Abstract :
The paper presents the thermal design process of a transmitter chip by means of analytical solutions and numerical simulation. Thermo-electrical models representing the heat transfer mechanisms were developed. Parametric simulation studies have been applied for the device optimization. Special emphasis was put onto the multi-scale problem that appears with very small heat sources and dimensions in the square-micrometer range respectively. Submodeling technique is used to manage associated numerical difficulties. A parametric model is generated for a transmitter module with multiple transistor blocks on single chip. The model is validated by analytical solutions for heat sources on finite regions and associated experimental temperature measurements on wafer. Solutions and results of the parametric design studies are presented
