Abstract

1,110,654. Planar semiconductor devices. STANDARD TELEPHONES & CABLES Ltd. 22 Dec., 1966 [24 Dec., 1965], No. 54764/ 65. Heading H1K. In a planar semi-conductor device a metallic layer including an impurity of one conductivity type is alloyed to form a junction surrounding a rectifying junction in a semi-conductor body of the one conductivity type. An aperture is etched in a SiO 2 layer 1 on a p-type Ge body 2 and Sb diffused in to give a base region 4. Further apertures are etched in layer 1 to give a rectangular frame surrounding the base region and a layer of A1 evaporated over the body which is then masked and etched to leave Al in the frame and a rectangular region on the base region. The Al is alloyed to give an emitter region 6 and a ring junction 5. A layer of glass 8 is then deposited on the device and etched to expose the base region. A coating of Ag-Au-Sb is applied, masked and etched to leave base contact 11. The emitter region 6 is then exposed and the slice baked in vacuo at 350‹ C. An Al layer is evaporated on to the slide at 200‹ C. and the excess of Al etched away to leave contacts 9 and 10. A plurality of devices may be formed in one slice and subsequently divided.
