LTPS is a Si-based material that consists of numerous crystalline silicon clusters of 0.3 up to several microns. In the semiconductor manufacturing industries, poly-silicon is usually formed by solid phase crystallization (SPC) which involves annealing at a temperature above 900 degrees.

However, since the deformation temperature of glass is only 650 degrees, the SPC method is not suitable for the flat panel display manufacturing industries. As a result, the LTPS technology is a poly-silicone technology dedicated to applications for flat panel displays.

It is said that the 6G LTPS TFT-LCD technology aims at satisfying the growing demand of high-end, small and medium-sized panels, in an attempt to change the current situation: highly relying on importing.

More than one newspapers and news websites reported that Foxconn will invest the 6G low-temperature polysilicon (LTPS) TFT-LCD plant in Zhengzhou, China.

Hon Hai responded to it on November 9 by filing a statement with the Taiwan Stock Exchange, saying “ the investment belongs to our strategic partner Ying Hui, if there is any planned investment, the company will propose the plan to its board for approval.”
