Ingot to wafer
Did you know?
WebbGrowing a silicon ingot can take anywhere from one week to one month, depending on many factors, including size, quality, and the specification. Let’s take a deeper look at silicon wafer processing and how exactly they are made. Ingot Growth. To grow an ingot, the first step is to heat the silicon to 1420°C, above the melting point of silicon. WebbOnce the ingot is fully-grown, it is ground to a rough size diameter that is slightly larger than the target diameter of the final silicon wafer. The ingot has a notch or flat cut into …

WebbJapanese Patent Laid-Open No. 5-185419. When the warpage shape of the wafer (ingot) feeding direction of the wafer obtained by cutting the ingot with the wire saw 101 as described above is confirmed, it becomes a convex wafer or a concave shape depending on the position in the ingot. There are mixed wafers. WebbWe produce small-diameter silicon wafers (12 inches or less) for semiconductors in an integrated manner ranging from single crystal ingots to wafer processing. We have established the global supply system mainly for the mass-produced wafers for bipolar integrated circuits, discrete circuits, and MEMS. Map of the silicon wafer factories in China
WebbWafer production places high demands on the technology used, while the market demands maximum efficiency from manufacturers. The new, environmentally friendly diamond wire technology for wire saws doubles the cutting speed of saws. Siemens offers optimized automation concepts for high-performance ingot cutting machines.
