    Abstract

    The production of detached porous silicon (PS) layers for layer transfer (LT) has been investigated. Electrochemical anodisation (ECA) studies of monocrystalline silicon (mono-Si) wafers in a hydrofluoric acid/ethanol/ deionised (DI) water solution showed that porosity can be controlled by controlling current density during ECA. Double layered PS layers consisting of low (26-5%) and high (86-3%) porosity layers were formed by ECA at 1-5mAcm -2 and 100 mA cm-2 for etching times of 10 min and 10 sec respectively. These PS layers are considered viable for LT substrate technology.
