    摘要: The invention provides a method of producing a substrate comprising a thin crystalline layer transferred from a donor wafer onto a support, said thin layer including one or more foreign species intended to modify its properties, the method being characterized in that it comprises the following steps in sequence:

    implanting atomic species into a zone of the donor wafer (20) that is substantially free of foreign species (24), to form an embrittlement zone (22) below a bonding face, the embrittlement zone and the bonding face delimiting a thin layer (23) to be transferred;
    bonding the donor wafer (20), at the level of its bonding face, to a support (10);
    applying stresses in order to produce a cleavage in the region of the embrittlement zone (22) to obtain a substrate comprising the support (10) and the thin layer (23);
    and in that it further comprises a step of diffusing foreign species (24) into the thickness of the thin layer (23) prior to implantation or after fracture, suited to modify the properties of the thin layer, in particular its electrical or optical properties.
    Application to producing substrates with a thin InP layer rendered semi-insulating by iron diffusion.

    摘要: A multilayer semiconductor structure, formed of two or more separate layers of different materials can be selectively intermixed so as to become compositionally modified, such that the distinction between the different original materials is lost, at least partially. This intermixing process employs irradiation with a pulsed or rapidly scanned laser or electron beam, generally at ambient conditions of temperature and pressure, at energy levels which avoid physical damage to the layered structure. The intermixing may be more complete when multiple pulses from the laser or electron beam are employed.

    摘要: Closed tube methods have been employed to diffuse impurities selectively in a groups III - V semiconductor wafer. The closed tube methods are convenient for preventing the element of group V from dissociating out of the wafer surface by pressurizing the vapor pressure of the element of group V. Open tube methods failed in diffusing impurities without defects due to the fluctuation of the vapor pressure of the element of group V. Both methods have relied upon the vapor phase diffusion using a gas containing impurities. This invention adopts an open tube method of diffusing impurities in solid phase. This invention forms a suppression mask film having windows selectively on a wafer, and grows impurity-containing films on the windows by vapor phase reaction in an open reaction tube. The impurities diffuse from the impurity-containing films to the wafer substrate in solid phase. The impurity diffusion occurs either at the same time of the growth of the films or after the growth of the films at a different temperature. The compound semiconductor is covered with solid films during the impurity diffusion. This invention is immune from the difficulty of escape of elements of group V from the surface of a wafer.
