Latest Patents

Armstrong's latest patents include innovative methods for forming high-density DRAM with increased capacitance area. One of his key inventions is a dynamic one-transistor read/write memory cell that employs a trench capacitor to amplify the magnitude of the stored charge. The trench is meticulously etched into the silicon surface at a diffused N+ capacitor region, which mirrors the structure of the N+ bit line. Subsequently, thick oxide is grown over the bit line and the capacitor region, while leaving the trench exposed. The upper plate of the capacitor consists of a polysilicon layer that extends into the trench, also providing field plate isolation over the silicon bar's face. Additionally, a refractory metal word line serves as the gate of the access transistor at a hole in the polysilicon field plate.
