The triple voltage process consists of an innovative zero layer CMOS transistor design embeddable in the standard 1.8/5V and 1.8/3.3V CMOS processes. The new CMOS transistors have a maximum gate voltage of 7V and maximum drain voltage of 10V in operation with breakdown voltage of over 17V. This process is fully compatible with the standard CMOS process and does not require process changes or additional process steps.
On-resistance of the new transistors is lower than conventional high voltage transistors, including EDMOS and LDMOS that usually incorporate high resistive paths for carriers toward drain contact. Low on-resistance and high breakdown voltage enable IC design flexibility for on-chip integration of analog switches and power amplifiers for high performance mixed signal applications.
TJ Lee, senior vice president and general manager of MagnaChip's Corporate and SMS Engineering stated, "We are pleased to offer a zero layer 10V triple voltage CMOS process for mixed signal applications. This is a big step towards achieving leadership with our premium mixed signal processes, including triple gate oxide and ultra low noise processes already in production. We will continue to provide process solutions for the application specific needs of our foundry customers."
