1.Epitaxial wafers and chips are different in nature, purpose and use.
I. Different nature
1, epitaxial wafer: epitaxial wafer refers to a specific single crystal film grown on a substrate substrate heated to the appropriate temperature.
2, chip: chip is a solid state semiconductor device. The entire chip is encapsulated in epoxy resin.
Second, the purpose is different
1, epitaxial wafer: the purpose of epitaxial wafer is to add electrodes to the epitaxial to facilitate the sealing and packaging of the product.
2, chip: the purpose of the chip is to convert electrical energy into light energy for lighting.
Three, different uses
1, epitaxial wafers: epitaxial wafers are necessary for the middle process and the back process of the LED chip, without it, it is impossible to make a high brightness semiconductor.
2, chip: chip is the main material for making LED lamps, LED screen, LED backlight.
2.What is a chip?
A chip is a large-scale microelectronic integrated circuit, which can also be called an IC; i.e. a printed circuit version miniaturized to the nano (millionth of a millimeter) level. The front side of a conventional printed circuit board is usually a large number of various radio components, including triodes, diodes, capacitors, electrolytic, resistors, mid-cycle regulators, switches, power amplifiers, detectors, filters, etc. On the reverse side are the printed circuits and solder joints printed on the carbon fiber board. It is the main product of microelectronics technology and has a wide range of applications. The chips are embedded in our commonly used computers, mobile phones, electronic products, electronic instruments, etc.; people often refer to integrated circuits as chips.
3.The internal material composition of a chip
A chip is a generic term for a semiconductor component product, which is made of semiconductor material (mostly silicon), and which contains capacitors, resistors, diodes, and transistors. A semiconductor is a substance between a conductor, like copper, through which electricity can easily pass, and an insulator, like rubber, which does not conduct electricity.
