Abstract:
A method of making a capacitor structure, comprising the steps of:forming a generally L-shaped non-conductor on a dielectric underlying layer, including the steps offorming a disposable plug on the underlying layer, the disposable plug having a substantially horizontal surface and at least one substantially vertical surface,forming a layer of non-conductive material over the disposable plug, the layer of non-conductive material having a first horizontal portion on the underlying layer, a second horizontal portion on the horizontal surface of the disposable plug and a vertical portion with a substantially uniform thickness on the substantially vertical surface of the disposable plug,forming a layer of planarizable material on the layer of non-conductive material, the layer of planarizable material covering the second horizontal portion of the non-conductive layer,planarizing the layer of planarizable material to expose the second horizontal portion of the non-conductive layer, andremoving the disposable plug,the generally L-shaped non-conductor having a horizontal portion and a vertical portion, the vertical portion having a first opening formed in said vertical portion, thereby defining an exposed portion of the underlying layer;forming a generally U-shaped conductor within the first opening and covering said exposed portion of the underlying layer; andforming a generally L-shaped conductor exterior to the generally L-shaped non-conductor.
