Patent number: 11545583Abstract: An electronic device can include a NVM cell. The NVM cell can include a drain/source region, a source/drain region, a floating gate electrode, a control gate electrode, and a select gate electrode. The NVM cell can be fabricated using a process flow that also forms a power transistor, high-voltage transistors, and low-voltage transistors on the same die. A relatively small size for the NVM can be formed using a hard mask to define a gate stack and spacer between gate stack and select gate electrode. A gate dielectric layer can be used for the select gate electrode and transistors in a low-voltage region and allows for a fast read access time.Type: GrantFiled: February 5, 2021Date of Patent: January 3, 2023Assignee: SEMICONDUCTOR COMPONENTS INDUSTRIES, LLCInventors: Weize Chen, Sameer S.
