    • A method for forming a thin film transistor (TFT), a related TFT, an array substrate, and a display apparatus are provided. The method comprises: forming a pattern of an active layer (02) on a base substrate (01) and insulated from a gate electrode (06); forming a first initial ohmic contacting layer (03) and a second initial ohmic contacting layer (04) on the active layer (02); forming a source electrode (08) on the first initial ohmic contacting layer (03), and a drain electrode (09) on the second initial ohmic contacting layer (04); and performing a heating treatment to the base substrate (01) having the source electrode (08) and the drain electrode (09) thereon, such that metal atoms in the source electrode (08) diffuse to the first initial ohmic contacting layer (03) to form a first ohmic contacting layer (10), and metal atoms in the drain electrode (09) diffuse to the second initial ohmic contacting layer (04) to form a second ohmic contacting layer (11).
    • 提供了一种用于形成薄膜晶体管(TFT),相关TFT,阵列基板和显示装置的方法。 该方法包括:在基础衬底(01)上形成有源层(02)的图案并与栅电极(06)绝缘; 在有源层(02)上形成第一初始欧姆接触层(03)和第二初始欧姆接触层(04); 在所述第一初始欧姆接触层(03)上形成源电极(08),以及在所述第二初始欧姆接触层(04)上形成漏电极(09); 并对其上具有源电极(08)和漏电极(09)的基础基板(01)进行加热处理,使得源电极(08)中的金属原子扩散到第一初始欧姆接触层(03) 以形成第一欧姆接触层(10),并且漏电极(09)中的金属原子扩散到第二初始欧姆接触层(04)以形成第二欧姆接触层(11)
