semi conductor wafer
Semi conductor wafer : When discussing the cornerstones of integrated circuits, we have to mention semiconductor wafers, a key material that comes from the careful preparation of high-purity silicon, which is molded through an elaborate process.
It is presented as a round wafer with a variety of diameters and thicknesses, providing unlimited possibilities for the creation of a wide range of electronic devices.

Deep into the journey of semiconductor wafer manufacturing, we first witness the miracle of silicon purification and single-crystal growth, a process that transforms ordinary sand into pure single-crystal silicon rods, laying a solid foundation for subsequent steps.
Next, the grinding and polishing processes give the wafers an extreme surface finish, as smooth as a mirror, creating the ideal conditions for accurate circuit patterning. Cleaning steps follow, ensuring that the wafer surface is spotless and paving the way for subsequent processing.
Oxidation and deposition technologies then intervene to create the insulating and conducting layers on the wafer that form the basis for the circuit.
The subtle use of photolithography, however, opens the way for the fine shaping of circuit structures by precisely transferring complex circuit patterns to the photoresist through a photomask.
