    摘要: A method of making a split gate non-volatile memory (NVM) includes forming a charge storage layer on the substrate, depositing a first conductive layer, and depositing a capping layer. These layers are patterned to form a control gate stack. A second conductive layer is deposited over the substrate and is patterned to leave a first portion of the second conductive layer over a portion of the control gate stack and adjacent to a first side of the control gate stack. The first portion of the second conductive layer and the control gate stack are planarized to leave a dummy select gate from the first portion of the second conductive layer, where a top surface of a remaining portion of the first conductive layer is lower relative to a top surface of the dummy select gate. The dummy select gate is replaced with a select gate including metal.

    摘要: A method of making a semiconductor structure uses a substrate having a background doping of a first type. A gate structure has a gate dielectric on the substrate and a select gate layer on the gate dielectric. Implanting is performed into a first portion of the substrate adjacent to a first end with dopants of a second type. The implanting is prior to any dopants being implanted into the background doping of the first portion which becomes a first doped region of the second type. An NVM gate structure has a select gate, a storage layer having a first portion over the first doped region, and a control gate over the storage layer. Implanting at a non-vertical angle with dopants of the first type forms a deep doped region under the select gate. Implanting with dopants of the second type forms a source/drain extension.
