Laser irradiation method and method for manufacturing crystalline semiconductor film

Even when the laser irradiation is performed under the same condition with the energy distribution of the beam spot shaped as appropriate, the energy given to the irradiated surface is not yet homogeneous. When a semiconductor film is crystallized to form a crystalline semiconductor film using such inhomogeneous irradiation energy, the crystallinity becomes inhomogeneous in this film, and the characteristic of semiconductor elements manufactured using this film varies. In the present invention, an irradiated object formed over a substrate is irradiated with a laser beam having the pulse width that is an order of picosecond (10−12 second) or less.

Bonding method and apparatus

The invention provides a bonding device capable of shortening a bonding time and performing high speed and accurate mounting by irradiating a laser to an anisotropic conductive film (ACF) which is a mounting adhesive. Laser generated from a laser generator is reflected by a laser mirror, passes through an array substrate (glass substrate) through a backup glass, and then, directly irradiated to an ACF in a pinpoint manner. The laser from the laser generator is set to have a wavelength whose transmittance of transmitting the TCP and the array substrate having the ACF inserted therebetween is higher than that of the other wavelength. The ACF is welded by this laser irradiation, so that the TCP and the array substrate are bonded to each other.

Image heating apparatus

In an image heating apparatus in which a heating rotating body heats a recording material bearing an image and a rubbing member rubs the heating rotating body to eliminate gloss streaks, an image failure such as gloss unevenness does not occur in a normal plain paper and a coated paper, and a toner gloss on the coated paper can be enhanced. A longitudinal temperature difference of a heating rotating body 91 is controlled within a predetermined temperature, so that the surface of the heating rotating body can be uniformly roughed. Consequently, an image failure due to scuffs on the surface of the heating rotating body and gloss unevenness due to unevenness of roughness of the surface of the heating rotating body are prevented, and thus a good fixed image can be obtained.
