ABSTRACT:
A printed-circuit construction having an EPROM IC chip on the surface of an insulating baseboard. The insulating baseboard has on a primary surface a printed circuit pattern and a semiconductor chip support region. The EPROM IC chip is fixed to the semiconductor chip support region of the insulating baseboard. Thin metal wires connect electrodes of the EPROM IC chip to the printed circuit pattern. A cap is fixed to the primary surface of the insulating baseboard in covering relation to a surface of the EPROM IC chip and the thin metal wires. The cap is made of a material capable of transmitting ultraviolet radiation therethrough.
