Selective growth method, and semiconductor light emitting device and fabrication method thereof
InactiveUS6858081B2Improve featuresReduce widthPolycrystalline material growthSemiconductor/solid-state device manufacturingThree dimensional shapeActive layer
In a selective growth method, growth interruption is performed at the time of selective growth of a crystal layer on a substrate. Even if the thickness distribution of the crystal layer becomes non-uniform at the time of growth of the crystal layer, the non-uniformity of the thickness distribution of the crystal layer can be corrected by inserting the growth interruption. As a result of growth interruption, an etching rate at a thick portion becomes higher than that at a thin portion, to eliminate the difference in thickness between the thick portion and the thin portion, thereby solving the problem associated with degradation of characteristics due to a variation in thickness of the crystal layer, for example, an active layer. The selective growth method is applied to fabrication of a semiconductor light emitting device including an active layer as a crystal layer formed on a crystal layer having a three-dimensional shape by selective growth.

Semiconductor device stress modeling methodology
InactiveUS20080195983A1Improve accuracyEliminate differencesComputation using non-denominational number representationDesign optimisation/simulationData setComputational model
A computational methodology that improves the accuracy of model parameters in a compact model uses methods and algorithms to self-consistently match independently developed base and stress models by re-fitting the stress model to the data set that generates the base model. The re-fitting algorithm removes any discrepancy between the base model and the stress model as the stress model is applied to the data set obtained from a dimension-scaling macro. Stress offsets for dimension-scaling macro devices are calculated to fit the measured values of the model parameters for the same devices. The process of fitting the model parameters to the data set from the dimension-scaling macro calculates constant, linear, and quadratic coefficients for the model parameters, which are employed to increase the accuracy of the model parameters and of the compact model used in circuit simulations and optimization.
