Abstract
A seek-scan probe (SSP) memory including a recess cavity to self-align magnets includes a frame, a movable platform movably coupled to the frame, a coil coupled to the movable platform, and a cap wafer having coupled to the frame. The cap wafer includes a recess cavity to receive a magnet that produces a magnetic field. By energizing the coil while in the magnetic field a physical force is produced that is translated into movement of the movable platform.
Claims24
An apparatus comprising:
- a movable platform movably coupled to a frame;
- an electrically conductive coil coupled to the movable platform;
- and
- a cap wafer coupled to the frame and including therein a recess cavity configured to receive a magnet and positioned such that the electrically conductive coil will be subject to a magnetic field of the magnet when the magnet is placed in the recess cavity.
