I work for a fabless company, and we have taped out several chips before, so I'm familiar with the overall flow from design -> manufacturing. Some of the design-service companies offer "turnkey service"? What exactly does that mean? When I read the description, I get the impression that the design-service handles wafer-cutting, packaging, and test(ATPG.) Basically, they manage this so the fabless customer doesn't need to contact individual specialist companies. Is that right? Or is there something more?
