  • Method of manufacturing a semiconductor device for surface mounting suitable for comparatively high voltages, and such a semiconductor device
    Patent number: 5930653
    Abstract: The invention relates to a method of manufacturing a semiconductor device whereby an upper side of a wafer of semiconductor material (12) is provided with semiconductor elements in passivated mesa structures (2), which semiconductor elements are provided each with a connection electrode (7') in that according to the invention conductive contact bodies (3') are provided on upper sides (7) of the mesa structures (2), and an insulating material (18) is provided in spaces (17) between the contact bodies, whereupon the wafer (1) is split up into individual semiconductor bodies (10) which comprise passivated mesa structures (2) and contact bodies (3') surrounded by insulation. The contact bodies (3') have dimensions such that the semiconductor bodies (10) are suitable for surface mounting. The semiconductor devices made by the method according to the invention are resistant to comparatively high voltages between the connection electrodes (7', 4).
