Latest Patents
One of his latest patents is focused on spacer-less low-K dielectric processes. This invention provides a method for removing first spacers from gates and incorporating a low-k material into the interlayer dielectric (ILD) layer, which significantly increases device performance. Another embodiment of this patent involves replacing the first spacers after silicidation with low-k spacers, effectively reducing parasitic capacitances. By implementing low-k spacers only after silicidation, the integrity of these spacers is maintained through multiple high-dose ion implantations and resist strip steps. These advancements can notably improve the performance of devices, such as rim oscillators. Additionally, he has developed a method to remove spacers after salicidation to enhance contact etch stop liner stress on MOS transistors. This process involves forming a stress-creating layer over NMOS and PMOS transistors, allowing for improved performance of NMOS transistors by positioning the stress layer closer to the channel of the device.
