Latest Patents

One of Jeong Gil Lee's latest patents involves semiconductor devices and methods of forming the same. This patent describes semiconductor devices that include multiple gate electrodes stacked on a substrate, spaced apart in a vertical direction, with a channel region extending through these electrodes. Each gate electrode features a first conductive layer that defines a recess toward the channel region, along with a second conductive layer within this recess. Notably, the first concentration of impurities in the second conductive layer is higher than that in the first conductive layer, with nitrogen (N) being one of the key impurities.

Another significant patent outlines a method for manufacturing semiconductor devices. This method includes alternately stacking sacrificial layers and interlayer insulating layers on a substrate to create a stack structure. It also involves forming channels and separation regions that penetrate through the stack structure, as well as creating lateral openings by removing the sacrificial layers. The formation of gate electrodes in these openings includes creating a nucleation layer and a bulk layer through the supply of specific source gases.
