Title: Process for the preparation of urea
Inventor: KEES JONCKERS
IPC: C07C273/04
Filed: 1985-03-15
Abstract: A process for the preparation of urea in which a carbamate- and free ammonia-containing urea synthesis solution is formed from carbon dioxide and excess ammonia in a synthesis zone at a pressure of 125-350 bar, at least a portion of the carbamate present in the urea synthesis solution is decomposed in a stripping zone at the pressure of the synthesis zone or at lower pressure by heat supply and countercurrent contact with a stripping gas, the carbamate decomposition products, together with a portion of the excess ammonia and the stripping gas, are removed from the stripping zone as a gas mixture, at least a portion of the gas mixture obtained is condensed in a condensation zone and the stripped urea synthesis solution is processed into a urea solution or solid urea. The process is characterized in that in the condensation zone also at least 30% of the equilibrium amount of urea achievable under the reaction conditions is allowed to form and the carbamate- and urea-containing mixture is supplied to the synthesis zone. By preference, urea formation is continued until 50-80 %, of the way to the equilibrium has been covered.

Title: Heat treatment method for silicon wafer
Inventor: YAMAMOTO MASAHIKO
IPC: H01L21/324
Filed: 1995-11-22
Granted: 1999-07-01
Abstract: The wafer after hydrogen treatment will reduce its mechanical strength. The invention provides a heat treatment after the hydrogen treatment so as to increase the mechanical strength of wafer and maintain all the properties of hydrogen treatment and increase oxygen concentration around the surface of wafer. The hydrogen-treated wafer is heat treated under 1100 degree C for two hours while oxygen is guided around the surface of wafer. The oxygen concentration decreases gradually from the surface to the depth about 3 to 4 micrometer and beyond this point it increase again till it reaches the internal oxygen concentration. Dislocations are produced by pressing the wafer and increased by the heat treatment. The propagation of the dislocations are detected and it is approximately 1/10 of that in hydrogen-treated wafer. By the heat treatment method proposed here, the wafer can have the same regional mechanical strength as before the hydrogen processing.

Granted: 2000-05-01
Abstract: A method for improving the etch back uniformity of a SOG layer by removing an etch back resistant polymer which builds up on the SOG layer during the etch back process. According to the present invention, a first insulation layer and a SOG layer are formed on a substrate. The SOG layer is partially etched back in a fluorocarbon containing plasma which forms a polymer residue on the SOG layer surface. The SOG layer is then treated in situ with an oxygen containing plasma to remove any of the etch resistant polymer residue on the SOG layer surface. The above in situ etch and oxygen containing plasma treatment of the spin-on glass layer are repeated until the SOG layer is etched back to the desired thickness.

Granted: 1999-08-21
Abstract: A kind of lead frame which is to add support belt with inner lead and suspended lead. The ends of support belts are overlapped on suspended lead and the neighborhood so that they are rectangular annularity. Because the support belt is L-shape, when the central end locates at the suspended lead and its neighborhood, only two overlapped portion of support belts are at suspended lead. Therefore, the number of correct arrangement of overlapped portion is reduced, and the L-shape support belt can be produced more efficiently from the material of support belt.
