摘要： An embodiment includes depositing a material onto a substrate where the material includes a different lattice constant than the substrate (e.g., III-V or IV epitaxial (EPI) material on a Si substrate). An embodiment includes an EPI layer formed within a trench having walls that narrow as the trench extends upwards. An embodiment includes an EPI layer formed within a trench using multiple growth temperatures. A defect barrier, formed in the EPI layer when the temperature changes, contains defects within the trench and below the defect barrier. The EPI layer above the defect barrier and within the trench is relatively defect free. An embodiment includes an EPI layer annealed within a trench to induce defect annihilation. An embodiment includes an EPI superlattice formed within a trench and covered with a relatively defect free EPI layer (that is still included in the trench). Other embodiments are described herein.

摘要： Embodiments of the present invention describe a semiconductor device having an buffer structure and methods of fabricating the buffer structure. The buffer structure is formed between a substrate and a quantum well layer to prevent defects in the substrate and quantum well layer due to lattice mismatch. The buffer structure comprises a first buffer layer formed on the substrate, a plurality of blocking members formed on the first buffer layer, and second buffer formed on the plurality of blocking members. The plurality of blocking members prevent the second buffer layer from being deposited directly onto the entire first buffer layer so as to minimize lattice mismatch and prevent defects in the first and second buffer layers.

摘要： A microelectronic device includes a tunneling pocket within an asymmetrical semiconductive body including source- and drain wells. The tunneling pocket is formed by a self-aligned process by removing a dummy gate electrode from a gate spacer and by implanting the tunneling pocket into the semiconductive body or into an epitaxial film that is part of the semiconductive body.
