  • GENERAL PROCESS AND OPERATION SPECIFICATION

    • Process chamber is cleaned beforehand with an O2-based plasma. • The etching gas (SF6, CHF3) is gradually introduced into the plasma. Begin the process with a 15:00+ min O2 clean, then decrease the chamber temperature to your desired value.

    Figure 1. Effects of process parameters on the Si etch rate. When testing the effects of one parameter on the rate, the other two are kept constant. It has previously been determined that the effect of O2 on the SF6 plasma is a dramatic increase in the F atom concentration and a subsequent decrease in lateral etching [5].

  • The CORE Sequence: A Nanoscale Fluorocarbon-Free Silicon

    Jan 08, 2020 · This study focuses on the development of a fluorocarbon-free directional silicon etching process, called CORE (Clear, Oxidize, Remove, and Etch) in which a switching sequence of SF 6 and O 2 is operated at room temperature. This distinguishes it from the old-fashioned room temperature and cryogenic mixed RIE processes as CORE enables a higher selectivity, creates pattern independency of etching profiles and works excellent at room temperature.

  • Myth About SF6 Gas In Electrical Equipment

    Where is SF6 used? The following applications are known. For some of these most probably you haven’t heard of. For sound insulation in windows, In vehicle tyres, Is SF6 a health hazard? Pure SF6 is physiologically completely harmless for humans and animals. It’s even used in medical diagnostic. Due to its weight it might displace the oxygen in the air, if large quantities are concentrating in deeper and non ventilated places. Is SF6 harmful for the environment? It has no ecotoxic potential, it does not deplete ozone. Due to its high global warming potential of 22.200 (*) it may contribute to the man made greenhouse-effect, if it is released into the atmosphere. What is the overall contribution of SF6 used in the electrical equipment to the greenhouse effect? Less than 0,1 % ( see CAPIEL) and CIGRE). In an Ecofys study the contribution to the greenhouse effect in Europe is estimated to 0.05 % (*).
