摘要： A predetermined species such as nitrogen is placed at an interface between a bit line junction and a dielectric layer of a control dielectric structure of a flash memory device to minimize degradation of such an interface by minimizing formation of interface defects during program or erase operations of the flash memory device. The predetermined species such as nitrogen is implanted into a bit line junction of the flash memory device. A thermal process is performed that heats up the semiconductor wafer such that the predetermined species such as nitrogen implanted within the semiconductor wafer thermally drifts to the interface between the bit line junction and the control dielectric structure during the thermal process. The predetermined species such as nitrogen at the interface minimizes formation of interface defects and thus degradation of the interface with time during the program or erase operations of the flash memory device.

摘要： A method for making a ULSI MOSFET includes covering core gate stacks with a first protective layer, etching away the first layer such that intended source regions of the substrate are exposed, and implanting dopant into the source regions. A second protective layer is then deposited over the first layer and is etched back to conform to the first layer, covering only the sides of the gate stacks, and exposing intended drain regions of the substrate. Dopant is then implanted into the drain regions. During subsequent manufacturing steps including ILD formation and metallization, mobile ions and other process-induced charges are blocked from entering the floating gates of the gate stacks by the protective layers, thereby preventing unwanted charge gain/loss.
