Abstract
A stress sensitive semiconductor unit comprising means for supporting a very long elongated cylindrical support member having a stress sensitive semiconductor die bonded to one end thereof, a plurality of metal elongated terminal pins held in rigid hermetically sealed insulative relationship with said header, first and second insulative spacers having central bores sized larger than the outer diameter of the glass tubular member and positioned in axial proximity to one another with the first spacer being abutted against the header and with the second spacer being sized so that the outer axial end thereof is substantially in planer register with the active face of the semiconductor die, the ends of the terminal pins being mechanically and electrically connected to conductive areas or portions on the face of the second spacer.
