Latest Patents

One of Efraim Aloni's latest patents is a method for fabricating capacitor structures using the first contact metal. This method allows for the fabrication of capacitor structures with only slight modifications to a conventional single-poly CMOS process. After completing front-end processing, grooves are etched through the pre-metal dielectric layer to expose polysilicon structures, which may be salicided or non-salicided. A dielectric layer is then formed over the exposed polysilicon structures, followed by a conventional contact process module to form contact openings. The mask used for these openings is removed, and conventional contact metal deposition steps are performed, filling both the contact openings and grooves with the contact metal stack. A planarization step removes the upper portion of the metal stack, leaving metal contacts in the openings and metal electrodes in the grooves, which can serve as transistor gates, EEPROM control gates, or capacitor plates.

Another notable patent is the development of a single poly CMOS logic memory cell for RFID applications and its programming and erasing method. This electrically erasable/programmable CMOS logic memory cell includes a tunneling capacitor, a control capacitor, and a CMOS inverter that share a single floating gate. The programming and erasing process involves a two-phase operation that utilizes low currents and low voltages, ensuring efficiency and effectiveness in mobile applications.
