摘要:
A radiation hardened static memory cell, methods of manufacture and design structures are provided. The method includes forming one or more first gate stacks and second gate stacks on a substrate. The method further includes providing a shallow implant process for the one or more first gate stacks such that diffusion regions of the one or more first gate stacks are non-butted junction regions. The method further includes providing a deep implant process for the one or more second gates stack such that diffusions regions of the one or more second gate stacks are butted junction regions.
摘要:
System and method for obtaining statistics in a fast and simplified manner at the wafer level while using wafer-level test equipment. The system and method performs a parallel stress of all of the DUTs on a given chip to keep the stress time short, and then allows each DUT on that chip to be tested individually while keeping the other DUTs on that chip under stress to avoid any relaxation. In one application, the obtained statistics enable analysis of Negative Temperature Bias Instability (NTBI) phenomena of transistor devices. Although obtaining statistics may be more crucial for NBTI because of its known behavior as the device narrows, the structure and methodology, with minor appropriate adjustments, could be used for stressing multiple DUTs for many technology reliability mechanisms.
