  • Publication number: 20240141546
    Abstract: A method for evaluating a quartz glass crucible constituted by an outer layer formed of an opaque quartz glass containing a bubble, and an inner layer formed of a transparent quartz glass. The method includes steps of preparing a quartz glass crucible to be evaluated, irradiating the quartz glass crucible to be evaluated with ultraviolet rays as an excitation light, detecting a blue fluorescence emitted from the quartz glass crucible irradiated with the ultraviolet rays, and evaluating a state of oxygen deficiency defects in the outer layer of the quartz glass crucible on the basis of existence or non-existence of the blue fluorescence. The method allows hydrogen doping and water vapor introduction to attain nondestructive and easy evaluation on the state of the oxygen deficiency defects generated in the quartz glass crucible.

  • Publication number: 20240029479
    Abstract: In a case where input of data of a part of a plurality of items needed for a diagnosis is received, an item of which data is to be input next is changed based on the received data, so that an item that can efficiently reduce the candidates for the cause of the abnormal sound can be used as the item of which the data is to be input next, according to the received data. As a result, the candidates for the cause of the abnormal sound are efficiently narrowed down, and the number of man-hours needed to specify the cause of the abnormal sound can be reduced.

  • Patent number: 10355100
    Abstract: A first field effect transistor and a second field effect transistor are formed on a substrate. A silicon nitride liner is formed over the first field effect transistor and the second field effect transistor. An upper portion of the silicon nitride liner is converted into a thermal silicon oxide liner. A lower portion of the silicon nitride liner remains as a silicon nitride material portion. A first portion of the thermal silicon oxide liner is removed from above the second field effect transistor, and a second portion of the thermal silicon oxide liner remains above the first field effect transistor. Selective presence of the silicon oxide liner provides differential stress within the channels of the first and second field effect transistors, which can be employed to optimize performance of different types of field effect transistors.
