Latest Patents
One of Jer-Yuan Sheu's latest patents focuses on a polysilicon load for 4T SRAM operating at cold temperatures. This invention addresses the fabrication of integrated circuit devices, specifically targeting the excessive negative temperature coefficient of resistance (TCR) in low doped polysilicon load resistors used in sub-micron, NMOS-based, 4 transistor SRAM cells. The invention introduces a novel PN junction approach that allows polysilicon resistors to become electrically thicker at colder temperatures. By forming a vertical PN junction along the entire length of a polysilicon resistor, the temperature-dependent space charge region of the PN junction modulates the effective electrical thickness of the resistor. This innovation helps mitigate cell failures that can occur when operating currents approach device leakage currents at low temperatures, enabling 4T SRAMs to function effectively at temperatures as low as -45°C without significantly complicating the fabrication process.
