Yes, TSMC makes the chips for iPhones, as well as Snapdragon processors used by many (but not all) high-end Android phones. Samsung has their own factory in South Korea, and Huawei has theirs in mainland China. Further, low-end smartphones and most dumbphones use Unisoc chips that are made in China.
As for desktop computers, Intel has factories in the US, and AMD (GlobalFoundries) in Germany and Singapore.
