Title: Process for the production of polyether polyols
Inventor: HOFMANN JORG
IPC: C08G65/28
Filed: 1998-01-08
Granted: 2001-12-01
Abstract: Polyether polyols are produced by acid-catalyzed polyaddition of alkylene oxides to starter compounds having active hydrogen atoms. Perfluoroalkylsulfonic acid salts of metals from group IIIA of the periodic table of elements (corresponding to the IUPAC Convention of 1970) are used as the catalyst. The polyaddition reaction is carried out at a temperature of from 40 to 200 DEG C at normal pressure or pressures from 0 to 20 mbar (absolute). An inert organic solvent may optionally be included in the reaction mixture. Substantially all of the catalyst is removed from the polyether polyol-containing reaction mixture by lowering the temperature and/or by addition of a precipitating agent and/or by extraction with water. If desired, the recovered catalyst may be used in subsequent polyaddition reactions.

Title: Two-stage etching method to form self-aligned contact
Inventor: CHEN BI-LIN
IPC: H01L21/768
Filed: 1999-01-26
Granted: 2003-08-11
Abstract: The present invention is a two-stage etching method to form self-aligned contact, which is a method mainly using a silicon nitride gate sidewall structure and a silicon nitride gate cap to realize a self-aligned contact in MOSFET devices, especially for the application of fabricating DRAM. The bit line contact is formed between two adjacent word lines, each word line having a nitride sidewall structure. The etching of contact needs to have a high oxygen/nitrogen etching selectivity. The etchant of the prior art relies on forming a polymer material on the silicon nitride surface to increase the oxygen/nitrogen etching selectivity. However, the contact width is less than 0.35 mum in high-density DRAM processes. The polymer generated to obtain a higher etching selectivity will seal the contact before it is completely etched, which results in an open-circuit or a high resistance contact that is not acceptable. On the other hand, if the etchant is adjusted to generate too little polymer, the nitride cap and sidewall structure will become thin or over-etched to short-circuit the gate and the source/drain. The present invention discloses a two-stage etching step to etch the contact with a high etching selectivity in the beginning. When the contact becomes narrow, the forming rate of polymer decreases to avoid the connection of polymer and ensures that the insulator in the contact area can be removed. The present method demonstrates a continuous etching step and removal of polymer and photoresist with the same RIE tool.

Title: Pressure-compensated liquid dispenser
Inventor: PARSONS NATAN E
IPC: A47K5/12
Filed: 1999-12-23
Granted: 2001-05-16
Abstract: An automatic soap dispenser (10) includes a disposable soap container including a dispensing mechanism (20) in which walls of an interior chamber (56) cooperate with a diaphragm (62) and a plunger (66) to form a transit chamber (64), which is resiliently expandable against the force of a spring (80). When a solenoid (58) permits the diaphragm (62) to move away from the outlet of a passage (50) in a flow path from the interior of a pressurized reservoir (18) to the expandable transit chamber (64), travel of the plunger (66) permits the transit chamber (64)'s pressure-relieving outlet opening to expand so that the pressure within the transit chamber (64) is determined predominantly by the force of the spring (80) rather than by the pressure within the reservoir (18). The velocity of the liquid dispensed from the transit chamber (64) through the dispensing mechanism's spout (16) is therefore relatively independent of the pressure within the reservoir (18).
