Abstract:Nowadays IC components get smaller and smaller, but the die sizes increase. To be able to interconnect the large dies from one side to another and in‐between IC’s a new LED has been developed for on‐chip optical communication. In this work the switching behavior of a 5nm ultrathin silicon PIN LEDs has been investigated. To do so first simulations of regular PIN diodes have been performed. These have been extended to simulations of the 5nm ultrathin diodes in different geometries. The DC‐simulations have been compared to existing measurements results. When both the simulation and the measurements matched, transient simulations have been run to take a look at the switching behavior and speed. The simulation results show that there is a huge potential for the new 5nm ultrathin devices. Some premature measurements did unfortunately not show this potential yet because of oscillation occurring in the measurement setup, but might in the future confirm the simulations. A setup for transient electrical measurements as well a for optical measurements has been proposed and can be of use in future research on the newly developed ultrathin PIN LEDs.
