Abstract: | This project is entitled as semi-recessed LOCOS for CMOS device isolation. Local oxidation (LOCOS) technique is a widely used method for device isolation in semiconductor process integration. It is a simple, cheap yet and very effective to electrically isolating the highly packed devices down to 0.25um CMOS technology. Even though, the trench isolation is getting more popularity for 0.25um CMOS generation and below. The LOCOS isolation, due to its simplicity is still attractive for further scaling and improvement in semiconductor industry. The project is including several steps of process to produce the semi-recessed LOCOS. The main purpose of this project is to produces the small bird’s beak and varies on the pad oxide thickness whereby, the measurement is done using EDX (Energy dispersive X-ray spectroscopy) with the length setting 20 micron from boundary of an active area. From the results, it proved that the bird’s beak length is much depend on the pad oxide thickness whereby, the pad oxide should be at least 1/3 nitride thickness to work as a stress relief layer. |
