Latest Patents

Elif Berkman holds a patent for a "Method of manufacturing an adaptive AIGaN buffer layer." This method involves compensating for the resistivity of a near-surface region of a substrate by epitaxially growing a buffer layer. The buffer layer is designed with a dopant concentration that depends on the substrate's resistivity and conductivity. This technique effectively depletes residual or excess charge within the substrate's near-surface region. The dopant profile can be smoothly graded or consist of sub-layers with varying dopant concentrations, providing a highly resistive upper portion ideal for subsequent device growth. Additionally, the buffer layer may be doped with carbon, and aluminum can be utilized to getter the carbon during the epitaxial growth process.
