    Abstract: Aspects disclosed in the detailed description include high-k (HK)/metal gate (MG) (HK/MG) multi-time programmable (MTP) switching devices, and related systems and methods. One type of HK/MG MTP switching device is an MTP metal-oxide semiconductor (MOS) field-effect transistor (MOSFET). When the MTP MOSFET is programmed, a charge trap may build up in the MTP MOSFET due to a switching electrical current induced by a switching voltage. The charge trap reduces the switching window and endurance of the MTP MOSFET, thus reducing reliability in accessing the information stored in the MTP MOSFET. In this regard, an HK/MG MTP switching device comprising the MTP MOSFET is configured to eliminate the switching electrical current when the MTP MOSFET is programmed. By eliminating the switching electrical current, it is possible to avoid a charge trap in the MTP MOSFET, thus restoring the switching window and endurance of the MTP MOSFET for reliable information access.

    Abstract: A method for removing a doped amorphous carbon mask from a semiconductor substrate is disclosed. The method comprises generating a plasma to be used in treating the substrate, wherein the plasma comprises an oxygen containing gas, a halogen containing gas, and a hydrogen containing gas; and treating the substrate by exposing the substrate to the plasma. The doped amorphous carbon mask can be a boron doped amorphous carbon mask or a nitrogen doped amorphous carbon mask. The method can result in a mask removal rate ranging from about 1,000 ngstrms/minute to about 12,000 ngstrms/minute. Further, gases can be applied to the substrate before plasma treatment, after plasma treatment, or both to reduce the amount of defects or pinholes found in the substrate film.

    Abstract: In a system having a memory device, an event is detected during system operation. The memory device is heated to reverse use-incurred degradation of the memory device in response to detecting the event. Tn another system, the memory device is heated to reverse use incurred, degradation concurrently with execution of a data access operation within another memory device of the system. In another system having a memory controller coupled to first and second memory devices, data is evacuated from the first memory device to the second memory device in response to determining that a maintenance operation is needed within the first memory device.
