摘要： A thin film transistor (TFT) has lightly doped drains which includes heavily doped regions and lightly doped regions. The lightly doped drains are formed simultaneously by a single doping process through a gate insulating layer having different thicknesses. The TFT is fabricated by forming an active layer on an insulated substrate, forming an insulating layer on the active layer, forming a conductive layer on the insulating layer, forming a photoresist pattern on the conductive layer, forming a gate electrode by over etching the conductive layer by using the photoresist pattern as a mask. The first insulating layer is then partially etched by using the photoresist pattern as a mask. As a result, the portions of the first insulating layer overlapped by the photoresist pattern is thicker than the other portions not overlapped by the photoresist pattern. When the entire TFT is induced to impurities, the active regions substantial below the thicker insulating region form the lightly doped drains.

The TFT has a BBC (Buried Bus Coplanar) structure by forming a source/drain line on a substrate and by forming a buffer layer which covers the source/drain line which simplifies the process by means of reducing the number of deposition steps. The BBC structure of TFT has a source/drain line on a substrate, an insulating layer covering the source/drain line and the entire disclosed surface and a coplanar structure on the insulating layer. The present invention also provides a data line in the TFT of the BBC structure having low resistance applicable to a wide-screen by means of forming both the buffer layer and the source/drain line with a sufficient thickness.

摘要： A method is provided for fabricating a thin film transistor on a substrate. The method includes the steps of forming an active layer having a channel region on the substrate, forming an impurity-blocking mask covering the channel region and portions of the active layer outside the channel region adjacent the channel region, and doping impurities of a first conductivity type at a high density into portions of the active layer uncovered by the impurity-blocking mask to form impurity-doped regions in the active layer. The method further includes the steps of removing the impurity-blocking mask and thereafter performing a plasma treatment on the resultant structure using a plasma gas containing impurities of the first conductivity type to form LDD regions in the active layer between the channel region and the impurity-doped regions.
