The process of manufacturing a chip usually takes anywhere from a few weeks to a few months, depending on a number of factors, such as the complexity of the chip, the manufacturing process, the equipment used, the amount of work and the production capacity. Highly complex chip manufacturing can take longer, while more advanced process technology can shorten the manufacturing cycle.
Raw material supply chains, design validation and testing need to be considered, which can also affect manufacturing time.
Look at the wafer manufacturing process, generally 1 month to 3 months
