Analysis of Semiconductor Wafers16 April 2020
The wafer is the basic raw material for manufacturing semiconductor devices. Various circuit element structures can be fabricated on silicon wafers, thereby becoming integrated circuit products with specific electrical functions.
Diodes Tutorial: How to Test Diodes?11 April 2020
A diode is an electronic device made of semiconductor materials. The diode is one of the earliest semiconductor devices, and it is widely used, especially in various electronic circuits.
Introduction to Photonic Integrated Circuits and PIC Technology09 April 2020
The concept of the photonic integrated circuit is similar to the concept of electronic integrated circuits. However, electronic integrated circuits integrate transistors, capacitors, resistors, and other electronic devices, while PIC integrates various optical devices or optoelectronic devices, such as lasers, electro-optical modulators, photodetectors, optical attenuators, optical multiplexers/demultiplexers, and optical amplifiers.
Basic Introduction to Film Capacitors08 April 2020
The film capacitor is also called a plastic film capacitor. It uses plastic film as the dielectric. Depending on the medium, there are many types of capacitors, such as electrolyte capacitors, paper capacitors, film capacitors, ceramic capacitors, mica capacitors, and air capacitors. Film capacitors are widely used in analog signal cross-linking, power supply noise bypass (reverse cross-linking), and other places.
What is a Semiconductor?03 April 2020
Semiconductor refers to a material whose conductivity is between a conductor and an insulator at room temperature. Semiconductors are used in integrated circuits, consumer electronics, communication systems, photovoltaic power generation, lighting applications, and high-power power conversion.
What are Avalanche Diodes?02 April 2020
Avalanche diodes are semiconductor devices that use the avalanche multiplication effect and carrier transit time effect in the PN junctions to generate microwave oscillations. If a large reverse voltage is applied across the diode, the space charge region is widened from the N + P junction to the IP + junction. The electric field in the entire space charge region is the largest at N + P. If the electric field intensity exceeds the breakdown electric field in a small area near the N + P junction, then this phenomenon is called avalanche breakdown and the area where it occurs is the avalanche region.
Schottky Diodes: Principle, Functions, and Applications30 March 2020
Schottky diodes are metal-semiconductor devices made of precious metals (gold, silver, aluminum, platinum, etc.) A as the positive electrode and N-type semiconductor B as the negative electrode. Schottky diodes are unidirectionally conductive and can convert alternating currents into pulsed direct currents in a single direction.
What are the Testing Method and Types of Transistors?25 March 2020
A transistor is a semiconductor device that is commonly used in amplifiers or electronically controlled switches. It’s the basic building block that regulates the operation of computers, cell phones, and all other modern electronic circuits. Due to the fast response time and high accuracy, transistors can be used for a variety of digital and analog functions, including amplification, switching, voltage regulation, signal modulation, and oscillators.
What are Graphene Transistors?24 March 2020
Graphene is a two-dimensional crystal. Its structure is very stable because carbon atoms are arranged in hexagons and connected to each other to form a carbon molecule.
Semiconductor Materials:Types, Properties and Production Process21 March 2020
The semiconductor material is a kind of electronic materials with semiconductor properties and can be used to make semiconductor devices and integrated circuits. Various external factors such as light, heat, magnetism, and electricity will act on semiconductors and arouse some physical effects and phenomena, which can be referred to as the semiconductor properties. The majority of the base materials constituting solid-state electronic devices are semiconductors. Different types of semiconductor devices have different functions and characteristics because of the various semiconductor properties.
Working Principle and Characteristics of Zener diodes20 March 2020
Zener diodes are diodes that act as regulators. By using the reverse breakdown state of the PN junction, the current of the Zener diodes can be changed within a wide range while the voltage is unchanged.
What is a Digital Integrated Circuit and How Do We Use It?18 March 2020
Digital integrated circuits are digital logic circuits or systems made by integrating components and wires on the same semiconductor chip. According to the number of included gate circuits or components, digital integrated circuits can be divided into Small Scale Integrated (SSI) circuits, Medium Scale Integrated(MSI) circuits, Large Scale Integration (LSI) circuits, Very Large Scale Integrated (VLSI) circuits, and Ultra Large Scale Integration (ULSI) circuits.
