46results about How to "Difference in thickness" patented technology

Selective growth method, and semiconductor light emitting device and fabrication method thereof

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.

Dynamic wafer leveling/tilting/swiveling during a chemical vapor deposition process

The implementations described herein generally relate to the dynamic, real-time control of the process spacing between a substrate support and a gas distribution medium during a deposition process. Multiple dimensional degrees of freedom are utilized to change the angle and spacing of the substrate plane with respect to the gas distributing medium at any time during the deposition process. As such, the substrate and / or substrate support may be leveled, tilted, swiveled, wobbled, and / or moved during the deposition process to achieve improved film uniformity. Furthermore, the independent tuning of each layer may be had due to continuous variations in the leveling of the substrate plane with respect to the showerhead to average effective deposition on the substrate, thus improving overall stack deposition performance.
