    摘要: A magnetic tunnel junction element is provided. The magnetic tunnel junction element has first magnetic layer and second magnetic layer formed adjacent, e.g., on lower and upper portions of an insulating layer, respectively and each having a perpendicular magnetic anisotropy, a magnetic field adjustment layer formed on the second magnetic layer and having a perpendicular magnetic anisotropy, and a bather layer formed between the magnetic field adjustment layer and the second magnetic layer. The second magnetic layer and the magnetic field adjustment layer are magnetically decoupled from each other.

    摘要: A test pattern and a method of controlling a CMP using the same are provided. The test pattern is disposed on a monitoring region of a semiconductor substrate having a main region and a monitoring region. The test pattern includes a planar region and a pattern region. The method comprises setting a correlation between a step difference of a test pattern and an etched thickness of a main pattern, then applying the CMP to a semiconductor substrate having the test pattern and the main pattern for a predetermined time. The step difference of the test pattern is measured and the etched thickness of the main pattern, which corresponds to the step difference of the test pattern, is determined from the correlation. A polishing time is corrected by comparing the determined etched thickness of the main pattern with a reference value, and the corrected polishing time is applied to a subsequent lot or subsequent substrate.

    摘要: Methods of forming ferroelectric layers include forming a ferroelectric layer on a substrate and chemically-mechanically polishing a surface of the ferroelectric layer by rotating a polishing pad on the surface at a rotation speed in a range from about 5 rpm to about 25 rpm. This polishing step includes pressing the polishing pad onto the surface of the ferroelectric layer at a pressure in a range from about 0.5 psi to about 3 psi. This polishing step may be followed by the step of exposing the polished surface to a rapid thermal anneal. This anneal can be performed in an inert atmosphere containing a gas selected from a group consisting of nitrogen, helium, argon and neon.
