Abstract: In one example, an apparatus includes a base, a first inductor, and a second inductor. The first inductor is on the base. The first inductor has a first winding extension, a second winding extension, and a first winding coupled between the first winding extension and the second winding extension, in which at least a part of the second winding extension is vertically between at least a part of the first winding extension and the base. Also, the second inductor is on the base. The second inductor has a third winding extension, a fourth winding extension, and a second winding coupled between the third winding extension and the fourth winding extension, in which at least a part of the fourth winding extension is vertically between at least a part of the third winding extension and the base, and the second winding is laterally adjacent to the first winding.

Abstract: A permanent resist, such as TMMF, is used when patterning conductive material on a substrate, enabling lines that have a higher line-to-space ratio (L/S) or a higher aspect ratio (T/L) or both. Pattern density can thus be increased, allowing for improved performance (e.g., greater efficiency, in the case of transformer coil patterning) and greater heat dissipation. As examples, the permanent-resist-based patterning fabrication methods can be used to create transformer coils within an integrated circuit (IC) module, or a routable lead frame for one or more IC dies.
