A second insulation layer which is formed by stacking a plurality of layers made of different materials in a mutually contact manner is formed such that the second insulation layer covers a source region and a drain region and also covers a gate electrode from above. A first contact hole which reaches one of the source region and the drain region and a recessed portion which is arranged above the gate electrode but is not communicated with the gate electrode are simultaneously formed on the second insulation layer by dry etching. A first line layer is formed so as to cover the first contact hole. After forming the first line layer, a bottom surface of the recessed portion is etched by dry etching thus forming a second contact hole which reaches the gate electrode in the first and second insulation layers. A second line layer is formed on the second contact hole.

A needle 2 includes a plunger member 21 and a collar member 22, and is provided to be reciprocable from a latch position to a latch release position inside a stator 1. A first magnet coil 31 has sufficient electromagnetic power to put in a latch state the needle 2 which is in a latch release state on energization. A permanent magnet 4 has sufficient absorption power for absorbing a collar member 22 of the needle 2 put in the latch state by the electromagnetic power of the first magnet coil 31 and maintaining the latch state even when the first magnet coil 31 is in a non-energized state. A second magnet coil 32 can diminish magnetic fluxes of the permanent magnet 4 and change the needle 2 from the latch state to the latch release state on energization. Thus, energy efficiency is improved by varying how to energize the magnet coils according to the state of a load side.

The present invention provides a display-device-use substrate which is strip-crystallized while minimizing the generation of peeling of a semiconductor by suppressing the generation of aggregation at the time of crystallization due to the radiation of continuous oscillation laser beams. A silicon nitride film and a silicon oxide film which constitutes a background film are formed on a glass substrate on which projecting portions are formed, and a silicon base film is formed on the silicon nitride film and a silicon oxide film. Banks which intersect the scanning directions of laser beams are positioned below the silicon base substrate. The aggregation which is generated by the scanning of laser beams is stopped at a portion after the laser beams gets over the bank and, thereafter, the strip crystal silicon film is formed normally.

A mechanism for always measuring the spatial intensity distribution of a laser beam and displacement of the optical axis of the laser beam is provided so that a measured signal is processed when the laser beam incident on a laser beam shaping optical element is out of a predetermined condition. The shape, diameter and incidence position of the laser beam incident on the laser beam shaping optical element are always kept in the predetermined condition by a spatial filter disposed at the position of a focal point of lenses forming a beam expander disposed in the optical axis, on the basis of a result of the signal processing.In this manner, silicon thin films uniform in crystallinity can be formed stably with a high yield on an insulating substrate which forms display panels of flat panel display devices.

An interlayer insulating film containing hydrogen is formed on the sub-gate, main gate, and gate insulating film. Subsequently, a heat treatment for hydrogenation is performed to terminate a crystal defect of the semiconductor layer with hydrogen.
