Then the metal on the chip is electroplated.
2, the process of manufacturing a chip, in essence, is the process of realizing a transistor on a silicon material. The transistors in a chip can be abstracted into the following pattern: the transistors in the chip are on top of the silicon crystal, which needs to have a silica insulation layer and a conductive silicon compound layer (red in the image) on top of it, which acts as a switch.
3, the production process of the chip generally includes semiconductor material preparation, wafer preparation, lithography technology, etching technology, cleaning and detection; The principle is based on the semiconductor properties of grass electronsLearn the theory. 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.
What does it mean to make a chip? In the field of modern science and technology, the chip is a key component. Chips, also known as integrated circuits, are the core components of electronic and computer systems used to store and process data. The process of manufacturing chips is very complex and requires advanced technology and equipment. The following will talk about the manufacturing process of chips from three aspects: process flow, basic materials and uses. First of all, the manufacturing of chips requires a multi-layer process.
ForThe process of making chips can be a bit of a mystery to beginners. In fact, making a chip refers to the process of converting a wafer (silicon wafer) into an electronic chip. In this process, various materials and equipment need to be used, such as lithography machines, ion implantation machines, chemical evaporators, etc. In the process of making chips, companies like Intel need to process silicon wafers with precision to build tiny transistors, wires and capacitors on their surfaces.
Chip is a general term for semiconductor components. It usually refers to the tiny silicon chips containing integrated circuits. This silicon chip is small and is a key component of computers and other electronic devicesPoints. As the carrier of an integrated circuit (IC), a chip is composed of individual silicon wafers split from a wafer. These silicon chips are rich in integrated circuits, the core elements that make up computers and other electronic devices.
A chip is an electronic component that is manufactured by microelectronics technology and integrates circuits and systems on a tiny silicon chip. Chip includes transistors, resistors, capacitors and other electronic components, is one of the core components of various electronic devices. Chip manufacturing requires high-precision, high-purity materials and complex process flow, which is an important part of modern science and technology. A chip is an integrated circuit consisting of a large number ofTransistor construction.
Usually referred to as "chip" refers to the integrated circuit, it is the main product of microelectronics technology. The so-called microelectronics is relative to the concept of strong electricity, weak electricity ', which means that the electronic signal it processes is extremely small. It is the basis of modern information technology, we usually contact with electronic products, including communications, computers, intelligent systems, automatic control, space technology, radio, television, etc., are developed on the basis of microelectronics technology.
The precision of the chip its manufactureThe manufacturing process is very complex. First, the chip design, according to the design needs, the generated "pattern" 1, the raw material of the chip wafer wafer composition is silicon, silicon is refined by quartz sand, the wafer is the silicon element to be purified (9999%), and then some pure silicon into silicon rod, become the quartz semiconductor material for manufacturing integrated circuits. Slicing it is the wafer that is specifically needed for chip production. On September 12, Jack Kilby (1923-2005), an electronics engineer at Texas Instruments, invented the integrated circuit and successfully manufactured the world's first one in 1959Integrated circuit, that is, chip. The integrated circuit is to etch out PNP transistors (triode), resistors and capacitors on a germanium sheet, and connect them into a circuit with external wires.
The entire chip manufacturing process is divided into many small steps. First, the wafer is put into a Furnace at a temperature of 1000 ° C, which is designed to oxidize the wafer surface to form a silica insulation layer. Wafers are oxidized in a heating furnace and then photoresist is applied to the surface of the wafers in preparation for wafer exposure.
From 1949 to 1957, VilleNa Jacoby, Jeffrey Dummer, Sidney Darlington, and Yasuo Tarui all developed prototypes, but the modern integrated circuit was invented by Jack Kilby in 1958. He won the Nobel Prize in Physics in 2000, but Robert Noyce, who also developed the modern practical integrated circuit at the same time, died earlier than 1990.
Raw materials for single Wafer: The raw materials for chip production are mainly Silicon wafers, which are a round sheet of high-purity silicon. Lithography: The circuit pattern to be made is exposed and retouched on the silicon wafer with special equipmentPhotolithography, or color photography, is then chemically formed into patterns. This process needs to be repeated many times, gradually forming a complex circuit pattern.
