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. Its conductance varies depending on the current or voltage applied to a control electrode, or on the intensity of irradiation by infrared (IR), visible light, ultraviolet (UV), or X rays.

Scope and Importance:
Since the invention of the transistor in 1947 followed by the commercial introduction of integrated circuits (IC) some twenty years later, progress in semiconductor technology has been driven primarily by the need to process information faster and more efficiently. Processing information is all dependent upon devices which can be turned "on" and "off" fast enough so that corresponding sequence of "1"s and "0"s can be executed billions of times per second. Since the Metal-Oxide-Semiconductor Field Effect Transistor (MOSFET) is the most effective device in carrying out these functions the progress in IC engineering was driven primarily by the improvements in MOS technology. During the last decade, several new, or renewed, applications of semiconductors have emerged as major players and hence, can be seen as technology drivers in the early 21st century.
Semiconductor lasers or laser diodes play an important part in our everyday lives by providing cheap and compact-size lasers. They consist of complex multi-layer structures requiring nanometer scale accuracy and an elaborate design. Their theoretical description is important not only from a fundamental point of view, but also in order to generate new and improved designs. The description can be done at various levels of accuracy and effort, resulting in different levels of understanding. It is common to all systems that the laser is an inverted carrier density system. The carrier inversion results in an electromagnetic polarization which drives an electric field. In most cases, the electric field is confined in a resonator, the properties of which are also important factors for laser performance.
Semiconductors conference aims to bring together leading academic scientists, researchers and research scholars to exchange and share their experiences and research results about all aspects of:
It also provides the platform for researchers, scholars and educators to present and discuss the most recent innovations, trends, and concerns, practical challenges encountered and the solutions adopted in the field of Semiconductors.
The Semiconductor Industry Association (SIA), representing U.S. leadership in semiconductor manufacturing and design, today announced that the global semiconductor industry posted record sales totaling $335.8 billion in 2014, an increase of 9.9 percent from the 2013 total of $305.6 billion. Global sales for the month of December 2014 reached $29.1 billion, marking the strongest December on record, while December 2014 sales in the Americas increased 16 percent compared to December 2013. Fourth quarter global sales of $87.4 billion were 9.3 percent higher than the total of $79.9 billion from the fourth quarter of 2013. Total sales for the year exceeded projections from the World Semiconductor Trade Statistics (WSTS) organization’s industry forecast. All monthly sales numbers are compiled by WSTS and represent a three-month moving average. Several semiconductor product segments stood out in 2014. Logic was the largest semiconductor category by sales, reaching $91.6 billion in 2014, a 6.6 percent increase compared to 2013. Memory ($79.2 billion) and micro-ICs ($62.1 billion) – a category that includes microprocessors – rounded out the top three segments in terms of sales revenue. Memory was the fastest growing segment, increasing 18.2 percent in 2014. Within memory, DRAM performed particularly well, increasing by 34.7 percent year-over-year. Other fast-growing product segments included power transistors, which reached $11.9 billion in sales for a 16.1 percent annual increase, discretes ($20.2 billion/10.8 percent increase), and analog ($44.4 billion/10.6 percent increase). Annual sales increased in all four regional markets for the first time since 2010. The Americas market showed particular strength, with sales increasing by 12.7 percent in 2014. Sales were also up in Asia Pacific (11.4 percent), Europe (7.4 percent), and Japan (0.1 percent), marking the first time annual sales in Japan increased since 2010.
