Abstract
The present invention is a flexible circuit electrode array for improved layer adhesions where the metal conductors overlap the polymer insulator. The steps to build the flexible circuit are as follows. Deposit a base polymer layer. Deposit a conductive trace over the base polymer layer. Deposit a top polymer layer over the trace and prepare a void in the top polymer layer smaller than the surface of the trace. Deposit an electrode on the trace through the void with a periphery larger than, and overlapping the void.
Claims16
A flexible circuit electrode array comprising:
- a base polymer layer;
- a conductive trace deposited on the base polymer layer;
- a top polymer layer deposited on the base polymer layer and the trace, and defining a void;
- the trace forming an electrode base extending peripherally beyond the void;
- and
- an electrode connected to the electrode base through the void and extending peripherally beyond the void.
