Method of forming ONO-type sidewall with reduced bird's beak

Conventional fabrication of sidewall oxide around an ONO-type memory cell stack usually produces Bird's Beak because prior to the fabrication, there is an exposed sidewall of the ONO-type memory cell stack that exposes side parts of a plurality of material layers respectively composed of different materials. Certain materials in the stack such as silicon nitrides are more difficult to oxidize than other materials in the stack such polysilicon. As a result oxidation does not proceed uniformly along the multi-layered height of the sidewall. The present disclosure shows how radical-based fabrication of sidewall dielectric can help to reduce the Bird's Beak formation. More specifically, it is indicated that short-lived oxidizing agents (e.g., atomic oxygen) are able to better oxidize difficult to oxidize materials such as silicon nitride and the it is indicated that the short-lived oxidizing agents alternatively or additionally do not diffuse as deeply through already oxidized layers of the sidewall such as silicon oxide layers. As a result, a more uniform sidewall dielectric can be fabricated with more uniform breakdown voltages along it height.

Total ionizing dose suppression transistor architecture

A total ionizing dose suppression architecture for a transistor and a transistor circuit uses an “end cap” metal structure that is connected to the lowest potential voltage to overcome the tendency of negative charge buildup during exposure to ionizing radiation. The suppression architecture uses the field established by coupling the metal structure to the lowest potential voltage to steer the charge away from the critical field (inter-device) and keeps non-local charge from migrating to the “birds-beak” region of the transistor, preventing further charge buildup. The “end cap” structure seals off the “birds-beak” region and isolates the critical area. The critical area charge is source starved of an outside charge. Outside charge migrating close to the induced field is repelled away from the critical region. The architecture is further extended to suppress leakage current between adjacent wells biased to differential potentials.

Bird's beak-less or STI- less OTP EPROM

The present invention facilitates semiconductor fabrication by maintaining uniform thickness of a gate oxide layer (112) during the oxide growth process of non-volatile memory devices (100). The uniform thickness of a gate oxide layer (112) is obtained by defining the boundaries of the source and drain areas (110) of a memory device (100) with the source / drain dopant masking and implanting operation. If an isolation barrier (108) is present it is kept a minimum safe distance (130) away from the periphery of the conductive gate layer (114) to avoid birds-beak regions (30) responsible for non-uniform gate oxide growth. As a result, the corresponding charge losses and weak cells are mitigated, thereby facilitating the fabrication of more reliable memory cells (100). Because a more uniform gate oxide thickness (112) is used in association with the memory cells (100), a single significantly thinner gate oxide layer (114) may be employed throughout the memory device (100). In this way, the same gate oxide layer (114) may be used by an NVM device (100) embedded with common CMOS devices to reduce wafer manufacturing costs.
