Semiconductors are widely used in consumer electronics, communication systems, medical instruments and other fields. For example, diodes are devices made of semiconductors. The importance of semiconductors is enormous in terms of technology and economic development
Substances and materials in nature can be divided into three categories: conductors, semiconductors and insulators according to their conductivity. The resistivity of semiconductor is in the range of 1m Ω· cm ~ 1g Ω· cm (the upper limit is taken according to Xie jiakui's electronic circuit, and 1/10 or 10 times of it; because the angle mark is not available, the current description is used temporarily)
Commonly used electronic components are: resistance, capacitance, inductance, potentiometer, transformer, diode, triode, MOS tube, integrated circuit, etc.
Components: products that do not change the molecular composition of raw materials during processing can be called components.
Integrated circuit (IC), sometimes called chip or microchip, is a semiconductor wafer on which thousands of micro resistors, capacitors and transistors are manufactured. An integrated circuit can function as an amplifier, oscillator, timer, counter, computer memory, or microprocessor. Specific ICs are classified as linear (Analog) or digital according to their intended applications.
At the end of April 2022, we opened a special column called "when the weather turns good, we will copy the bottom 2022". By the end of June, we have focused more on the new energy industry tracks, including the upstream and downstream industrial chain of lithium batteries for new energy vehicles
