Abstract:
1. A method for contacting an electrically conductive layer overlying a magnetoelectronics element in an array of magnetoelectronics elements, the method comprising the steps of: forming an array of magnetoelectronics elements on a dielectric region, said magnetoelectronics elements having electrically conductive layers formed thereon; depositing a conformal first dielectric layer overlying said array of magnetoelectronics elements and said dielectric region; depositing an etch stop layer overlying said first dielectric layer; depositing a second dielectric layer overlying said etch stop layer; patterning said second dielectric layer and etching a portion of said second dielectric layer to form a contiguous exposed portion of said etch stop layer overlying said array of magnetoelectronics elements; and removing said exposed portion of said etch stop layer and a portion of said first dielectric layer to expose said electrically conductive layers.
