Title: A semiconductor device and method of manufacturing same
IPC: H01L21/28
Filed: 1980-02-29
Abstract: The semiconductor device includes a layer (30) which is impervious to steam and oxygen e.g. silicon nitride (Si3N4) beneath a phosphosilicate glass (PSG) layer (32). The presence of the nitride layer during the step of 'flowing' and any step of "reflowing" the glass prevents oxidation of underlying silicon regions thus enabling these steps to be carried out in an atmosphere containing steam, which in turn permits use of a PSG layer containing less than 7% phosphorous by weight to give improved reliability in devices where aluminium tracks (34) run over the glass, or permits the use of lower temperatures in the process. <IMAGE>

Patent GB-2065330-A (GB)
Title: Fluid Temperature Control System
IPC: G05D23/13
Filed: 1980-11-18
Abstract: The system provides a supply fluid at a select temperature by warming or cooling a first fluid with a controlled flow of a second fluid. The control of the second fluid flow is achieved by a modulation valve 30 adjustable in response to the pressure of a supply of servo fluid which is itself adjusted via a flapper-controlled bleed 90 in response to the temperature, sensed at 55, of the supply fluid. The adjustment of the servo fluid pressure by the control system is such that the change in servo fluid pressure from a steady state condition is initially great, diminishing with time to a lesser, steady state value, thereby enhancing the transient response of the control system. This is achieved by a diaphragm 150 linked to the flapper and responsive to the pressure in a chamber 140 communicated with the servo fluid via restriction 145. <IMAGE>
