An upgrade of the L3 central tracking system, a silicon muvertex detector (SMD), is described. The detector consists of two layers of silicon, each equipped for rφ and z readout with resolution ≈ 6 μm and ≈ 20 μm respectively. The SMD will provide full azimuthal coverage over the polar angular range 22°≤θ≤158°. The total thickness is ≈0.9% of one radiation length.
