Abstract
PURPOSE: To improve the heat radiating property of glass seal system by inserting a heat conductive heat sink between semiconductor pellet and bottom substrate.
CONSTITUTION: Connect pellet 4 to copper heat sink plate 2 by means of gold paste 3. Firmly affix the heat sink plate to ceramic plate 6 with high melting point glass 5 and seal cap 10 with low melting point glass 7. Portions 2a of heat sink plate 2 are exposed and because of these exposed portions, the heat of pellet is radiated effectively to reduce the thermal resistance to 70W80°C/W, thus enabling to increase the output extensively.
