A joint connector has a housing with cavities capable of accommodating mating terminals and a joint terminal with a strip-like base and terminal portions projecting at specified intervals from the strip-like base. The system includes a tool and at least one regulator bag disposed adjacent to the tool. A second implant is performed at locations in the well in which transistors of the first subset will be formed and not at locations in the well in which transistors of the second subset will be formed.
