Embodiment Construction
[0041] In the embodiment of the present invention, when forming the n+ region and n- region of the LTPS TFF, the above-mentioned n+ region and n- region are formed by using the photoresist defining the gate pattern and the gate target pattern as shields respectively. The resist precision and gate target pattern precision are controllable, so that the precision of the n-region can meet the precise control of the LDD structure size of the low-temperature polysilicon thin film transistor, and simplify the manufacturing process of the LTPS TFF.
[0042] Before the method of the embodiment of the present invention is described in detail, several process flows involved in the embodiment of the present invention are briefly described, so as to better understand the embodiment of the present invention.
[0043] In semiconductor manufacturing, it is necessary to use selected images, graphics or objects to block the film layer to be processed in order to control the active area of etch...
