The RCA clean is a standard set of wafer cleaning steps which need to be performed before high-temperature processing steps (oxidation, diffusion, CVD) of silicon wafers in semiconductor manufacturing.
The best -known system of this type is known as the “RCA cleaning proces s,” which will be described in this paper. It is used for cleaning silicon wafers in the initial stages of processing.
The RCA clean is a standard set of wafer cleaning steps which need to be performed before high-temperature processing steps (oxidation, diffusion, CVD) of silicon wafers in semiconductor manufacturing. The RCA cleaning process consists of a SC-1 clean step, an oxide strip step, and a SC-2 clean step.
RCA-1 clean is used to remove organic residues from silicon wafers. In the process, it oxidizes the silicon and leaves a thin oxide on the surface of the wafer, which should be removed if a pure silicon surface is desired. This is a level-1 process and requires basic INRF safety certification.
Feb 9, 2021 · RCA Organic clean (or Standard Clean 1/ SC1) is used to remove organic contaminants from the surface of the wafers. This is the same as the organic clean for pre-furnace clean. The chemical mixture ratio is 1:1:6 H 2 O 2 :NH 4 OH:H 2 O, and is heated to 85oC.
Jan 1, 2018 · A roadmap for simplifying the cleaning process from RCA clean to IMEC Clean and eventually to single-wafer wet clean is outlined in Fig. 1.4-4 as a guide [165]. The IMEC Clean concept is based on a two-step cleaning approach and is illustrated in Fig. 1.4-5 .
The famous RCA-1 clean (sometimes called “standard clean-1”, SC-1), developed by Werner Kern at RCA laboratories in the late 1960’s, is a procedure for removing organic residue and films from silicon wafers.
The work is divided into three sections. The first six chapters address fundamental processes in chemical cleaning. Chapter 1 examines surface and colloid chemistry in clean-ing, and Chapters 2 and 3 describe the chemistries of cleaning and etching pro-cesses. Chapter 4 details the surface phenomenon of cleaning.
RCA WAFER CLEAN SOP Revised April 2020 Purpose: To remove all foreign matter from the surface of the silicon wafers (dust, oil, silicon dust, etc.) prior to processing. This procedure entails the use of three solutions, of which, two contain hydrogen peroxide (H 2 O 2) to remove residual organic, ionic and metallic contamination left behind
The famous RCA-2 clean (sometimes called “standard clean-2”, SC-2), developed by Werner Kern at RCA laboratories in the late 1960’s, is a procedure for removing metal ions from silicon wafers. The decontamination works based on sequential oxidative desorption and complexing with H2O2-HCl-H2O (RCA-2).
