Claim Text:
1. A method for manufacturing a portable data carrier having the method steps of: making available a carrier band having an upper side and a lower side disposed opposite the upper side, wherein on the upper side a contact field is formed having at least one contact area; arranging a semiconductor circuit on the lower side of the carrier band, wherein the semiconductor circuit is electroconductively connected with the corresponding contact area; and executing a top gated injection molding process in that on the lower side a first potting compound is formed around the semiconductor circuit, wherein said first potting compound has the outer dimensions in accordance with a predetermined specification of a portable data carrier, wherein the semiconductor circuit is encapsulated by a second potting compound before the injection molding process and wherein the first potting compound has improved flow properties from the second potting compound that provides ease in forming a depression and achieving a smaller corner radius and a steeper flank angle, wherein after the injection of the potting compound a depression remains in the finished data carrier and is centered on a lower side of the data carrier body.
