A silicon layer may be formed to cover the trench and original surface of the substrate before the former deposition, or to cover a part of the trench and original surface of the substrate after the former etch back and before the later deposition, to serve as a stop layer for the planarization process. Voids existing within the isolation material layer can be exposed or removed by partially etching the isolation material layer by the former etch back. The later deposition can be performed with a less aspect ratio to avoid forming voids.

Abstract: Synthetic processes for preparing luminescent iridium complexes and precursors thereof are provided. The method employs water as the reaction solvent to prepare luminescent iridium complexes in two different ways. In the first way, a precursor [Ir2(C11NR8)4I2] (Formula I) is prepared from one of IrCl3, M3IrCl6 (M=Li, Na, K) and [Ir2(C11NR8)4Cl2], and then the precursor [Ir2(C11NR8)4I2] is converted into one of the two luminescent iridium isomeric complexes [Ir(C11NR8)2(C11NR?8)] (Formula II). In the second way, a metal complex IrCl3 or M3IrCl6 (M=Li, Na, K), HC11NR8 and a base are converted selectively into one of the two iridium isomeric complexes [Ir(C11NR8)3] (Formula VIII). Herein, R and R? are defined the same as the specification.
