More particularly, the disclosure discusses a stimulation lead that includes one or more silicon based barrier layers within a MEMS film. The silicon based barrier layers can improve device reliability and durability. The silicon based barrier layers can also improve adhesion between the layers of the MEMS film. ## Claims ### Claim 1 A neurological lead, comprising: an external tube comprising a proximal end and a distal end; a planar formed, cylindrical film coupled with the external tube, the planar formed, cylindrical film comprising: a plurality of tabs distributed longitudinally along the planar formed, cylindrical film; a plurality of ribbon cables, each of the plurality of ribbon cables coupled to two of the plurality of tabs distributed longitudinally along the planar formed, cylindrical film; a plurality of electrodes, at least one of the plurality of electrodes disposed on each of the plurality of tabs distributed longitudinally along the planar formed, cylindrical film; a plurality of periphery traces, each of the plurality of periphery traces at least partially encircling a perimeter of a respective one of the plurality of electrodes; and a plurality of contacts, a respective one of the plurality of contacts disposed on each of the plurality of ribbon cables and between the two of the plurality of tabs distributed longitudinally along the planar formed, cylindrical film. ### Claim 2 (depends on 1) The neurological lead of claim 1, comprising: a plurality of lead wires disposed within the external tube, each of the plurality of lead wires coupled with the respective one of the plurality of contacts disposed on each of the plurality of ribbon cables. ### Claim 3 (depends on 1) The neurological lead of claim 1, comprising: each of the plurality of tabs wrapped around a circumference of the external tube at a different longitudinal location. ### Claim 4 (depends on 1) The neurological lead of claim 1, comprising: a plurality of traces, the respective one of the plurality of contacts disposed on each of the plurality of ribbon cables coupled with a respective one of the plurality of electrodes via a respective one of the plurality of traces. ### Claim 5 (depends on 1) The neurological lead of claim 1, comprising: the plurality of ribbon cables extending into the external tube. ### Claim 6 (depends on 1) The neurological lead of claim 1, comprising: at least two of the plurality of electrodes disposed on each of the plurality of tabs. ### Claim 7 (depends on 1) The neurological lead of claim 1, wherein a width of each of the plurality of ribbon cables is less than a width of each of the plurality of tabs. ### Claim 8 (depends on 1) The neurological lead of claim 1, wherein the external tube comprises a backfilled polymer. ### Claim 9 (depends on 1) The neurological lead of claim 1, wherein the external tube is flexible. ### Claim 10 A method to form a neurological lead, comprising: forming a film comprising: a plurality of tabs distributed longitudinally along the film; a plurality of ribbon cables, each of the plurality of ribbon cables coupled to two of the plurality of tabs distributed longitudinally along the film; a plurality of electrodes, at least one of the plurality of electrodes disposed on each of the plurality of tabs distributed longitudinally along the film; a plurality of periphery traces, each of the plurality of periphery traces at least partially encircling a perimeter of a respective one of the plurality of electrodes; and a plurality of contacts, a respective one of the plurality of contacts disposed on each of the plurality of ribbon cables and between the two of the plurality of tabs distributed longitudinally along the film; heating the film; and molding the film into a cylinder, the cylinder defining a lumen. ### Claim 11 (depends on 10) The method of claim 10, comprising: coupling the film with an external surface of an external tube. ### Claim 12 (depends on 10) The method of claim 10, comprising: backfilling the cylinder with a polymer to form an external tube. ### Claim 13 (depends on 10) The method of claim 10, comprising: disposing a plurality of lead wires within an external tube, each of the plurality of lead wires coupled with the respective one of the plurality of contacts disposed on each of the plurality of ribbon cables. ### Claim 14 (depends on 10) The method of claim 10, comprising: wrapping each of the plurality of tabs around a circumference of an external tube at a different longitudinal location. ### Claim 15 (depends on 10) The method of claim 10, comprising: coupling the respective one of the plurality of contacts disposed on each of the plurality of ribbon cables with a respective one of the plurality of electrodes via a trace. ### Claim 16 (depends on 10) The method of claim 10, comprising: extending the plurality of ribbon cables into an external tube. ### Claim 17 (depends on 10) The method of claim 10, comprising: disposing at least two of the plurality of electrodes on each of the plurality of tabs. ### Claim 18 (depends on 10) The method of claim 10, wherein a width of each of the plurality of ribbon cables is less than a width of each of the plurality of tabs.
