Silicon wafers are the foundation of nearly every semiconductor device—from microprocessors to solar cells. Yet many people don’t realize how long and complex the wafer production process is. In this article, we break down the steps, timing, and factors affecting how long it takes to go from raw silicon to a finished wafer.

Silicon wafers are essential in the semiconductor industry. They serve as the substrate upon which microelectronic devices—like microprocessors, memory, sensors—are built. One question often asked is: why are silicon wafers circular (round) rather than square or another shape?

Silicon wafers are fundamental to modern electronics. From smartphones to sensors, they provide the base (substrate) that makes semiconductor devices, MEMS, power systems, and photonics possible. This article explains what silicon wafers are, their special variants like SOI (Silicon-on-Insulator), and where & how they are used.

Silicon on Insulator (SOI) is a semiconductor substrate technology in which a thin active silicon layer is separated from the bulk silicon substrate by an insulating layer. This structure improves many device-level properties, offering advantages in speed, power consumption, and reliability compared to conventional bulk silicon wafers.

Silicon wafers are the foundation of modern electronics, serving as the base for integrated circuits (ICs), solar cells, and microelectromechanical systems (MEMS). However, even microscopic contaminants—dust, organic residues, or metallic impurities—can ruin a wafer's performance. Thus, cleaning silicon wafers is a critical step in semiconductor manufacturing.

Silicon wafers are the foundation of modern electronics, serving as the substrate for integrated circuits (ICs), solar cells, and other semiconductor devices. While industrial processes typically use precision machines like diamond saws for wafer dicing, manual cutting may be necessary for prototyping, research, or small-scale production.

Silicon wafers are the backbone of modern electronics, serving as the substrate for integrated circuits (ICs), solar cells, and other semiconductor devices. A common question arises: "Is silicon wafer conductive?" The answer isn't a simple yes or no—it depends on the material's purity, doping, and environmental conditions.

As a leading manufacturer of silicon wafers for semiconductor, photovoltaic, and MEMS applications, we often encounter the question: Are silicon wafers hydrophobic or hydrophilic? The answer is nuanced and depends on the wafer’s surface chemistry, preparation methods, and environmental conditions.

As a manufacturer of silicon wafers, we're often asked about the fascinating process that transforms raw sand into the ultra-pure, mirror-like discs powering all modern electronics. Here's an in-depth look at how we create the foundation of the semiconductor industry.

During the annealing process of optical glass, the inevitable temperature difference between the center and the edge generates stress, also known as residual stress. Stress causes the glass to change from isotropic to anisotropic and produce birefringence.

​What is the Young's modulus? The ratio of the normal stress to the corresponding normal strain in the elastic deformation stage of the material. In the elastic deformation stage of the material, its stress and strain are in direct proportional relationship (that is, it conforms to Hooke's law), and its proportionality coefficient is called the Young's modulus. "Young's modulus" is a physical quantity that describes the elasticity of a material.

​The word epitaxy comes from the Greek word "epi", which means "on top of...". From this word origin, we can easily understand the common expression "GaN on Si", which is the structure of gallium nitride on a silicon substrate. In the preparation process of semiconductor materials, wafer preparation is a core link, which mainly includes two key steps: substrate preparation and epitaxy process.
