摘要： Performance and reliability of a semiconductor device including a non-volatile memory are improved. A memory cell of the non-volatile memory includes, over an upper portion of a semiconductor substrate, a select gate electrode formed via a first dielectric film and a memory gate electrode formed via a second dielectric film formed of an ONO multilayered film having a charge storing function. The first dielectric film functions as a gate dielectric film, and includes a third dielectric film made of silicon oxide or silicon oxynitride and a metal-element-containing layer made of a metal oxide or a metal silicate formed between the select gate electrode and the third dielectric film. A semiconductor region positioned under the memory gate electrode and the second dielectric film has a charge density of impurities lower than that of a semiconductor region positioned under the select gate electrode and the first dielectric film.

摘要： A memory cell includes a selective gate and a memory gate arranged on one side surface of the selective gate. The memory gate includes one part formed on one side surface of the selective gate and the other part electrically isolated from the selective gate and a p-well through an ONO layer formed below the memory gate. A sidewall-shaped silicon oxide is formed on side surfaces of the selective gate, and a sidewall-shaped silicon dioxide layer and a silicon dioxide layer are formed on side surfaces of the memory gate. The ONO layer formed below the memory gate is terminated below the silicon oxide, and prevents generation of a low breakdown voltage region in the silicon oxide near an end of the memory gate during deposition of the silicon dioxide layer.
