Product Overview

ONC25: 0.25 µm Process Technology

Product Description
The ONC25 process family from ON Semiconductor is an ideal 0.25 mm low cost solution to mixed-signal designs. ONC25 is designed for 2.5, 3.3, 5.0 V single-gate or 2.5/3.3 V or 2.5/5 V dual-gate operation with high-performance/low-power and mixed-signal 2.5 V or 5.0 V digital libraries, and mixed-signal features such as MIM capacitors, Schottky diodes, zener diodes, high resistivity poly, deep Nwell for Pwell isolation and under Nwell in the digital blocks to optimize packing density. ONC25 provides the flexibility to implement a variety of mixed-signal applications.

Features

  • Gate Oxide voltages: 2.5, 3.3, 5.0 V
  • 2 to 5 metal layers
  • Top metal option thicknesses: 1.0, 1.5, 3.0 µm
  • MIM capacitor: 1.0 fF/µm² located below top metal
  • Schottky diodes (planned)
  • Zener diodes: 5.15, 5.5, 6.2 and 7.4 V
  • High sheet resistance (1.5 kW) polysilicon resistor
  • Low temperature coefficient polysilicon resistor
  • Salicide process with optional blocking
  • Deep Nwell for Pwell isolation, NPNs, and also may be used under Nwell in the digital blocks to optimize packing density
