Abstract:
A method for manufacturing a semiconductor thin film is provided which can form its crystal grains having a uniform direction of crystal growth and being large in size and a manufacturing equipment using the above method, and a method for manufacturing a thin film transistor. In the above method, by applying an energy beam partially intercepted by a light-shielding element, melt and re-crystallization occur with a light-shielded region as a starting point. The irradiation of the beam gives energy to the light-shielded region of the silicon thin film so that melt and re-crystallization occur with the light-shielded region as the starting point and so that a local temperature gradient in the light-shielded region is made to be 1200° C./μm or more. In the manufacturing method, a resolution of an optical system used to apply the energy beam is preferably 4 μm or less.

Abstract:
A semiconductor film formation method allowing a single-crystal semiconductor film to be formed at a desired position on a substrate with reliability is disclosed. After preparing the substrate having a non-single-crystal semiconductor film formed thereon and an optical mask having a predetermined pattern, a projection area of the optical mask is relatively positioned at the desired position on the substrate. Thereafter, the desired position of the non-single-crystal semiconductor film is irradiated with laser light through the optical mask to change an irradiated portion of the non-single-crystal semiconductor film to the single-crystal semiconductor film. Then, an insulation film is formed on at least the single-crystal semiconductor film.

For a semiconductor device S as an inspected object, there are provided an image acquisition part 1, an optical system 2 including an objective lens 20, and a solid immersion lens (SIL) 3 movable between an insertion position including an optical axis from the semiconductor device S to the objective lens 20 and a standby position off the optical axis. Then observation is carried out in two control modes consisting of a first mode in which the SIL 3 is located at the standby position and in which focusing and aberration correction are carried out based on a refractive index no and a thickness to of a substrate of the semiconductor device S, and a second mode in which the SIL 3 is located at the insertion position and in which focusing and aberration correction are carried out based on the refractive index no and thickness t0 of the substrate, and a refractive index n1, a thickness d1, and a radius of curvature R1 of SIL 3. This provides a microscope and a sample observation method capable of readily performing observation of the sample necessary for an analysis of microstructure or the like of the semiconductor device.
