Hello.
I hope this answer is of help to someone.
First off, the single crystal of silicon, so-to-speak, is grown in a lab that is ultra clean and pure. It is done in a room called a, "clean room." This room is more clean than any you will ever encounter yourself unless you are a technician or engineer that works in such place, then, even at that there are places that only a robot can go.
A single crystal of silicon is used because there has to be one, continuous piece of crystal with no splices or anything like that. If there wasn't a single piece of crystal, there would be problems with electricity getting where it needs to go and where it doesn't need to go.
If you truly want to understand any or all of this, start out by googling this initial question and follow as many relevant links as you can.
What else can I help you with?
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 the function of crystal in IC?
Not sure what your question means. In an IC (Integrated Circuit) the circuit is etched onto a single crystal of Silicon. So the crystal forms the semiconductors within the IC. or Quartz Crystals are used in electronics as stable oscillators. They vibrate at precise frequencies, which can then be used for radio transmission or reception, or can form a time base for clocks or clock pulses, used for digital electronics.
What is lithography in IC fabrication?
Lithography is a technique used to make patterns on semiconductor materials.
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 are approaches of doping in IC fabrication?
Vacuum sublimation
Why single crystal Silicon is used for IC fabrication?
pure silicon is easily available cost is less efficient fabrication techniques for silicon processing better mechanical and physical properties of silicon integration with control and signal processing circuitry
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 a monolithic IC?
A monolithic IC is a type of "integrated circuit" electronic device (commonly referred to as a "chip") that contains active and passive devices (transistors, diodes, resistors, capacitors) that are made in and on the surface of a single piece of a single crystal semiconductor, such as a Silicon (Si) wafer. A process called "planar technology" must be used in the single block (monolith), and be interconnected to the insulating layer over the same body of the semiconductor to produce a solid integral monolithic-IC. If the devices are interconnected by bonding wires dangling above the chip, is not a monolithic-IC; it is a hybrid-IC. In monolithic-ICs, the devices (transistors, diodes, resistors and capacitors) are fabricated on the same single chip of a single Silicon crystal by PLANAR technology, and have ISOLATED p-n junctions, and have interconnections adherent to the insulator layers without shorting to the adjacent areas and each other.
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.
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 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?
