Semiconductors are materials which have a conductivity between conductors (generally metals) and nonconductors or insulators (such as most ceramics). Semiconductors can be pure elements, such as silicon or germanium, or compounds such as gallium arsenide or cadmium selenide. In a process called doping, small amounts of impurities are added to pure semiconductors causing large changes in the conductivity of the material.

A semiconductor is an electronic component that utilizes conduction in the solid state and are most commonly manufactured as single discrete devices (such as diodes & transistors) or as integrated circuits (ICs) which may incorporate multiple devices within a single semiconductor substrate. Semiconductor materials vary greatly and include silicon, germanium, gallium arsenide and more, including organic semiconductor materials. Semiconductor materials can be physically manipulated to alter behavior of conductivity or by introducing electric & magnetic fields, heat, or light to achieve the desired result.

Due to their role in the fabrication of electronic devices, semiconductors are an important part of our lives. Imagine life without electronic devices. There would be no radios, no TV's, no computers, no video games, and poor medical diagnostic equipment. Although many electronic devices could be made using vacuum tube technology, the developments in semiconductor technology during the past 50 years have made electronic devices smaller, faster, and more reliable. It is clear that semiconductor technology has and will continue to play a major role in the development of the information age.

As semiconductors have evolved and become more powerful, they have propelled many industries forward into a technological age. They are still an expensive component in many devices, so their pricing and demand trends go a long way in determining the profit potential of companies that sell devices with semiconductors in them. Chips are made by the billions each year, and their sales & pricing trends are widely followed by analysts as a harbinger of technology-related profits.

A semiconductor is a substance, usually a solid chemical element or compound, that can conduct electricity under some conditions but not others, making it a good medium for the control of electrical current. The semiconductor industry is the aggregate collection of companies engaged in the design and fabrication of semiconductor devices. It formed around 1960, once the fabrication of semiconductors became a viable business. It has since grown to be a $335.2 billion industry in 2015.

IBS Electronics distributes a broad range of semiconductors. You'll find a wide range of ICs, DRAM, Flash, SRAM, Graphics Memory, MCP, Mask ROM, System LSI, signal conditioning, clock/power management, standard and high-performance logic ICs, transistors, rectifiers and diodes.
