What are the Semiconductors that have been boiling up in recent days? Let's take a look together next.   All objects in life can be roughly divided into three categories based on their conductivity: Conductors, Semiconductors, and Insulators.   The outermost electrons of a conductor easily break free from the atomic nucleus and become free electrons. Under the action of an external electric field, they move in a directional direction, forming an electric current. Their conductivity is very good, and they are called conductors. High valence elements (such as inert gases) or polymer materials (such as rubber), whose outermost electrons are strongly bound by atomic nuclei and difficult to form free electrons, have extremely poor conductivity and are called insulators.   ASML 4022.470.51162 Laser Sensor At Rockss Automation, we sell semiconductor accessories and welcome your purchase.    The commonly used semiconductor materials, silicon (Si) and germanium (Ge), are both tetravalent elements, and their outermost electrons are neither as easy to break free from the atomic nucleus as conductors, nor as tightly bound by the atomic nucleus as insulators. At room temperature, their conductivity is between the two.   In the semiconductor with crystal structure, when specific impurity elements are artificially doped, the conductivity is controllable. Moreover, under the conditions of light and thermal radiation, its conductivity still has obvious changes. These special properties determine that the semiconductor can be made into various electronic devices.    AMAT 0150-00743 Probe      Overall, Semiconductor is a material product typically composed of silicon, with higher conductivity than insulators such as glass, but lower conductivity than pure conductors such as copper or aluminum. Impurities (known as doping) can be introduced to alter their conductivity and other properties to meet the specific needs of the electronic components they reside in. Semiconductors, also known as semiconductors or chips, can be found in thousands of products, such as computers, smartphones, devices, gaming hardware, and medical devices.      Introducing Rockss Automation – your one-stop shop for all your semiconductor component needs.From microprocessors to memory modules, we have it all.

Semiconductors can be divided into first, second, and third generation semiconductors based on different substrate materials. The first generation semiconductors use silicon (Si) and germanium (Ge) as substrate materials and are most widely used. The second generation semiconductors use gallium arsenide (GaAs) as substrate materials, while the third generation semiconductors use gallium nitride (GaN) and silicon carbide (SiC) as substrate materials. According to specifications, semiconductors can be divided into military grade, automotive grade, industrial grade, and civilian grade, which have different temperature adaptability and anti-interference capabilities. In addition, the World Organization for Semiconductor Trade Statistics (WSTS) categorizes all semiconductors into four major categories based on their structure and function: integrated circuits, discrete devices, optoelectronic devices, and sensors.   LAM 27-326390-00 Manual Operator   First generation semiconductor The first generation of semiconductors mainly referred to Si and Ge. In the 1850s, Ge dominated the semiconductor market, mainly used in low-frequency, low voltage, medium power transistors and photodetectors. However, Ge semiconductor devices were not resistant to irradiation and high temperatures, and were gradually replaced by Si devices in the 1860s. Nowadays, Si accounts for over 95% of the semiconductor device market, and almost 100% of integrated circuits use Si materials. Given the maturity of the Si industry and the high reliability of Si based devices, Si will continue to maintain its leadership and core position in the semiconductor industry in the 21st century. However, Si materials also have limitations in their physical properties, such as limited applications in optoelectronics and high-frequency high-power devices   Second generation semiconductor There are many second generation semiconductors, mainly including binary and Ternary compound semiconductors composed of III-V family, such as GaAs, lnSb, GaAsAl, etc; Solid solution semiconductors, such as Ge Si; Amorphous semiconductors, such as amorphous Si, amorphous oxides (such as IGZO), etc; Organic semiconductors, such as copper phthalocyanine. The second generation of semiconductors is mainly used for producing high-speed, high-frequency, high-power, and light-emitting electronic devices, and has a complementary relationship with the first generation of semiconductors. In addition, the second generation semiconductor is also an excellent material for making high-performance microwave, millimeter wave and light-emitting devices. With the rise of information technology, it is widely used in optical communication, mobile communication, and satellite communication. However, second-generation semiconductors also have prominent drawbacks: GaAs and InP are scarce materials, very expensive, and toxic, polluting the environment.   Sumitomo CMC550011ABWG01 Main Control Card Third generation semiconductor The third generation of semiconductors generally refers to wide bandgap semiconductors, with the main representative materials being SiC, GaN, AlN, and ZnO. The bandgap width of these materials is very large, generally greater than 2.3 eV, such as SiC 3.2 eV and GaN 3.4 eV. The wide bandgap gives third-generation semiconductors a significant breakdown electric field. In addition, third-generation semiconductors also have the characteristics of high thermal conductivity, high electron saturation rate, greater radiation resistance than Si, and can be applied to high-power devices. Therefore, third-generation semiconductors are mainly used in semiconductor lighting, lasers, detectors, and high-power and radiation resistant electronic devices. With the rise of 5G communication, third-generation semiconductors have also made a difference in the field of 5G communication. The most popular GaN fast charging device currently sold is the third-generation semiconductor GaN.   Advanced Energy 3152352-103 Power Supply   Rockss Automation Co., Ltd. is dedicated to providing high-quality semiconductor components, as well as expert sales and maintenance services.
