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.

Sell & recycle any USB storage device or Digital Camera Card & Save the environment

Synopsis: Sell/recycle any flash storage device that you have with flash-based memory. Any cards or USB sticks, digital camera cards as Secure Digital (SD), CompactFlash, SmartMedia, MiniSD, MicroSD, MMC and Multimedia Card. In general, any storage device that still works, or can also be broken.

Nowadays modern computers both portable and desktop computers come with built-in slot SmartMedia and not just at the corner of the world of desktop computers and laptops, but the ball pure digital camera, storage devices, based on flash today taking its monopoly is the ultimate "electronic film" with several advantages, quiet, faster, lighter, larger and with no moving parts; Moreover, it is overwritten.

Components: A SmartMedia or any flash memory card or USB device consists of Microchips to 1-4 NAND flash EEPROM. Electrically Erasable Programmable Read-Only Memory is a semiconductor chip nonvolatile memory that can retain the stored information even when not powered. Semiconductorthese are solid and its electrical conductivity can be checked statically or dynamically. Semiconductors are identical to, but they are insulators in Silicone and is the main raw material for all these microchips.

Semiconductors production and use of dangerous substances: materials preparation semiconductor requires high levels of chemical purity as well as a small existence of impurities can have large effects on the properties of the chips. Moreover, these materials must be doped with other elements to adjust its electrical response as a carrier current controlling the number and the allegations to be positive or negative.

Due to this requirement of high-purity chemical semiconductor devices require subjects must go through the processes of purification by the merger of King-solidification through several chemical reactions to produce these modern marvels.

More then eight weeks of production is required for the processing of these products through multiple chemical processes and disposition process such as chemical vapor deposition, chemical-mechanical planarization and ion implantation, etc. Altogether these USB devices and memory cards of digital camera (flash memory chip) must go though over 300 sequenced processing steps and eight or more levels of the main procedures of compounds.

In this process many toxic materials and harmful chemicals are used as a catalyst to purify them. These substances primarily as listed below are the major pollutants and are one of the leading causes of cancer and genetic diseases that we face today and our children will face tomorrow.
Poisonous elements such as arsenic, boron, antimony and phosphorus; poisonous compounds like arsine, phosphine and silane. Highly reactive liquids, such as hydrogen peroxide, fuming nitric acid, hydrofluoric acid and sulfuric acid.

Computer recycling and the environment

Today we eProvided.com 's are apprehensive about the wastes that are generated from electronic products. Those little silicon wafer that allow computers, digital cameras, gadgets, etc. to function, are insatiable abuser of chemicals, water, fossil fuels and gases such as nitrogen. Only to produce a single microchip semiconductor , requires more than three pounds of fossil fuels, nearly a quarter pound of toxic chemicals, seventy pounds of water and over a pound of nitrogen and all have direct negative effect & for our health; Also, are the first components for cancer, disorders of the nervous system, reproductive health and disfunctions.

Now Imagine, the total number of these cards were produced this year, 115.7 million in 2006 and 88. 2 million in 2005. Linear in this figure are the effects on the environment.

Therefore, if you are a user of SmartMedia, SD Card, CompactFlash cards, USB drives, USB Thumb drives, digital cameras and other devices including the latest gadgets and gizmos like MP3 players and Digital Voice Recorder, your liability for environmental risks today. These products all use flash memory chips in Silicon.
