  • Patent number: 12262642
    Abstract: A method for fabricating magnetoresistive random-access memory cells (MRAM) on a substrate is provided. The substrate is formed with a magnetic tunneling junction (MTJ) layer thereon. When the MTJ layer is etched to form the MRAM cells, there may be metal components deposited on a surface of the MRAM cells and between the MRAM cells. The metal components are then removed by chemical reaction. However, the removal of the metal components may form extra substances on the substrate. A further etching process is then performed to remove the extra substances by physical etching.

The robotic manipulator corresponds to a robotic manipulator coordinate. The calibrating image is disposed on the robotic manipulator. The camera corresponds to a camera coordinate and for shooting the target object and generating a picture. The processor is configured to move the robotic manipulator such that the calibrating image moves towards the target object and enters the picture. The processor records robotic manipulator coordinate datasets and camera coordinate datasets of the calibrating image as the calibrating image moving towards the target object, and uses the robotic manipulator coordinate datasets and the camera coordinate datasets to execute a hand-eye calibrating algorithm to obtain a calibrated mapping between the camera coordinate and the robotic manipulator coordinate.
