Title: Thermal cvd/pecvd reactor and use for thermal chemical vapor deposition of silicon dioxide and in-situ multi-step planarized process
IPC: H01L21/316
Filed: 1987-12-18
Abstract: A high pressure, high throughput, single wafer, semiconductor processing reactor (10) is disclosed which is capable of thermal CVD, plasma-enhanced CVD, plasma-assisted etchback, plasma self-cleaning, and deposition topography modification by sputtering, either separately or as part of in-situ multiple step processing. The reactor includes cooperating arrays of interdigitated susceptor (16) and wafer fingers (20) which collectively remove the wafer (15) from a robot transfer blade (24) and position the wafer with variable, controlled, close parallel spacing between the wafer and the chamber gas inlet manifold (26) then return the wafer to the blade. A combined RF/gas feed-through device (36) protects against process gas leaks and applies RF energy to the gas inlet manifold without internal breakdown or deposition of the gas. The gas inlet manifold (26) is adapted for providing uniform gas flow over the wafer. Temperature-controlled internal and external manifold surfaces suppress condensation, premature reactions and decomposition and deposition on the external surfaces. The reactor also incorporates a uniform radial pumping gas system which enables uniform reactant gas flow across the wafer and directs purge gas flow downwardly and upwardly toward the periphery of the wafer for sweeping exhaust fases radially away from the wafer to prevent deposition outside the wafer and keep the chamber clean. The reactor provides uniform processing over a wide range of pressure including very high pressures. A low temperature CVD process for forming a highly conformal layer of silicon dioxide is also disclosed. The process uses very high chamber pressure and low temperature, and TEOS and ozone reactants. The low temperature CVD silicon dioxide deposition step is particularly useful for planarizing underlying stepped dielectric layers, either alone on in conjunction with a subsequent isotropic etch. A preferred in-situ multiple-step process for forming a planarized silicon dioxide layer uses (1) high rate silicon dioxide deposition at a low temperature and high pressure followed by (2) the deposition of the conformal silicon dioxide layer also at high pressure and low temperature, followed by (3) a high rate isotropic etch, preferably at low temperature and high pressure in the same reactor used for the two oxide deposition steps. Various combinations of the steps are disclosed for different applications, as is a preferred reactor self-cleaning step.

Title: Rear-vision mirror for auto-vehicles
IPC: G05B19/35
Filed: 1988-01-26
Abstract: The object of the invention is a rear-vision mirror for autovehicles, in which the mirror holder is angularly movable relatively to a housing (3) around a horizontal pivot axis (X-X) and around a vertical pivot axis (Y-Y) by means of two driving units (AX,AY) which are accomodated in the housing (3) for the mirror holder and are each associated with one of the said pivot axes. The said driving units (AX,AY) comprise each an electric motor (14) which by means of a mechanical transmission (16,15,17,18,21,20) drives a rack (13) arranged substantially at right angles with the mirror holder (1), which is articulatingly connected thereto (at 113) and is guided in the housing (3) for the mirror holder. A control device is provided which allows to move the mirror holder into the required position by having it angularly moved by means of the two electric motors (14) around the one and/or the other pivot axis (X-X, Y-Y), and which also allows to store one or more positions of the mirror holder and to have the same automatically moved into one or the other of these stored positions by means of a selecting respective control and with the aid of detectors (24) of the angular position of the mirror holder around each one of the two pivot axes (X-X, Y-Y). According to the invention, the detector of the angular position of the mirror holder in relation to each pivot axis (X-X, Y-Y) is in form of a potentiometer (24) the actuation of which is derived from a member (20) of the drive between the electric motor (14) and the rack (13) associated with the respective pivot axis, the rack (13) being not disengageably connected to the member (20) for actuating the potentiometer (24), while in the drive between the said member (20) for actuating the potentiometer (24) and the respective electric motor (14) a friction coupling (21) is interposed.

Title: Process for cooling hot pyrolysis gas
IPC: B01D5/00
Filed: 1988-06-23
Abstract: In a multi-stage cooling process for hot pyrolysis gas formed by degassing of plastic wastes or the like in a pyrolysis reactor, the hot pyrolysis gas is cooled by direct heat exchange in the first cooling stage (10) immediately downstream of the pyrolysis reactor. The cooling medium used here is a low-boiling pyrolysis oil which is obtained by condensation of pyrolysis gas in a cooling stage (32) which is located downstream of the first cooling stage. As a result, separate cooling and purifying measures for the pyrolysis oil are unnecessary. <IMAGE>

IPC: C07H13/06
Filed: 1989-04-15
Abstract: From a reaction mixture obtained by reaction of 
sucrose and a fatty acid alkyl ester in the presence of a 
catalyst, a purified sucrose fatty acid ester is prepared 
without using organic solvents for purification by adding 
water to the reaction mixture and subjecting the 
resulting aqueous solution to ultrafiltration, thereby 
removing the unreacted sucrose, the catalyst or a salt 
derived from the catalyst, and the volatile component 
used as the reaction medium together with water. A 
powder of the purified sucrose fatty acid ester is 
easily, economically and safely prepared by subjecting 
the aqueous solution remaining in the ultrafiltration to 
reverse osmosis and spray-drying the resulting 
concentrate.

Title: Method of making high density interconnects
IPC: H05K3/46
Filed: 1989-07-12
Abstract: A method of making a high density interconnect with supercon­
ductive lines is provided. A layer of high T c  superconductive 
material is deposited on an electrically insulative substrate 
layer (32) of closely matching crystal structure. The super­
conductive layer (30) is then photolithographically patterned 
to define part of an electrical interconnect circuit, and 
either selectively etched away or ion bombarded to destroy 
its superconductivity in noncircuit areas. Another layer (34) 
of insulative material is deposited over the superconductive 
lines thus formed, and via holes (38) are formed therein. 
The steps are then repeated for additional layers of supercon­
ductive material and insulative material until a complete 
interconnect is formed. The high T c  material is superconduc­
tive at 77 K and has orders of magnitude less attenuation 
than copper at the same temperature.

Title: Extended kraft cooking with white liquor added to wash circulation
Inventor: STROMBERG BERTIL
IPC: D21C9/16
Filed: 1991-05-22
Abstract: In the continuous kraft pulping of comminuted cellulosic fibrous material (e.g. wood chips) to produce paper pulp, viscosity for a given Kappa Number is significantly increased (e.g. at least about 20%) by adding kraft white liquor to the wash recirculation loop (38-40) in a continuous digester (19). Optimum results are obtained when kraft white liquor is also added to a recirculation loop (28-30) at a central portion of the digester, so that the majority of the digester has countercurrent flow between white liquor and cellulosic material. About 5-20% of the total white liquor necessary to effect kraft cooking is introduced in the wash circulation, and about 10-20% is introduced into the central portion recirculation. The temperature in the wash zone is maintained at about 140-175 DEG C. <IMAGE>
