    摘要: By providing appropriate TFT structures arranged in various circuits of the semiconductor device in response to the functions required by the circuits, it is made possible to improve the operating performances and the reliability of a semiconductor device, reduce power consumption as well as realizing reduced manufacturing cost and increase in yield by lessening the number of processing steps. An LDD region of a TFT is formed to have a concentration gradient of an impurity element for controlling conductivity which becomes higher as the distance from a drain region decreases. In order to form such an LDD region having a concentration gradient of an impurity element, the present invention uses a method in which a gate electrode having a taper portion is provided to thereby dope an ionized impurity element for controlling conductivity accelerated in the electric field so that it penetrates through the gate electrode and a gate insulating film into a semiconductor layer.

    摘要: In the fabrication of semiconductor devices such as active matrix displays, the need to pattern resist masks in photolithography increases the number of steps in the fabrication process and the time required to complete them and consequently represents a substantial cost. This invention provides a method for forming an impurity region in a semiconductor layer 303 by doping an impurity element into the semiconductor layer self-aligningly using as a mask the upper layer (a second conducting film 306) of a gate electrode formed in two layers. The impurity element is doped into the semiconductor layer through the lower layer of the gate electrode (a first conducting film 305), and through a gate insulating film 304. By this means, an LDD region 313 of a GOLD structure is formed in the semiconductor layer 303.

    摘要: TFTs arranged in various circuits have structures that are suited for circuit functions, in order to improve operation characteristics and reliability of the semiconductor device, to lower consumption of electric power, to decrease the number of steps, to lower the cost of production and to improve the yield. The gradient of concentration of impurity element for controlling the conduction type in the LDD regions 622 and 623 of the TFT is such that the concentration increases toward the drain region. For this purpose, a tapered gate electrode 607 and a tapered gate-insulating film 605 are formed, and the ionized impurity element for controlling the conduction type is added to the semiconductor layer through the gate-insulating film 605.
