  With the poor global economic conditions and slowing demand for PCs and smartphones, Samsung, Micron and SK Hynix have suffered serious setbacks in their performance. Let's see how these giants turned around beautifully under the cold winter economy.     Samsung Ramped up factory construction and stable cooperation   Samsung has been the dominant player in the global NAND market and was able to account for 43.6% of the NAND market, but this year, Samsung DRAMD's Q3 revenue was $7.4 billion, down 34% sequentially.   Although storage revenue is not optimistic, but recently, Samsung's foundry side of the revenue of $5.58 billion, for the first time more than the main flash business NAND Flash flash memory business revenue of $4.3 billion, it can be seen that Samsung is making great efforts to fill the gap in the performance of the flash memory market, in order to maintain competitiveness, wafers and flash memory always have to be the top pillar of the business.   Samsung has

From a professional point of view, the production process of a chip is extremely complicated and tedious. But in terms of the complete IC industry chain, it is mainly divided into four parts: IC design → IC manufacturing → packaging → testing.   Chip fabrication process.   I. Chip design   Chip belongs to the small size, but great high precision products. To make a chip, design is the first link. The design needs to be done with the help of EDA tools and some IP cores, and finally made into the chip design blueprint needed for processing.   II . sand-silicon separation   All semiconductor processes start with a grain of sand. Because the silicon contained in the sand is the raw material needed to produce the silicon wafer, the "foundation" of the chip. So our first step is to separate the silicon from the sand.     III . silicon purification   After the silicon is separated out, the rest of the material is discarded. The silicon is purified in several steps to achieve the qua

  Artificial intelligence chips mainly include NVidia GPU, Google's TPU, Intel's Nervana, IBM's TreueNorth, Microsoft's DPU and BrainWave, Baidu's XPU, Xilinx's xDNN, Cambrian chip, Horizon and Deepview's AI chip, etc. Basically, GPU, FPGA, and neural network chips are the three major trends. The three chips have their own advantages and disadvantages and are all geared toward their own unique market segments. This chapter first talks about the rise of deep neural networks and NVidia GPUs.   The ultimate goal of artificial intelligence is to simulate the human brain, which has roughly 100 billion neurons and 100 trillion synapses, capable of handling complex vision, hearing, smell, taste, language skills, comprehension, cognitive abilities, emotional control, control of complex body mechanisms, complex psychological and physiological control while consuming only 10 to 20 watts of power.   These are the basic neurons and synapses of the human brain.     The i

  What are the constituent materials of the chip?   Silicon is mainly refined from quartz sand, wafers are silicon elements to be purified (99.999%), followed by the pure silicon made of silicon wafers, which become the material for the manufacture of integrated circuits quartz semiconductor, will be sliced is the chip production specific wafers required. The thinner the wafer, the lower the cost of production, but the higher the requirements of the process.   Some people may ask, there are so many semiconductors, why would choose silicon to produce chips? In fact, the main reasons for choosing silicon as the raw material for chips are the following ：   1.  Silicon is the second most abundant element on earth, it is easy to find the raw material for purification, and silicon-related treatment process has been developed for decades, which is very mature compared to other elements.   2.  Silicon is cheap and easy to promote.   3. S ilicon is chemically stable, so the stability of the man

If you look at a modern printed circuit board (PCB), you will almost certainly see at least two or three rectangular black packages with silver terminals protruding from the edges. For example   Electrical engineers often refer to these packages as components or devices, and for good reason - they look like components, are purchased as components, and often act as components. But if we interpret the term to mean things like resistors, capacitors, inductors, diodes and transistors, engineers will know that they are not actually components. Instead, these black packages are actually circuits.   What is an integrated circuit? A very valuable property of transistors is that they can be very small, which in turn allows us to compress complex functions into a very small physical area. However, a microscopic transistor is not very useful in the macroscopic world: how do we plug it into a breadboard or measure its voltage? How does the assembler place it on the PCB?   The creation of integrate

  A   transistor   is a semiconductor device that switches on and off and amplifies electronic signals. It has at least three terminals that connect it to electronic circuits. The transistor was invented in the early 1950s and quickly replaced vacuum tubes in electronic devices. These devices are now an important part of almost all electronic devices, such as the central processing unit   (CPU)   of computers. A CPU transistor is usually part of an integrated circuit, although it can also be purchased separately.   A central processing unit (CPU). Terminals in CPU transistors have specific names, depending on the type of transistor. The terminals of a simple bipolar transistor are called the collector, emitter, and base. The current or voltage applied to the base affects the flow of current from the collector to the emitter.     The voltage at the base of the transistor can be used to turn on and off the current flowing from the collector to the emitter. This type of transistor is a s

  Chip   Chip, also known as microcircuit, microchip, or integrated circuit (English: integrated circuit, IC). It is a silicon chip containing an integrated circuit, which is very small and often part of a computer or other electronic device.   Chip, English for Chip; chipset for Chipset. chip generally refers to the carrier of the integrated circuit, but also the integrated circuit after design, manufacturing, packaging, testing, usually an independent whole that can be used immediately. The two words "chip" and "integrated circuit" are often used together, for example, in the usual discussion topics, integrated circuit design and chip design is said to mean one thing, chip industry, integrated circuit industry, IC industry, IC industry is often a meaning. In fact, these two terms have a connection and a difference. Integrated circuit entities often have to exist in the form of chips, because the narrow sense of integrated circuit, is to emphasize the circuit itsel
