Patent ID: 7619251

Claim:
A semiconductor device comprising: a glass substrate having a strain point not higher than 750° C.; a semiconductor film having Si as a chief component and being formed on at least a part of the glass substrate; a pixel region formed with pixels for displaying an image, said pixel region including a part of the semiconductor film; and a circuit for driving the pixels of the pixel region; wherein at least one region of the semiconductor film having crystals grown laterally as irradiated with a CW laser beam is included in at least as a part of the circuit, and a difference between a tensile stress of a surface of glass of the glass substrate in said region that is grown with the crystals laterally and a tensile stress of a surface of glass of the glass substrate in the pixel region is not larger than 200 N/m, and wherein a tensile stress of a surface of glass of the glass substrate in a direction perpendicular to a growth direction of the laterally grown crystals of the semiconductor film is higher than a tensile stress of a surface of glass of the glass substrate in the growth direction, in said region that is grown with the crystals laterally.
