Latest Patents
Khan's latest patents include innovative methods for improving the lifetime of short-channel NMOS devices. His first patent describes FETs having lightly doped drain regions that are shaped with counter and noncounter dopant elements. This invention increases the lifetime of a short-channel NMOS device by modifying the distributions of electrically active LDD dopants at the boundaries of the device's LDD regions. By implanting counter-dopants at these boundaries, such as group III elements like boron and group IV elements like silicon, the activation properties of the LDD dopants are altered. This modification reduces the maximum electric field displacement at the interface defined by the device's gate and substrate, allowing for better performance.
Another significant patent by Khan involves the method of forming retrograde well structures and punch-through barriers. In this patent, a retrograde well in a CMOS device is formed using a low-energy ion implanter. Dopant atoms are implanted into the bare surface of the device's substrate in a direction orthogonal to the substrate surface. The well implant can be performed at an energy below 220 keV, and chained implants for a punch-through barrier can be executed after the well implant. This process ensures that the punch-through barrier is activated simultaneously with the retrograde well during substrate annealing.
