    摘要: A method of forming substrates, e.g., silicon on insulator, silicon on silicon. The method includes providing a donor substrate, e.g., silicon wafer. The method also includes forming a cleave layer on the donor substrate that contains the cleave plane, the plane of eventual separation. In a specific embodiment, the cleave layer comprising silicon germanium. The method also includes forming a device layer (e.g., epitaxial silicon) on the cleave layer. The method also includes introducing particles into the cleave layer to add stress in the cleave layer. The particles within the cleave layer are then redistributed to form a high concentration region of the particles in the vicinity of the cleave plane, where the redistribution of the particles is carried out in a manner substantially free from microbubble or microcavity formation of the particles in the cleave plane. That is, the particles are generally at a low dose, which is defined herein as a lack of microbubble or microcavity formation in the cleave plane. The method also includes providing selected energy to the donor substrate to cleave the device layer from the cleave layer at the cleave plane, whereupon the selected energy is applied to create a controlled cleaving action to remove the device layer from a portion of the cleave layer in a controlled manner.

    摘要: Methods and systems for permitting thickness control of the selective epitaxial growth (SEG) layer in a semiconductor manufacturing process, for example raised source/drain applications in CMOS technologies, are presented. These methods and systems provide the capability to measure the thickness of an SEG film in-situ utilizing optical ellipsometry equipment during or after SEG layer growth, prior to removing the wafer from the SEG growth tool. Optical ellipsometry equipment can be integrated into the SEG platform and control software, thus providing automated process control (APC) capability for SEG thickness. The integration of the ellipsometry equipment may be varied, dependent upon the needs of the fabrication facility, e.g., integration to provide ellipsometer monitoring of a single process tool, or multiple tool monitoring, among other configurations.

The device under measurement is connected from its drain to a measuring circuit having a trip point switching circuit.
