A closure for a container having an opening includes a base cap and an overcap that form a sealed chamber adjacent the opening that is isolated from the contents of the container. The user interface may comprise a first axis describing a desired level of involvement of the user in investment decisions and a second axis describing a risk tolerance of the user. In exemplary embodiments, the identified objects are displayed in response to selection of a graphical user interface element enabling indication of a second object from among the one or more objects, wherein the first object is associated with the second object in the database after receiving indication of the second object. The solder mask covers over the base rings and extends a short distance into each insertion hole, thereby increasing a creepage distance between conductive layer coatings of adjacent holes. The combination of the deeper nitrogen distribution of the first nitrogen doping process and the shallower nitrogen distribution of the second nitrogen doping process produces a flatter total nitrogen distribution profile so that leakage current from electron tunneling through the gate dielectric layer can be reduced.
