0.18µm 25V BCD  

CSMC's 0.18µm BCD process is the general platform to the high-level power management products, especially to the digital power segment.
The current process development is focusing on 1.8V, 5V and 25V rating voltage, which indicates the operation voltage.
The core devices are compatible with 0.18µm popular logic and mix-mode process, and the relevant library, IP are compatible in this platform. 
  

- Base on the 0.18µm logic baseline process to embed the HV relevant layers

- Offer comprehensive and complete devices, includes 1.8V Core, 3.3V or 5V IO, LDNMOS 25V/5V or 25V/3.3V, N/P-channel 25V symmetric/asymmetric MOSFET, high performance vertical NPN, diode, NJET
- Implement the RESURF structure to let LDMOS be better at low Rdson and BV trade-off 

- 1P6M architecture
- Triple trenches for HV and LV devices
- Dual-gate oxide
- Co-silicide
- Al backend with low-K FSG material 
  

- Driver ICs
