The semiconductor industry is a key cornerstone of the modern information society. With the accelerated evolution of new technological changes such as artificial intelligence and the Internet, the development of the electronic information industry has entered a new round of upgrading and transformation. The demand for the semiconductor market is also growing. The global semiconductor industry has bucked the trend and increased by 6.5%. China is the world's largest semiconductor market.
A wafer is a thin slice of semiconductor material used to fabricate integrated circuits or other microdevices1. Also called a slice or substrate, wafers must undergo a number of steps in the preparation process before they are ready for use.
Manufacturing processes for silicon semiconductor
Silicon Ingot ⇒ Cropping(electroplated bandsaw) ⇒ Cylindrical / Flat Grinding Silicon Rod ⇒ Ingot Silicon (diamond wire) ⇒ Lapping (double side wheel/polishing pad) ⇒ Edge Grinding ⇒ Surface grinding ⇒ polishing⇒ wafer⇒ patterning ⇒ back grinding (vitrified / resin wheels) ⇒ dicing (dicing blades)⇒ chips ⇒ molding ⇒ packaging
