🖥️ iAtlas OLED & Display #1 | 💡 Fundamentals → What Is OLED? At a Glance Introduction OLED has become one of the most important display technologies used in smartphones, televisions, wearables, automotive displays, and emerging AR/VR devices. Unlike LCDs, which require a separate backlight, OLED displays can generate light directly from individual pixels. This…
💻 iAtlas Semiconductor #10 | 📘 Manufacturing → Inspection & Metrology Introduction Modern semiconductor manufacturing requires billions of microscopic structures to be fabricated with extraordinary precision. A tiny particle, a pattern shifted by only a few nanometers, or a film that is slightly too thick can affect device performance or cause a chip to fail….
🔋 iAtlas Battery #32 | 🏢 Companies → LG Energy Solution LG Energy Solution is one of the major companies shaping the global lithium-ion battery industry. Its battery business extends across electric vehicles, energy storage systems, IT devices, light electric vehicles, and emerging applications such as robotics and future mobility. The company also operates across…
💻 iAtlas Semiconductor #9 | 📘 Manufacturing → CMP Introduction Chemical Mechanical Planarization (CMP) creates the extremely flat wafer surfaces required to manufacture modern semiconductor devices layer by layer. Semiconductor fabrication repeatedly adds, patterns, etches, and modifies materials on a silicon wafer. Each process can create small height differences across the surface. If these differences…
🔋 iAtlas Battery #31 | 🏢 Companies → CATL When discussing the global lithium-ion battery industry, one company is impossible to ignore: CATL. Contemporary Amperex Technology Co., Limited—better known as CATL—has grown from a Chinese battery manufacturer into one of the most influential companies in the global electric-vehicle and energy-storage industries. Its importance goes beyond…
💻 iAtlas Semiconductor #8 | 📘 Manufacturing → Ion Implantation Introduction Ion implantation modifies the electrical properties of semiconductor materials by introducing precisely controlled amounts of dopant atoms into selected regions of a silicon wafer. A pure silicon crystal alone cannot provide all the electrical characteristics required to build billions of transistors. Engineers must create…
🔋 iAtlas Battery #30 | 🏭 Manufacturing → 📊 Battery Cell Grading Not every lithium-ion battery cell leaving a production line performs exactly the same. Even when cells use the same materials, design, and manufacturing process, small variations can appear in capacity, open circuit voltage, internal resistance, self-discharge, and other characteristics. These differences matter when…
💻 iAtlas Semiconductor #7 | 📘 Manufacturing → Deposition Introduction Thin film deposition builds the microscopic material layers that form modern semiconductor devices. A semiconductor chip is not made by simply carving circuits into a silicon wafer. Instead, manufacturers repeatedly add, pattern, remove, and modify extremely thin layers of materials to create transistors, insulating structures,…
🔋 iAtlas Battery #29 | 🏭 Manufacturing → ⏳ Battery Aging Process A lithium-ion battery does not move directly from formation to final shipment. After the first controlled charge and discharge cycles, newly formed cells typically enter another important manufacturing stage known as battery aging. During aging, battery cells are stored under controlled conditions while…
💻 iAtlas Semiconductor #6 | 📘 Manufacturing → Etching Introduction Plasma etching transforms the patterns created by photolithography into physical structures on a semiconductor wafer. Photolithography determines where a feature should be formed. Etching determines where material should be removed. This distinction is fundamental to semiconductor manufacturing. After a photoresist pattern is created on the…
