摘要： An SOI substrate having no worry about a fluctuation in electrical characteristics due to generation of oxygen donors is provided.A silicon substrate 10 used for bonding is a single-crystal Si substrate in which an interstitial oxygen concentration measured by infrared absorption spectrophotometry is equal to or below 1×1018 cm−3. The interstitial oxygen concentration of the single-crystal silicon substrate is set to 1×1018 cm−3 or below since a degree of formation of oxygen donors is strongly dependent on the interstitial oxygen concentration. When the interstitial oxygen concentration of the crystal silicon substrate is set to 1×1018 cm−3 or below, a fluctuation in electrical characteristics (a resistivity) of a silicon layer (an SOI layer) of an SOI substrate can be suppressed to a practically problem-free level. Such a single-crystal silicon substrate can be readily obtained by an MCZ method that can control a convection of a silicon melt by applying a magnetic field or an FZ method that uses no quartz crucible.

摘要： The present invention enables reducing a temperature in a manufacturing process of an SOI substrate.A hydrogen ion is implanted into a surface of a single-crystal Si substrate 10 via an oxide film 11 to form a uniform ion implantation layer 12 at a predetermined depth near a surface of the single-crystal Si Substrate 10. At this time, ion implantation is carried out under a condition that a temperature of the Si substrate 10 is maintained so as not to exceed 400° C. Subsequently, a heat treatment is performed with respect to the single-crystal Si substrate 10 at a temperature of 400° C. or below. This heat treatment is effected to weaken mechanical strength of an “implantation interface” of the ion implantation layer 12 in advance prior to a delamination step, and the heat treatment temperature is set to 400° C. or below in order to suppress occurrence of “micro cavities” and “air bubble growth”. A plasma treatment or an ozone treatment is carried out to joint surfaces of both substrates, and an external impact shock is given in a state where the substrates are bonded to each other to mechanically delaminate a silicon film 13 from a bulk 14 of the single-crystal silicon, thereby obtaining an SOI film 13 provided on a quartz substrate 20 via the oxide film 11.

摘要： Hydrogen ions are implanted to a surface (main surface) of the single crystal Si substrate 10 at a dosage of 1.5×1017 atoms/cm2 or higher to form the hydrogen ion implanted layer (ion-implanted damage layer) 11. As a result of the hydrogen ion implantation, the hydrogen ion implanted boundary 12 is formed. The single crystal Si substrate 10 and the low melting glass substrate 20 are bonded together. The bonded substrate is heated at relatively low temperature, 120° C. or higher and 250° C. or lower (below a melting point of the support substrate). Further, an external shock is applied to delaminate the Si crystal film along the hydrogen ion implanted boundary 12 of the single crystal Si substrate 10 out of the heat-treated bonded substrate. Then, the surface of the resultant silicon thin film 13 is polished to remove a damaged portion, so that a semiconductor substrate can be fabricated. There can be provided a semiconductor substrate in which a high-quality silicon thin film is transferred onto a substrate made of a low melting point material.
