Abstract
An integrated circuit device ( ) comprises a semiconductor die ( ) and an optical signal emitting diode ( ) for communicating an optical signal, such as a clock or trigger signal, to individual circuits on the die ( ). Each circuit includes a photosensitive active device implemented on the die for converting the received optical signal to an electronic signal for clocking or triggering a local circuit (e.g., a data storage register). Translucent material ( ) encapsulates the emitter diode ( ) and the die ( ). The optically communicated signal has very low skew, which is independent of the topology of the die ( ).
