標題 Highly uniform SOI fabrication by applying voltage during KOH etching of bonded wafers
掲載誌名 IEEE International SOI Conference

概要 A new technique is presented for thinning SOI bonded wafer by applying voltage during KOH etching. Excellent SOI thickness variation of less than ±μm is achieved by etching wafers in KOH and applying voltage between the supporting substrate and the electrode in the etchant. Higher uniformity can also be achieved by refining the etching equipment and controlling the chemical reaction at the surface during etching. This technique is useful in providing low-cost bonded SOI wafers by simplifying conventional thinning processes.
