Actually, last I heard Intel had outsourced the actual assembly of their chips to places like Malaysia with low labour costs because that's still not entirely automated. The only thing that they do in high-labour-cost countries is patterning and doping the wafers to create the silicon die inside the chips. That's both a lot easier to automate than sewing (no moving parts) and a lot more important to automate because, due to the small scale, they need to keep out contamination by dust which is a lot easier if few humans are involved.
