconductor manufacturing industry is significant, primarily dominated by a few key players like ASML, Canon, and Nikon. ASML, in particular, holds a substantial portion of the market due to its advanced EUV lithography technology, which is essential for producing cutting-edge chips. Overall, lithography technologies account for a considerable segment of the global semiconductor equipment market, reflecting their critical role in chip fabrication. For the most accurate and current figures, consulting recent market reports would be necessary.
