NXP semiconductor said on Tuesday that it has opened a plant in Chandler, Arizona, to produce gallium nitride chips for 5g telecommunications equipment. Gallium nitride is a substitute for silicon. This material is a key component in 5g networks because it can handle the high frequencies used in 5g networks, while consuming less power and space than other chip materials. < / P > < p > according to NXP, the new plant will produce six inch chips, which are half the size of most traditional silicon chips, but are common in alternative materials.
