    Abstract: The present invention provides an improved amorphization/templated recrystallization (ATR) method for fabricating low-defect-density hybrid orientation substrates. ATR methods for hybrid orientation substrate fabrication generally start with a Si layer having a first orientation bonded to a second Si layer or substrate having a second orientation. Selected regions of the first Si layer are amorphized and then recrystallized into the orientation of the second Si layer by using the second Si layer as a template. In particular, this invention provides a melt-recrystallization ATR method, for use alone or in combination with non-melt-recrystallization ATR methods, in which selected Si regions bounded by dielectric-filled trenches are induced to undergo an orientation change by the steps of preamorphization, laser-induced melting, and corner-defect-free templated recrystallization from the melt.

    Abstract: The present invention provides a method of fabricating a SiGe-on-insulator substrate in which lattice engineering is employed to decouple the interdependence between SiGe thickness, Ge fraction and strain relaxation. The method includes providing a SiGe-on-insulator substrate material comprising a SiGe alloy layer having a selected in-plane lattice parameter, a selected thickness parameter and a selected Ge content parameter, wherein the selected in-plane lattice parameter has a constant value and one or both of the other parameters, i.e., thickness or Ge content, have adjustable values; and adjusting one or both of the other parameters to final selected values, while maintaining the selected in-plane lattice parameter. The adjusting is achieved utilizing either a thinning process or a thermal dilution process depending on which parameters are fixed and which are adjustable.

    Abstract: PROBLEM TO BE SOLVED: To provide a method for amorphization/template re-crystallization for changing orientation in the selected region of a silicon, without remaining defect of high density, by preparing an anneal process optimized to remove defects caused by damage due to injection, in a single crystal silicon. SOLUTION: The region of Si having a first crystal orientation is amorphised by iron-implantation, and is re-crystallized into the orientation of a template layer having different orientation, in an amorphising/template re-crystallization (ATR) process. A reoriented Si of low defective density in the process is formed by this method. More specifically, the invention relates to a high temperature annealing condition required for eliminating defects remaining in an Si-contained single crystal semiconductor material formed of the layer whose orientation is identical or different from the original orientation of amorphous layer by amorphising caused by ion-implantation and template re-crystallization. The main factor of that is a thermal process for removing defects remaining after initial re-crystallization annealing, in the temperature range of 1,250-1,330°C for several minutes to several hours. A reoriented Si of low defective density, formed by ATR, is provided as well for use with a hybrid orientation substrate. COPYRIGHT: (C)2006,JPO&NCIPI

    Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing an SiGe-on-insulator substrate material substantially relaxed, of high quality, and capable of being used as a template for strained-silicon. SOLUTION: The SOI substrate having an ultra-thin top Si layer is used as the template for compressive strain SiGe growth. When an SiGe layer is relaxed at an enough temperature, the property of its dislocation movement is such that strain release defect moves down into the thin Si layer when an embedded oxide shows semi-viscosity behavior. The thin Si layer is consumed by oxidation of an interface of the thin Si with the embedded oxide. This can be performed by using inner oxidation at a high temperature. Therefore, the role of the original thin Si layer is to use the inner oxidation and subsequently to act as a sacrificial defective sink capable of being consumed during an SiGe alloy being relaxed.
