Die-Attach

Die-attach involves securing semiconductor dies—typically Si, SiC, GaAs, or GaN—to a leadframe or substrate. This step is essential in establishing a mechanically reliable interconnection while also ensuring that the thermal and electrical properties meet the application’s requirements. The levels of reliability, thermal conductivity, and electrical conductivity vary across applications, highlighting the importance of selecting the most suitable die-attach material. As a trusted partner in optimizing existing processes and developing innovative solutions, Indium Corporation offers a wide range of die-attach solutions from solder paste, specialty preforms to sinter materials.
