    Abstract: PROBLEM TO BE SOLVED: To provide a technology for forming self-assembled quantum dots having desirable optical characteristics. SOLUTION: The quantum dots are self-assembled InAs quantum dots 406 formed in InGaAs quantum wells 404 that are grown on a GaAs substrate by molecular beam epitaxy. A first AlGaAs or GaAs barrier layer 402 is grown. A first InGaAs well layer 404 is grown on the first barrier layer. A sufficient monolayer thickness of InAs is grown on the InGaAs, to form self-assembled islands. A second InGaAs well layer 404 is grown over the InAs islands to embed the quantum dots. A second AlGaAs or GaAs barrier layer 402 is then grown to complete the quantum well. Optical gain characteristics of the quantum well layers are influenced by the compositional uniformity of surrounding layers, the dot size distribution, the dot density, and the number of layers of the dots that can be placed in an active region without exceeding a critical thickness for forming dislocation.

    Abstract: PROBLEM TO BE SOLVED: To provide a method and apparatus for defining a single structure (11) on a semiconductor wafer by spatial frequency components. SOLUTION: Some of the spatial frequency components (12-16) are derived by optical lithography and some by interferometric lithography technology. Interferometric lithography images the high frequency components while optical lithography images the low frequency components. Optics collects many spatial frequencies and the interferometry shifts the spatial frequencies to high spatial frequencies. Thus, because a mask does not need to provide high spatial frequencies, the masks are configured to create only low frequency components. Thereby fabrication of simpler masks having larger structures is allowed. These methods and apparatus facilitate writing of more complex repetitive as well as non-repetitive patterns in a single exposure with a resolution which is higher than that currently available using known optical lithography alone.
