Abstract
A semiconductor element including an electrically insulating substrate, semiconductor layers including first and second semiconductor layers of different conduction types and formed on the electrically insulating substrate, a first electrode formed on the first semiconductor layer, and a second electrode formed on the second semiconductor layer revealed by etching at least the first semiconductor layer, wherein a die-bonding electrode is formed on a side surface of the second electrode, on a side surface of the second semiconductor layer and on a region of from a side surface to a bottom surface of the electrically insulating substrate. Metal-metal contact is formed between the die-bonding electrode and the side surface of the second electrode, so that low-resistance contact is obtained here.
