Abstract :
We fabricated 0.22 μm triple well CMOS with deep p-well, doped with 1×1014 B ions/cm2, implanting with energy of 1.7 MeV by using high energy ion implantation equipment and thermal processes at 950°C, 30 min by FA and at 1100°C, 30 sec by RTA. The electrical characteristics which were compared and analyzed for each thermal treatment are junction leakage current and junction breakdown voltage and sub-threshold current- and latch-up immunity. We propose that RTA is superior to FA in thermal process from the viewpoint of electrical characteristics. We obtained excellent leakage currents and junction breakdown voltage characteristics by RTA process
