Low power direction is the current advanced direction of integrated circuit design, mainly because the chip power consumption is too large, and turning off unnecessary modules has a significant extension of the use time. The group is based on both power supply and clock. Described by CPF, UPF. I feel that low power is the trend of the future.
Device and processThe direction is good, involving both the content of IC design and the content of the underlying process. Can go to a variety of IC design companies when the chip design engineer, can go to a variety of domestic microelectronics technology research institute, and can even go to a cadence type of IC simulation software development company.
LSI (Large scale integrated circuit), transistor number 1000 ~ 100000. VLSI (Very large scale Integrated circuit), transistor number more than 100,000. Two, according to the functional structure classification. Integrated circuits can be divided into analog integrated circuits and digital integrated circuits according to their functions and structuresDifference Difference: FRD chip is an abbreviation for FreeRecoveryDiode, which is a forward recovery diode. Refers to the IGBT chip InsulatedGateBipolarTransistor, is a kind of triode structure of power switch device.
3, OH is to prevent IGBT, FRD (fast recovery diode) overheating protection function. There is no temperature detection element on the insulating substrate inside the IPM, and the temperature Tcoh of the insulating substrate is detected (the protection action time of IGBT and FRD chips after abnormal heating is relatively slow).
4, U-IGBT U (groove structure) -IGBT is carved on the tube core, and the groove grid is formed inside the chip cell. After using the channel structure, the cell size can be further reduced, the channel resistance can be reduced, the current density can be improved, and the product with the same rated current and the least chip size can be manufactured.
5, in-depth exploration: The mystery of power artefact FRD The world of power devices is like a complex jungle, of which SGT-MOS, IGBT and FWD continuous current diode have their own characteristics.
IC is a class of electronic components; IC is equivalent to oranges (there are many kinds of oranges, and there are many kinds of ics), and electronic components are equivalent to fruits.
is not quite the same, the difference is that the IC is actually an integrated circuit, which contains many electronic components and ordinary electronic components are single electronic components. What they all have in common is electronics.
Integrated circuit is also known as ic, is a collection of a variety of electronic components on the silicon board to achieve a specific function of the circuit module Electronic components is a general term for components and devices. corpuscleComponent: refers to the finished product that does not change the molecular composition during production and processing in the factory.
- Different concepts: PCBA refers to the process of assembling various electronic components onto a printed circuit board, while IC refers to the technology and devices that integrate multiple electronic components on the same chip.
2, chip, also known as microcircuit (microcircuit), microchip, integrated circuit (IC). A small piece of silicon containing an integrated circuit, often part of a computer or other electronic device. chip (chip) is a general term for semiconductor components.
3, electronic chips and integrated circuit chips are not substantially different. A chip is a small piece of silicon containing an integrated circuit, often part of a computer or other electronic device. An integrated circuit is a tiny electronic device or component.
4. Semiconductors are the bridge of the electronic world, arising from the delicate balance of electrons in the outer layers of atoms. Electrons travel between energy levels, conductors conduct electricity because their electrons flow freely in a wide band, and insulators isolate current because they cannot move at full load.
5, the chip is the total semiconductor component productsSay. It is an integrated circuit (IC, complete circuit) carrier, which is divided by a chip. A silicon wafer is a small piece of silicon that contains an integrated circuit and is part of a computer or other electronic device. A semiconductor (semiconductor) is a material whose electrical conductivity at room temperature is between that of a conductor and an insulator.
