摘要： Embodiments herein provide relatively permanent labeling of an imprint lithography template. The imprint lithography template generally has first and second sides, one side having a pattern to imprint a substrate and the other being optically smooth to unobstructably pass UV light. In one embodiment, a method of labeling the imprint lithography template includes placing a masking layer on a portion of the first side (e.g., the optically smooth side) of the template, forming a liftoff layer on the remainder of the first side of the template, removing the masking layer to expose the portion of the first side of the template, and placing a polymer mark on the exposed portion of the first side of the template. The method also includes depositing an opaque material on the first side of the template and removing the liftoff layer and the mark to form a label on the first side of the template with the deposited opaque material.

摘要： A magnetic write head for perpendicular magnetic recording. The write head has a secondary flare point defined by magnetic structures that extend from the sides of the write pole, but not over the trailing edge of the write pole. The magnetic structures each have a front edge that defines the secondary flare point. By constructing the magnetic structures so that they only extend from the sides of the write pole and not over the write pole, they can be formed by electroplating, while leafing the mask structure (used to define the write pole) still intact, thereby greatly simplifying manufacture and preventing damage to the write pole during manufacture.
摘要翻译：用于垂直磁记录的磁写头。写头具有由磁性结构限定的次级耀斑，其从写入极的侧面延伸，但不在写入极的后缘上方。磁性结构各自具有限定次级耀斑点的前边缘。通过构造磁结构，使得它们仅从写入极的侧面延伸而不是在写入极之上，它们可以通过电镀形成，同时使掩模结构（用于定义写入极）仍然完整，从而大大简化在制造过程中制造和防止对写入极的损坏。

摘要： A magnetic structure, such as a pole tip, and method for forming the same includes forming a pole tip layer of magnetic material. A layer of polyimide precursor material is added above the pole tip layer and cured. A silicon-containing resist layer is added above the layer of polyimide precursor material and patterned. The resist layer is exposed to oxygen plasma for converting the resist into a glass-like material. Exposed portions of the cured polyimide precursor material are removed for exposing portions of the pole tip layer. The exposed portions of the pole tip layer are removed for forming a pole tip. Chemical mechanical polishing (CMP) can then be performed to remove any unwanted material remaining above the pole tip.

摘要： In one illustrative example, a three terminal magnetic sensor (TTM) has a sensor stack structure which includes a base region, a collector region, and an emitter region. A first barrier layer is located between the emitter region and the base region, and a second barrier layer is located between the collector region and the base region. A plurality of terminals of the TTM include a base lead coupled to the base region, a collector lead coupled to the collector region, and an emitter lead coupled to the emitter region. The collector region is or includes a layer of semiconductor material. The base region includes a free layer structure. The TTM further includes a self-pinned layer structure and an in-stack longitudinal biasing layer (LBL) structure formed in stack with the sensor stack structure, with a magnetic moment that is parallel to a sensing plane of the TTM for magnetically biasing the free layer structure.
