Cell phone chips are basically square. Cell phone chips are made from silicon wafers through photolithography, etching and other processes. Silicon wafers are basically round, and the chip specifications and models on each silicon wafer are exactly the same, to cut these chips from the circular platter, square is the best choice, and square is the optimal choice. Other shapes, such as triangles, diamonds, trapezoids, circles, etc. will not only increase the difficulty of cutting, but also cause material waste, so the chip is square.
Cell phone chips are typically square and made mostly of silicon, which is an atomic crystal that does not dissolve in water or niacin and has a metallic sheen to its surface.
In crystal, opal, agate, quartz and so on contain silicon, and the silicon made of chips mainly from quartz sand, silicon into wafers, and then add ions into semiconductors, you can be made into chips, and the whole process requires high precision, technical content is also very high.
