Latest Patents

One of Naem's latest patents is titled "Process of fabricating MOS devices having shallow source and drain." This invention describes a fabrication process where refractory metal is deposited over designated source and drain areas within a silicon substrate. The process involves mixing refractory metal and silicon at the interface through ion implantation of a heavy neutral ion species, such as germanium. To minimize source and drain junction depth, lighter ions like silicon are used to amorphize silicon to a predetermined depth, effectively confining dopant diffusion. This innovative approach allows for the creation of source and drain regions with desired conductivity types through subsequent ion implantation.

Another significant patent by Naem is "Structure and fabrication of vertically integrated CMOS logic gates." This invention presents a vertically integrated CMOS logic gate design featuring spaced semiconductor layers with control gates insulated by gate oxide. The transistors in one layer are vertically aligned with those in another, allowing for efficient use of space. The logic gate's function is determined by the voltages applied to the common control gates, enabling the creation of two-input NAND or NOR gates with reduced area requirements compared to traditional designs.
