Abstract: A method for producing a thin film semiconductor device is described. In the method, a thin film layer of non-single-crystalline semiconductor, which is deposited on a base layer of glass, is processed to an island-shaped thin film layer at the time prior to the layer irradiation step. The laser irradiation to the thin film layer of non-single-crystalline semiconductor is carried out after forming an insulation film layer and a gate electrode over the island-shaped thin film layer, by using the gate electrode as the irradiation mask, whereby the center area of the island-shaped thin film layer masked by the gate electrode is crystallized, and simultaneously, the both side areas thereof which is not masked by the gate electrode are annealed. Next, a source electrode and a drain electrode is formed in the annealed areas. The implantation of impurity ion may be carried out either before or after the laser irradiation.

Abstract: A thin film semiconductor device and a method for producing it are described. In the thin film layer of semiconductor of the device, a plurality of large size single-crystalline grains of semiconductor are formed in a regulated configuration, and each of single crystalline grains is equipped with one unit of electric circuit having a gate electrode, a source electrode and drain electrode. Such regulated arrangement of large size single-crystalline grains in the semiconductor layer is realized by a process including a step of irradiating the layer of amorphous or polycrystalline semiconductor with energy beam such as excimer laser so that maximum irradiation intensity points and minimum irradiation intensity points are arranged regulatedly. The device can have a high mobility such as about 500 cm2/V sec.

Abstract: A liquid crystal module comprises a liquid crystal panel including mutually orthogonal row electrodes and column electrodes and a liquid crystal layer sealed between the electrodes as a display element, a row electrode driving circuit driving the row electrodes of the liquid crystal panel, and a column electrode driving circuit driving the column electrodes. A detecting electrode detects scanning signals applied to the row and column electrodes of the liquid crystal panel by electrically coupling to the electrodes with electrostatic coupling capacity. A coordinate detecting circuit converts the signals obtained from the detecting electrode into row and column coordinates. A correction arithmetic circuit corrects positional differences by using correction parameters of the device which have been obtained from output values of the coordinate detecting circuit beforehand. The display-integrated coordinate input device improves detection precision at the edges of a matrix panel.

Abstract: A substrate is exposed to a gas of reactive material and an oxidizing gas. The oxidizing gas includes an ozone gas. A laser light beam is applied to the substrate through the reactive material gas and the oxidizing gas. The laser light beam activates the oxidizing gas. The activated oxidizing gas reacts with the reactive material gas to form an oxide deposited on the substrate.
