Latest Patents

One of Shengnian's latest patents revolves around semiconductor memory devices and methods for fabricating them, specifically regarding a dual-bit EEPROM semiconductor device. This invention includes a semiconductor substrate with a tunnel oxide, and features first and second spaced apart floating gates sitting on the tunnel oxide. An interlayer dielectric layer provides electrical isolation between these floating gates and also contacts the tunnel oxide layer at a critical position. A control gate is strategically placed to contact the interlayer dielectric between the two spaced floating gates.

Another noteworthy patent concerns the method of fabricating conductor structures while avoiding metal comb bridging. This patent presents various methods for inspecting a workpiece for residue, and outlines a process which involves forming an aluminum-copper film on a substrate in one processing chamber and applying an anti-reflective coating in another. The substrate undergoes a cooling quench, and specific time intervals are measured during the fabrication process. This method significantly mitigates the risk of device failures due to metal comb bridging after the etch definition of conductor lines.
