Abstract:
A method of manufacturing an active matrix device having an active matrix circuit comprising a matrix of thin film transistors and a source driver circuit for supplying signals to said active matrix circuit, said driver circuit including at least a plurality of analog buffers arranged in a first direction with a pitch d, said method comprising the steps of:forming a semiconductor film over a substrate;irradiating said semiconductor film with a light beam wherein a cross section at a surface of said semiconductor film is elongated in a second direction orthogonal to said first direction;scanning said semiconductor film with the light beam in the first direction to crystallize said semiconductor film; andforming at least said active matrix circuit and said analog buffers by using the semiconductor film crystallized by said light beam,wherein a width in the first direction of said cross section of the light beam is equal to an n multiple of the pitch d where n is an integer.
