Abstract

The relationship between substrate materials and the deposition of diamond or graphitic soot was studied in the low-pressure synthesis of diamond. Electrocatalytic metals such as Fe, Ni, Rh, Pd, Pt, and Ir result in soot deposition while insulating materials such as Al2O3and SiO2result in diamond deposition. There exists a strong correlation between the electrocatalytic substrate materials and soot deposition. The substrate dependence of the deposition behavior is approached by the theory of charged clusters. The substrate dependence is suggested to be related to the charge-transfer rate at the substrate surface for charged clusters, which had formed in the gas phase. The evolution of soot and diamond is explained in terms of the floccula-tion and deflocculation behavior of colloid particles, respectively.

Abstract

This paper presents an Advanced Excimer Laser Annealing (AELA) process for large-sized OLED displays. Achieving good uniformity and performance characteristics of LTPS TFTs using cost-effective processes are important issues for the production of OLED displays. The AELA uses a conventional ELA system, XeCl laser, large optics and positioning stage, with improved processes and existing technology such as a selective crystallization function. The selective crystallization function of the AELA process has been optimized to obtain uniform microstructure of the crystallized Si films at the TFTs and interconnection region. Specifically, the 7/20 (W/L) TFTs via AELA processed Si films have mobility of 73.81 cm2/V-sec, threshold voltage of −2.07 V and sub-threshold swing of 0.40 V/dec. 55″ FHD OLED displays have been fabricated using the AELA process. The advantages and challenges of AELA technology will be further discussed. [ABSTRACT FROM AUTHOR]
