Title: Doped polycrystalline silicon layers for semiconductor devices
Inventor: TINO CHRISTOPHER JULIUS
IPC: H01L21/3205
Filed: 1987-12-15
Abstract: An improved phosphorus doped polycrystalline silicon layer for semiconductor devices is deposited in the amorphous state by low pressure chemical vapor deposition in an isothermal reactor (Fig 2) from a gas mixture containing an increased amount of phosphine over the amount conventionally used. The gas proportions are 16 x 10<-4> to 17 x 10<-4> parts by volume of phosphine to each part by volume of silane. After deposition the layer is annealed to convert it to the polycrystalline state. A layer formed by this method is characterized by exceptional uniformity of doping, enlarged grain size, significantly increased electrical conductivity and improved radiation hardness in comparison to layers formed by conventional processes. <IMAGE>

Title: Pulp manufacture
Inventor: FONGEN SIGURD
IPC: B01J8/00
Filed: 1988-02-03
Abstract: In a process for digesting plant and wood fibers or for delignification, optinally with preceding deinking, of fibers from chemical or mechanical pulps, optionally with succeeding bleaching, the fibrous raw material is digested or delignified in an alkaline pumpable slurry in a pressurized tube system and conducted therethrough by the use of pulp pumps. On its way through the pressurized tube system the pulp is repeatedly dewatered and after each dewatering, save the last one, is rediluted with pressed out process liquor recycled from a downstream dewatering step and/or from a downstream pumping stage of the process. While being conducted through the pressurized tube system the pulp is subjected to stepwise increasing pressure, the pressure increase being caused by the pulp pumps. An apparatus for use in carrying out the process comprises an inner perforated tube (83) surrounded by an outer tube (85) which at its ends is sealed against the inner tube (83). The outer tube (85) which is capable of enduring high pressures is provided with one or more tubes (86) for receiving process liquor pressed out from the pulp through the perforations of the inner tube (83).
