Manufacturing Insights
Essential success factors and key elements in display manufacturing explained.
A key point for success in display manufacturing.
ICs and TFT-based displays are the 2 largest semiconductor industries.
The large-area manufacture technology is the key element to the success.
For ICs, the focused is on increasing the device density in a chip, e.g., minimizing the demension or building stacked structures.
For TFTs, the focus is on maximizing display areas.
TFT on Glass Process vs. IC on Si Process
This image compares TFT and IC technologies essential for TFT LED displays, highlighting the differences in manufacturing processes for display driving (TFT) and high-performance processing (IC).
TFT on Glass (Left Image):
Formed on glass substrates for pixel switching.
Ensures fast and stable display by controlling pixel ON/OFF.
Uses low-temperature processes for large, thin, and lightweight displays.
Materials:
a-Si TFT: Low cost, suitable for large areas but slower response.
Oxide TFT: High mobility for fast driving and high resolution, suitable for OLED and Micro-LED.
IC on Si (Right Image):
Formed on silicon substrates for high-speed processing and control.
Essential for high-performance displays.
Utilizes advanced processes for miniaturization and high integration.
Technology:
7nm, 5nm Processes: High performance with low power consumption.
Challenges & Solutions: Addressing leakage currents with new transistor structures like FinFET and GAA.
This comparison clarifies the differences in application, structure, and manufacturing, providing key insights for future display and semiconductor technology advancements.
