The process of making a chip is essentially the process of implementing a transistor on a silicon material. The transistor inside the chip can be abstracted into the following pattern: the transistor inside the chip is on top of the silicon crystal, which needs to have a silica insulation layer.On top of that is a layer of conductive silicon compounds (red in the image) that acts as a switch.
Chip production process generally includes semiconductor material preparation, wafer preparation, lithography technology, etching technology, cleaning and testing; The principle is based on the theory of semiconductor properties. Production process: Preparation of semiconductor materials The materials for chip manufacturing are semiconductor materials, such as silicon, germanium, etc. These materials need to be processed and treated in multiple steps before they become suitable for chip manufacturing.
The raw material wafer of the chip, the composition of the wafer is silicon, which is extracted from quartz sand, the wafer isPurified silicon (9999%). Then, some of the pure silicon is made into silicon crystal rods, which become the material for the manufacture of integrated circuits in time semiconductors. Slicing them is a special requirement for chip manufacturing. The thinner the wafer, the lower the production cost, but the higher the requirements for the process.
The specific process starts from the exposed area on the silicon wafer and puts it into a mixture of chemical ions. This process will change the conduction mode of the doped region, allowing each transistor to turn on, off, or carry data. A simple chip can only use one layer, but a complex chip usually has many layers. At this point, the process is repeated continuously, throughOpen a window to connect different layers. This is similar to the manufacturing principle of multi-layer PCBS.
Epitaxial sheet → cleaning → transparent electrode coating → transparent electrode pattern lithography → corrosion → de-gluing → Platform pattern lithography → dry etching → de-gluing → annealing →SiO2 deposition → Window pattern lithography →SiO2 corrosion → De-gluing → N-pole pattern lithography → Pre-cleaning → coating → stripping → annealing → P-pole pattern lithography → coating → stripping → Grinding → cutting → chip → Finished product testing.
The production process of the chip is generally divided into the following steps: Raw materials of the single chip: the raw materials of the chip production are mainly silicon wafersRush; (6) Mode 5 is a hardware triggered strobe pulse.

This article will solve for you one by one 8255 is the switch of the speaker 8255 is the switch of the speaker. Meaning of program delay The meaning of program delay is to pronounce a few seconds.
The CS enable end must first be set to low level and remain low until the conversion is complete. At this point the chip begins to convert work, simultaneously byThe processor injects the clock pulse to the CLK clock input terminal of the chip, and the DO/DI terminal uses the data signal selected by the DI input channel function. The DI end must be high until the first clock pulse dips, indicating the start signal.
Four: The working principle of the chip INTER 8253 is a programmable interval timer, which can also be used as an event counter. Each 8253 chip has three separate 16-bit counter channels, and each counter has six modes of operation, all of which can be counted in binary or decimal.

The D/A converter consists of an 8-bit input latch, an 8-bit DAC register, an 8-bit D/A conversion circuit and a conversion control circuit. The D/A conversion result is output in the form of current.
intel8253 is a programmable counter/timer made of NMOS process, there are several chip models, shape pins and functions are compatible, but the maximum count rate of work is differentDifferent, such as 8253 (6MHz), 8253-5 (5MHz) 8253 has three internal counters, respectively called counter 0, counter 1 and counter 2, their mechanism is exactly the same.
The working principle of the chip is: the circuit is manufactured on the surface of the semiconductor chip for calculation and processing. Integrated circuits have two main advantages over discrete transistors: cost and performance. The low cost is due to the fact that all the components of the chip are printed as one unit by photolithography technologyIt's not about making one transistor at a time.
"The working principle of the chip is to manufacture the circuit on the surface of the semiconductor chip for calculation and processing. Transistors have two states, on and off, represented by 1 and 0 respectively, and multiple transistors can produce multiple 1 and 0 signals, which are programmed for specific functions to process these letters and graphics.
The IC555 chip works on the principle that the output voltage of the two comparators controls the state of the RS trigger and the discharge tube. Add a voltage between the power supply and the ground, and when pin 5 is suspended, the voltage comparator C1 is the sameThe voltage at the phase input is 2VCC /3, and the voltage at the reverse input of C2 is VCC /3. The integrated circuit formed by
is placed on a plastic base to make a chip. Almost all chips seen today can be called IC chips. An integrated circuit is a tiny electronic device or component.
The main role of the chip is to complete the calculation, processing tasks, chip refers to the silicon chip containing integrated circuits, chips like the human brain is as flexible as the circuit can be manufactured on the surface of the semiconductor chip for calculationWith processing, the output of specific instructions and data. After the chip is powered on, it will produce a start command to transmit signals and transmit data, which can also make home appliances intelligent and is the core cornerstone of high-end manufacturing.
Principle: A chip is an integrated circuit, consisting of a large number of transistors. Different chips have different integration scales, up to several hundred million; As small as a few hundred transistors. Transistors have two states, on and off, denoted by 0. Multiple signals of 1s and 0s generated by multiple transistors that are programmed to perform specific functions (i.e., instructions and data) to represent or process letters, numbers, and colorsAnd graphics, etc.
The raw material wafer of the chip, the composition of the wafer is silicon, is extracted from quartz sand, and the wafer is the purified silicon element (9999%). Then, some of the pure silicon is made into silicon crystal rods, which become the material for the manufacture of integrated circuits in time semiconductors. Slicing them is a special requirement for chip manufacturing. The thinner the wafer, the lower the production cost, but the higher the requirements for the process.
Multiple 1 and 0 signals generated by multiple transistors that are programmed to represent or process specific functions (i.e., instructions and data)Letters, numbers, colors, graphics, etc. After the chip is powered on, it first generates a start instruction to start the chip, and then it continuously accepts new instructions and data to complete the function.
The various functions of the chip are realized by integrating multiple transistors and other electronic components together to form complex digital circuits. These digital circuits can perform logical operations such as binary addition, multiplication, comparison, etc. It can also realize data storage, such as storing programs and runtime data in the chip; Signal amplification can also be achieved, such as amplifying a weak signal into a signal that can drive the speaker.The word "chip" we must be familiar with it The working principle of the chip ? Usually in life we often hear this word, so do you understand the "chip" The working principle of the chip ? This guide will tell you the answer. Chip is a kind of semiconductor material, also known as "integrated circuit", the chip is used in our life is very wide range, our life is also inseparable from the chip.
The production process of the chip is extremely complex and can be compared to the process of turning point sand into gold. From sand to crystalThe circle, and then to the final chip, its value density increases significantly. Wafers are silicon wafers that make silicon semiconductor integrated circuits, so named because of their circular shape. Wafer to chip value conversion is very significant, a value of 2,000 yuan of wafer raw materials, after processing, its finished value can reach 50,000 yuan, equivalent to the price of a high-performance computer.
