Please note that these are all wafers that are very difficult to obtain, and each batch varies. They will not look exactly like the ones in the photos and are shipped randomly. All wafers look very attractive when viewed under the right lighting. Tech arts are becoming more and more popular as home decor as we are entering the era of Cyberpunk. Silicon wafer, the thin slice of crystal semiconductor, such as a material made up from silicon crystal, which is circular in shape. It's used for the fabrication of integrated circuits and, in photovoltaics, to manufacture solar cells. It undergoes many microfabrication processes, such as doping, ion implantation, etching, thin-film deposition of various materials, and photolithographic patterning. In one word, you may say that silicon wafer is through human ingenuity. There's nothing cooler than a wafer frame as wall decor. Using advanced semiconductor photolithography technology, we are now able to create this wafer frame. Perfect gift for tech & computer lovers!! Turn your room into a modern art gallery with this cool tech art frame! Size: 8in (diameter) Note: Since the silicon crystal we can source each time can vary, there are different kinds of final looks of the wafer frame (as shown in pictures). The look will be subject to shipment, and it will be randomly selected.
