Native Oxide Removal System

Model:RISE-300

The system is designed for the precise removal of native oxide in advanced semiconductor fabrication, supporting applications such as LSI deep-contact bottoms and other narrow, high-aspect-ratio pattern structures.

This system is compatible with 300mm wafers.

Features

  • Dry etching with excellent uniformity (< ±5% per batch), enabling the highly reproducible removal of persistent native oxide layers, such as those on LSI deep-contact bottoms.
  • Damage-free processing achieved through remote plasma and low-temperature operation.
  • Reduces self-aligned contact resistance to 50% of conventional wet processes.
  • Batch system capable of processing up to 50 × 300mm wafers per batch, ensuring high throughput and low Cost of Ownership (CoO).
  • The design of the RISE-300 prioritizes ease of maintenance.

Applications

  • Pre-cleaning for self-aligned contact (SAC) formation.
  • Pre-cleaning for capacitor formation.
  • Pre-cleaning for epitaxial growth.
