Abstract
A light emitting device includes an LED chip fixed to an electrode body via a conductive layer of In or an In alloy. The conductive layer is in ohmic-contact with an n-type ZnSe crystal substrate of the LED chip. To make the device, In or an In alloy is melted on the electrode body, the ZnSe substrate is placed directly on the melted In or In alloy and then subjected to at least one of vibration and pressure to achieve a good bond and ohmic contact between the In or In alloy and the ZnSe substrate.
