Latest Patents

Among his latest patents, Bellezza has developed a "Process for fabricating a contactless electrical erasable EPROM memory." This innovative process utilizes relatively non-critical masks, allowing for the creation of high-density EEPROM or FLASH-EPROM devices. The method enables the fabrication of a contactless, cross-point array, which enhances the 'pitch' of bitline metal-definition while optimizing the cell layout with a gate structure that extends laterally over adjacent portions of field oxide. This design establishes an appropriate capacitive coupling between control and floating gates, with two alternative embodiments described.

Another significant patent is the "Method of making a matrix of EPROM memory cell with a tablecloth structure." This matrix comprises lines of source and drain that are parallel and alternated, with floating gate areas arranged in a checkerboard pattern. Control gate lines are superimposed over the substrate, aligned with the floating gate areas, and separated by field oxide areas, enhancing the overall functionality of the memory cells.
