Optimized substrate geometries reduce the detrimental effect of total internal reflection and thus improve LED performance. A semiconductor fabrication technique that enables particularly advantageous substrate patterning is anisotropic wet etching of sapphire. The resulting three-dimensional etch profiles are complex and need to be accurately predicted to find the ideal process parameters for maximal LED efficiency.<\/p>\n<p>In this webinar, a workflow that combines process and device TCAD to support the design of GaN-based LEDs is presented. The workflow integrates three-dimensional process simulation capabilities (Silvaco Victory Process), physical models for wet etching of sapphire, and light extraction ray-tracing calculations (Silvaco Victory Device). Thus, the impact of process parameters on LED performance is quantified.<\/p>\n<p>What attendees will learn:<\/p>\n<ul>\n<li>Capabilities of Silvaco Victory Process for strongly anisotropic etching<\/li>\n<li>How to model the intricate wet etching anisotropy of sapphire<\/li>\n<li>How Process and Device TCAD can be combined<\/li>\n<li>Impact of patterned sapphire substrates on GaN-based LEDs<\/li>\n<\/ul>\n<h2>Presenter<\/h2>\n<p><img decoding=\"async\" class=\"wp-image-17179 alignleft\" src=\"https:\/\/silvaco.com\/wp-content\/uploads\/2021\/05\/toifl_alexander-243x300.png\" alt=\"Alexander Toifl\" width=\"86\" height=\"106\" srcset=\"https:\/\/silvaco.com\/wp-content\/uploads\/2021\/05\/toifl_alexander-243x300.png 243w, https:\/\/silvaco.com\/wp-content\/uploads\/2021\/05\/toifl_alexander-30x37.png 30w, https:\/\/silvaco.com\/wp-content\/uploads\/2021\/05\/toifl_alexander-44x55.png 44w, https:\/\/silvaco.com\/wp-content\/uploads\/2021\/05\/toifl_alexander-39x48.png 39w, https:\/\/silvaco.com\/wp-content\/uploads\/2021\/05\/toifl_alexander.png 550w\" sizes=\"(max-width: 86px) 100vw, 86px\" \/>Alexander Toifl is currently in the final stage of pursuing a doctoral degree in the area of process TCAD with the Christian Doppler Laboratory for High Performance at the Institute for Microelectronics, TU Wien, Austria.
