A thin film semiconductor device has a semiconductor thin film with a film thickness of 200 nm or less. The semiconductor thin film is formed over a dielectric substrate with a warping point of 600° C. or lower. The semiconductor thin film has a region in which a first semiconductor thin film region with the defect density of 1×1017 cm−3 or less and a second semiconductor thin film region with the defect density of 1×1017 cm−3 or more are disposed alternately in the form of stripes. The width of the first semiconductor thin film region is larger than the width of the semiconductor thin film region. The grain boundaries, grain size and orientation of crystals over the dielectric substrate are controlled, so that a high quality thin film semiconductor device is obtained.

The present invention provides a method of manufacturing a thin-film transistor device. This method enables improvement in performance of a complementary TFT circuit incorporated in a thin- and light-weighted image display device or a flexible electronic device and also enables reduction of power consumption and reduction of manufacturing cost of the circuit. Further in the method, the number of manufacturing steps is decreased so that mass production and growth in size of thin film transistor devices are facilitated through a printing technique. In this method, electrodes forming n-type and p-type TFT and an organic semiconductor are made of the same material in both types of TFT by the solution-process and/or printable process method. A first polarizable thin-film 7 is formed on an interface between a gate insulator and a semiconductor, and also a second polarizable thin film 8 provided on an interface between source and drain electrodes 5 and a semiconductor film 9. A complementary thin-film transistor device is manufactured by selectively exposing either the n-type TFT area or the p-type TFT area to light to remove the polarizing function from the first and second polarizable thin films in the area.

There is provided a method for fabricating an image display device having an active matrix substrate including high-performance transistor circuits operating with high mobility as drive circuits for driving pixel portions which are arranged as a matrix. The portion of a polysilicon film formed in a drive circuit region DAR1 provided on the periphery of the pixel region PAR of the active matrix substrate SUB1 composing the image display device is irradiated and scanned with a pulse modulated laser beam or a pseudo CW laser beam to be reformed into a quasi-strip-like-crystal silicon film having a crystal boundary continuous in the scanning direction so that discrete reformed regions each composed of the quasi-strip-like-crystal silicon film are formed. In virtual tiles TL composed of the discrete reformed regions, drive circuits having active elements such as thin-film transistors or the like are formed such that the channel directions thereof coincide with the direction of crystal growth in the quasi-strip-like-crystal silicon film.

The process comprises having a means to shape laser light into a linear beam and a means to periodically and spatially modulate the intensity of pulsed laser in the direction of the long axis of the linear beam by passing through a phase-shifting stripy pattern perpendicular to the long axis, and collectively forming for each shot a polycrystalline film composed of crystals which have grown in a certain direction over the entire region irradiated with the linear beam.
