Abstract
An electronic component (10) for aligning a light transmitting structure (19) such as an optical fiber or a waveguide, includes a semiconductor substrate (11) which contains or supports at least one semiconductor device (12). To provide electrical isolation and mechanical protection for the semiconductor device (12), a passivation layer (25) is disposed over the semiconductor substrate (11). At least one alignment feature (14) for the light transmitting structure (19) is provided over the passivation layer (25) and over the semiconductor device (12). The alignment feature (14) is manufactured simultaneously during a flip chip bump process which eliminates the necessity for extra processing steps while providing additional alignment functionality.
