    Top Semiconductor Suppliers Extend Their Lead

    The international semiconductor research firm IC Insights has released its latest industry monitoring report. It notes that, driven by the sustained explosion in AI computing demand, the global semiconductor market is concentrating rapidly among leading companies, the Matthew effect is further amplified, top semiconductor suppliers are gradually forming an oligopolistic structure, the top ten companies hold nearly 70% of market share, and the survival space of small and mid-sized manufacturers keeps shrinking.Report data shows that in 2025 the global semiconductor market reached USD 831 billion in total size, and the ten highest-revenue semiconductor companies posted combined revenue of USD 562.1 billion — a market share of 67.6%. The growth data clearly shows divergence: over 2023–2025 the industry as a whole grew revenue by 53%, while the top ten vendors grew by as much as 90%, and all other small and mid-sized vendors combined grew only 8% — nearly all of the growth dividend flo...

  • Six Non-Ferrous Metals: Properties and Uses

    Six Non-Ferrous Metals: Properties and Uses

    Copper (Cu) Copper is a purplish-red heavy metal whose electrical and thermal conductivity are second only to silver. It has excellent ductility, corrosion resistance and weldability, can be recycled indefinitely, and is the core metal of the power industry (Source: Copper Development Association). Its main ores are chalcopyrite and bornite. Its largest consumption sector is power: wire and cable, transformers, busbars, high-voltage wiring harnesses of new-energy vehicles, PV inverters and energy-storage converters. Next come air-conditioning and refrigeration copper tube, plumbing pipe, and copper alloys (brass and bronze) for valves, bearings and marine fittings. The electronics industry uses it for PCBs, connectors and chip heat-spreading substrates. Copper is also a key material of the energy transition — wind power, PV and new-energy vehicles all drive copper demand sharply upward, earning it the name "energy metal". Aluminium (Al) Aluminium is a silvery-w...

    Chips, Semiconductors and Integrated Circuits

    What is the difference between chips, semiconductors and integrated circuits? Most people who know hardware well are fairly clear about this question. Let's go through the analysis of several contributors to get familiar with it again. 01 The first answer comes from Zhihu contributor: Hetzer Manning Semiconductor is the general term for a class of materials; an integrated circuit is a large collection of circuits made from semiconductor materials; a chip is a product formed from one or various types of integrated circuits. Put into everyday objects everyone understands: the various fibres used to make paper are semiconductor materials, a stack of paper is an integrated circuit, and the book or notebook is the chip. The improvements the industry is currently striving for fall into three types: 1. Finding new fibres to make better reading media. 2. Using existing papermaking technology to make paper cheaper and cheaper, whiter and whiter, thinner and thinne...

  • Germanium: the Most Futuristic Metal

    Germanium: the Most Futuristic Metal

    People in the semiconductor world, or those familiar with electronics, have always known that a different semiconductor could replace silicon in transistors and circuits. That alternative is an element called germanium (Ge). Germanium is a metal with a futuristic feel — see for yourself below. Germanium is a brittle, silvery-white element with semiconductor properties similar to silicon. For years germanium was the first choice for semiconductor electronics and circuits, but it soon became more expensive once silicon was found to serve the same purpose. Because silicon is far more abundant and naturally available in the world, collecting and refining it for conduction purposes was very cheap, so once computers went into mass production and became available to the public, silicon displaced germanium. Germanium ore is actually very rare in nature, which explains its relative cost. Germanium can be obtained from zinc ores and from the dust processed in zinc smelter flues, and of c...

  • Uses and Application Fields of Germanium

    Uses and Application Fields of Germanium

    Germanium is a silvery-grey dispersed metal belonging to group IVA, with excellent semiconductor properties, infrared transparency and optical refractive-index control. Its content in the earth's crust is extremely low and it has almost no independent ore bodies, occurring mostly associated with lead-zinc ores and lignite. It is a critical strategic mineral recognized worldwide, broadly supporting the development of high-end industries such as telecommunications, infrared optoelectronics, aerospace new energy, semiconductors, detection and chemicals (Source: Popular Science China).Fibre-optic communication is one of germanium's most important consumption channels, mainly using germanium tetrachloride and germanium dioxide as dopants for optical fibre preforms. Doping the quartz fibre core with germanium raises the refractive index of the glass, reduces the loss of optical signals over long-distance transmission, and keeps high-speed optical signal transmission stable. As ...
