TSMC's new highly integrated LED driver integrated circuit process
September 19, 2022
The epitaxial wafer manufacturer TSMC has gradually become clear in the layout of LEDs. On the (15th), it announced the BCD process for the production of LED drivers. It can produce high-voltage integrated LED driver integrated circuit products for customers and reduce the system's zero with high integration. The number of components.
TSMC said that this new BCD process features a working voltage range of 12 volts to 60 volts to support a wide range of LED applications, including backlights for LCD flat panel displays, LED displays, general lighting and automotive lighting. And the process spans multiple generations from 0.6 micron to 0.18 micron, and has several digital core modules to choose from, suitable for different digital control circuit gate density. In addition, the CyberShuttleTM shared test is available to support initial functional verification of the 0.25 micron and 0.18 micron processes.
The bill of materials for system products can be reduced by the multiple integration features provided by TSMC's new process. Not only strong high-voltage DMOS provides MOSFET switch integration, reducing the number of components, other components that can be integrated include: high-voltage dual-carrier transistors, high-voltage / high-precision capacitors, high-resistance polysilicon Zener diodes (Zener diode), etc., can also reduce the number of external components and significantly reduce the area of the board.
Director Liu Xinsheng of the Industrial Electronics Development Division of TSMC pointed out that the BCD process of the new LED driver is a very sophisticated technology for the integration of drive components. The related process design kits (PDKs) emphasize the highly accurate SPICE model. More convenience in chip design. The Mismatching Model also helps to improve the accuracy of current multi-channel LED driver designs.
TSMC announced the introduction of a modular BCD process to produce high-voltage integrated LED driver integrated circuit products that provide a 12-60 volt operating voltage range to support a wide range of LED applications, including backlighting for LCD flat panel displays.
