Title: Detecting liquid flow in a pipe subjected to freeze blocking or heating
Inventor: HALLETT TREVOR
IPC: G01F1/684
Filed: 1996-06-10
Abstract: A method of detecting liquid flow in a pipe 20 subjected to freeze blocking or heating comprises determining by means of temperature probes 10, 12 the temperature upstream and downstream of the section 22 of the pipe 20 at which heat is added to or removed from the liquid. The difference between the two temperatures indicates whether the liquid in the pipe is flowing and, if so, in which direction. The method may also be used to determine the strength of any liquid flow. If liquid is flowing slowly through the section 22 to be, for example, frozen, it will become cooled, such that the probe 12 downstream of the section 22 will record a lower temperature than the probe 10 which is positioned upstream. Therefore, an immediate indication of liquid flow and its direction can be obtained. The disclosed method is relatively cheap and simple, but highly effective for providing an indication of liquid flow and the direction of such flow, for pipe freezing or heating techniques.

Title: Method of forming a tantalum oxide containing capacitor
Inventor: KIM SUNG-TAE
IPC: H01L21/02
Filed: 1998-12-04
Abstract: A method of forming a tantalum oxide containing capacitor which improves the Ta<SB>2</SB>O<SB>5</SB> film's properties, and includes providing a plasma silicon nitride film having a thickness of 20 100 angstroms, sufficient to prevent oxidation of a lower capacitor electrode, by a plasma nitridation process using a reactant gas during the step of preprocessing the surface of the lower capacitor electrode. The plasma silicon nitride film is formed by nitrifying a surface portion of the lower capacitor electrode by means of excitation of a reactant gas with a plasma. The plasma nitridation process is effective to form a sufficiently thick silicon nitride film on the lower capacitor electrode and anneal the resulting substrate in the same process chamber. Also, the method is applicable to a more simplified annealing mechanism, providing cost savings in the manufacture of DRAM devices, in the form of an ozone annealing process using thermal energy of more than about 400{C. In the ozone annealing process, the thermal energy is generated by heating a susceptor where wafers are placed.
