Abstract
874,801. Semi-conductor devices. PHILIPS ELECTRICAL INDUSTRIES Ltd. Feb. 28, 1958 [March 4, 1957], No. 6548/58. Class 37. A semi-conductor device comprises a semi-conductor body containing a rectifying junction and provided with at least two contacts which is embedded in a good heatconducting mixture of an insulating binder and crystalline silicon carbide. In the embodiment a transistor 1 attached to conductors 2 sealed through a glass lid 3 is placed in a viscous mixture, consisting of 40 c.c. of a polymerized methyl siloxane and 60 grams of crystalline silicon carbide, contained in glass tube 4. The lid is then sealed to the tube and the viscous mixture compacted by centrifuging. Since silicon carbide is not an insulator the transistor and associated conductors are coated with a thin layer of insulating lacquer prior to their insertion in the mixture. Conduction of heat to the transistor via the conductors 2 is prevented by the glass bead 6 which serves as a heat sink. A crystal diode may be incorporated in the above assembly instead of a transistor. In an alternative form of the invention the semi-conductor body is merely coated with a mixture of a hardenable insulating binder and crystalline silicon carbide.
