Title: Avi Ben-Gigi: Innovator in SONOS Memory Technology
Introduction
Avi Ben-Gigi is a notable inventor based in Migdal Haemek, Israel. He has made significant contributions to the field of semiconductor technology, particularly in the development of SONOS memory structures. With a total of 3 patents to his name, his work has had a substantial impact on the industry.
Latest Patents
One of Avi Ben-Gigi's latest patents focuses on protection against in-process charging in silicon-oxide-nitride-oxide-silicon (SONOS) memories. This innovation involves a pre-metal dielectric structure that includes a UV light-absorbing film. This film prevents the ONO structure from being electronically charged in response to UV irradiation. The design features a first pre-metal dielectric layer over the SONOS memory structure, a light-absorbing structure above it, and a second pre-metal dielectric layer on top. The light-absorbing structure can be made of continuous polysilicon or amorphous silicon, or it can consist of patterned polysilicon layers. Another embodiment includes SONOS transistors that feature UV light-absorbing polysilicon spacers.
Another significant patent by Ben-Gigi is a method for decreasing charging effects in oxide-nitride-oxide (ONO) memory arrays. This invention describes a fieldless array that includes a semiconductor substrate and multiple ONO structures formed over its surface. Word lines are placed over the ONO structures, effectively blocking UV irradiation during processing steps. This design prevents electrons from being trapped in the silicon nitride layer of the ONO structure, ensuring that the threshold voltages of the fieldless array transistors do not severely increase as their width decreases.
