A multi-physics multi-scale modeling platform has been developed and it has been applied to various stages of the LED manufacturing such as MOCVD reactor design, epitaxial growth based on silicon wafer, chip design and manufacturing, module packaging and assembly, and specific lamps. Discussions are also given to the ultra-scalable reactor design, material constitutive modeling, and curvature evolution prediction during a complete MOCVD processing, effect of defects and interface integrity, behaviors of thermal, optical, deformation, and stresses. First principles Molecular dynamics (MD) and finite element method (FEM) have been used in couple to study the scale effect of the material properties and the prediction of the module behaviors. A few examples of applications have been given, including the applications to a few real world lamps such as tunnel lamps, street lamps, and MR16.
