摘要： Provided are an on-chip balun, a transceiver using the on-chip balun, and a method for fabricating the on-chip balun. The on-chip balun includes: a first metal winding including a port grounded and a port to which an unbalanced signal is input; a second winding outputting an induced current generated by the first metal winding as two signals having about equal intensity and a phase difference of about 180°; and a ground shield positioned between the first and second metal windings and having a symmetric structure so as to generate a symmetric parasitic capacitance between the ground shield and the second metal winding. The ground shield can be inserted between the first and second metal windings to remove an asymmetrical parasitic capacitance so as to reduce a phase imbalance and a gain imbalance of an output value of the second metal winding. As a result, a highly balanced on-chip balun can be fabricated.

摘要： After an insulation layer is formed on a substrate, a contact hole is formed through the insulation layer. A recessed plug is formed to partially fill up the contact hole. The recessed plug has a height substantially smaller than a depth of the contact hole. A metal wiring structure is formed on the recessed plug and on the insulation layer. A lower portion of the metal wiring structure, formed within the contact hole, prevents damage to the recessed plug during an etching process for forming the metal wiring structure. Therefore, the recessed plug may be formed without damage thereof even if an alignment error occurs between an etching mask and the recessed plug during metal wiring structure formation.
