Abstract: A first trench sidewall has a continuous first taper angle that terminates at a first plane. At least one layer may be deposited that forms a second trench sidewall with a continuous second taper angle that extends a predetermined depth past the first plane and is less than the first taper angle. A write pole may then be formed on the second trench sidewall with the write pole being closer to the first trench sidewall at the predetermined depth than at the first plane.
Abstract translation: 第一沟槽侧壁具有在第一平面处终止的连续的第一锥角。 可以沉积至少一层，其形成具有延伸预定深度超过第一平面并且小于第一锥角的连续第二锥角的第二沟槽侧壁。 然后可以在第二沟槽侧壁上形成写入极，而写入极比预定的深度比第一平面更靠近第一沟槽侧壁。
