With the continuous improvement of chip technology, there can be over 10 billion transistors in a chip. How are so many transistors installed? 01 As chips are constantly magnified, they resemble a huge city. This is a top-down view SEM photo, which clearly shows the layered structure inside the CPU. The line widths become narrower … Read more
Source: Content from Liu Yishou on Finance, thank you! The global technology war has already begun, with every country striving to excel. The US Secretary of Commerce has revealed that the US has developed two strategic responses to competition from China in the chip sector: one is an offensive strategy, and the other is a … Read more
The global semiconductor industry is currently in a new round of upward economic cycle. The domestic semiconductor industry is influenced not only by global cycles but also by a very strong logic of domestic substitution. Although China has become the largest semiconductor consumer in the world, the self-sufficiency rate of chips is low, with only … Read more
On September 12, 1958, Jack Kilby from Texas Instruments successfully integrated five components, including germanium transistors, to create the world’s first germanium integrated circuit. The following July, Robert Norton Noyce from Fairchild Semiconductor invented the world’s first silicon integrated circuit based on silicon planar technology. Jack Kilby (left) and Robert Noyce (right) As we all … Read more
Source: Lao Qian and His FriendsOriginal Author: Sun Qian This article introduces the fundamentals of integrated circuits from atomic structure to transistors. In the late 19th century, consumer products included simple circuits for lighting, heating, telephones, and telegraphs. However, the invention of radio and the demand for electrical components that could rectify and amplify signals … Read more
01 Introduction This article discusses the current level of FPGA development in China, the companies that are doing well, and the factors to consider for domestic FPGA alternatives. Some content and data are referenced from the internet and official websites. If there are inaccuracies, I hope to discuss and learn from experts. FPGA, The Universal … Read more
Source: Chip Theory Introduction: The first part briefly described the discovery, understanding, and research of semiconductors over a period of 114 years, starting 188 years ago. It also outlined major inventions such as vacuum tubes, transistors, integrated circuits, silicon planar processing technology centered around photolithography, CMOS circuits, non-volatile memory, and single-transistor DRAM. In the more … Read more
// The NIST Multi-TRL calibration technology in the United States implements precise calibration tests of on-chip scattering parameters (S parameters), but this calibration technology has not yet been realized domestically, resulting in the inaccuracy of on-chip measurements not meeting the requirements for precision testing. Based on a thorough study of the Multi-TRL algorithm and independently … Read more
