With a total of 2 patents to his name, Roubakha's work has advanced the capabilities of circuit design and manufacturing.
Latest Patents
Roubakha's latest patents include an innovative antifuse based on silicided polysilicon bipolar transistors. This improved antifuse utilizes the base-emitter junction of a silicided single polysilicon bipolar transistor. The design features a shortened distance between the base metal and emitter metal, achieved through self-aligning process steps rather than traditional lithographic methods. This results in a lower and better-controlled programming voltage, programming energy, and ON state resistance. The conductive filament formed in this new antifuse is approximately 0.65 microns long and is created by a voltage pulse with a relatively slow rise time of about 150 microseconds. These enhancements provide significant advantages in circuit design and manufacturing processes.
Another patent by Roubakha details a method of making an antifuse based on silicided single polysilicon bipolar transistors. Similar to his previous work, this invention focuses on optimizing the distance between the base and emitter metals, leading to improved performance characteristics.
