Semiconductors: An Important Element Available in Every Electronic Device!

Semiconductors are available in every electronic device which is used in the modern days including computers, telephones, radio etc. These semiconductors have entered every electronic device and now every human's life that are using these electronic gadgets. This has greatly increased the demand of semiconductor manufacturing companies. There are many top semiconductor manufacturing companies in the world who manufacture high quality silicon wafers. They are running business to provide various semiconductor turnkey solutions to the customers.

Today these semiconductors have become a part of our life and without these devices we can't survive. Whether you talk of computer which is lifeline or telephones which keep us connected, all have semiconductor in some form or the other. Basically, a semiconductor is a material which is having the special characteristics that enables it to conduct small amount of electrical current in a controlled manner. This electrical conductivity can be controlled either permanently or dynamically, depending on the requirement of the device it is used in. The devices like diodes, transistors and photovoltaic cells contain these semiconductors. It is found that these semiconductor materials have much lower resistance to the flow of electrical current in one direction than in another.

It's are made of several materials, not any single material forms these semiconductors. It is a known fact that semiconductors should not be a very good conductor of electricity, nor should it be a bad conductor of electricity. One amazing thing associated with these semiconductors is that their properties can be changed with the help of atoms. By adding or removing the atoms, one can do that. While creating semiconductors the materials used are many but the most widely used semi-conductor material is silicon. Other materials which aid to the development of this element are gallium arsenide, germanium and silicon carbide. Companies which provide semiconductor turnkey solutions make use of all of these materials in optimum quantity.

Whether you want integrated circuit test and assembly services or any other service related to semi-conductors, you will find numerous companies world over. Few of the popular names which are into the manufacturing of these semiconductors include AMI Semiconductor, Analog Devices, Amtel, Cosmic Circuits, Dynex Semiconductor, Elpida Memory, Fujitsu, IBM, Intel Corporation, Panasonic Corporation, Luxtera, Materials Research Corporation, Microchip Technology, National Semiconductor, Numonyx, Oramir, Sanyo, Seiko, Sitronics, Sony, Texas Instruments, Toshiba, Winbond to name a few. All these companies are related to the semiconductor manufacturing services, one or the other way.

Semiconductors Device Fabrication

Semiconductor device fabrication is the process by which chips are made. These chip are integrated circuits that are present in electrical and electronic devices and appliances. The process of semiconductor device fabrication is of multiple steps during which a wafer is created using pure semi conducting material. Usually Silicon is used to make integrated circuits. However, Gallium arsenide and Germanium are also used.

The entire fabrication process takes six to eight weeks. This includes the packaging of the chips.

A wafer is made from pure silicon ingot. These ingot are sliced into 0.75 mm thick wafers. Then they are polished to get a flat and even surface. After this many steps are required to make this wafer into an integrated circuit.

With time the integrated circuits have gone smaller and smaller, leading to them being produced in clean rooms. These clean rooms are called fabs. Fabs are pressurized with filtered air to remove even the smallest particle as it might rest on the wafer and make it defective. People working in the manufacturing facilities are required to constantly wear clean room suits to protect the chips from contamination.

With the demand increasing, semiconductors are now being manufactured in a number of countries like Ireland, Japan, Taiwan, Korea, Singapore, China and the US. Intel is the world's leading manufacturer and has manufacturing facilities in Europe, Asia and the US. Other top manufacturers of semiconductors are Samsung, Texas Instruments, Advanced Micro Devices, Toshiba, Taiwan Semiconductor Manufacturing Company, Sony and NXP Semiconductors.

According to US Industry & Market Outlook, there are approximately 5,000 semiconductor and electronic component manufacturers in the United States alone and they contribute $165 billion in terms of sales.

Fabrication of semiconductor device

Manufacture ofsemiconductor is the process by which chips are made. These chips are ICS that are present in appliances, and electrical and electronic devices. The process of manufacture of semiconductor is more steps, during which a wafer is created using pure material that leads seeds. Usually Silicon is used to make integrated circuits. However, gallium arsenide and germanium are also used.

The whole manufacturing process takes six to eight weeks. This includes packing of the chips.

A wafer is composed of pure silicon ingots. These ingots are sliced into wafers of thickness 0.75 mm. Then they are polished to achieve a flat surface and even. After this, many steps are required to make this into an integrated circuit wafers.

By the time the chips went smaller and smaller, which leads to their being produced in clean rooms. These s clean roomare called fabs. Fabs are pressurized with filtered air to remove even the smallest particle as might rest on wafer and make it bad. People who work in manufacturing plants are kept constantly wearing clean room to protect the chip from contamination.

With the increased demand semiconductors, are now being manufactured in a number of countries such as Ireland, Japan, Taiwan, Korea, Singapore, China and the United States. Intel is the leading producer in the world and has production plants in Europe, Asia and the United States. Other major semiconductormanufacturers are Samsung, Texas Instruments, Advanced Micro Devices, Toshiba, Semiconductor Taiwan Manufacturing Company, Sony Semiconductorand NXP.

According to us industry & Market Outlook, there are about semiconductor and 5,000 manufacturers of electronic components in the United States alone and contribute 165 billion dollars in terms of sales.
