Patent number: 4481706Abstract: A process is provided for manufacturing bi-polar transistors integrated on silicon. To form transistors of very small dimensions, a layer of polycrystalline silicon is deposited (after a localized oxidization step) which is etched and which is doped so as to serve as doping source for P.sup.+ extrinsic base regions of the transistor. After doping of the P intrinsic base, the oxide and/or nitride is then deposited at low pressure which is implanted with an impurity facilitating dissolution thereof. On the vertical walls of the polycrystalline silicon around the base, the nitride is not dissolved. Elsewhere it is easily dissolved. Advantage is taken of the oxide or nitride thickness which remains to form by diffusion of an N.sup.+ emitter region which will not extend laterally as far as the P.sup.+ type extrinsic base but which will allow to remain an intrinsic base of very small thickness. The emitter diffusion may take place through a second polycrystalline silicon layer.Type: GrantFiled: June 25, 1982Date of Patent: November 13, 1984Assignee: Thomson-CSFInventor: Marcel Roche

The glass sealant is applied to the substrate in the form of a paste which thereafter is fired at high temperature and cooled to produce a smooth glass coating. With the cover in place on the substrate, the glass coating is remelted by heat developed by infra-red radiation impinging on all sides of the package structure from heaters in an infra-red furnace. A reflective shield on top of the cover reduces the inflow of heat through that surface, and a heat sink beneath the substrate removes heat, thereby to reduce the temperature rise experienced by circuit elements in the package interior.Type: GrantFiled: January 18, 1982Date of Patent: November 13, 1984Assignee: Analog Devices, Inc.Inventors: Delip R. Bokil, Tanjore R. Narasimhan
