In this paper, 5-mask-count array process using light shield layer acted as source and drain layer, which is the first layer on the glass substrate, is studied. The device mobility and the threshold voltage is 13.3 cm2/Vs and 0.20V, respectively, which is reached to the considerable level of conventional top-gate self-aligned device.
