  • Method for producing a doped region in a substrate
    Patent number: 5273934
    Abstract: A doped region (14) is produced in a substrate (11) of silicon by diffusion of dopant from a doped glass layer (13) that is arranged on an intermediate layer (12) situated on the substrate (11) . The dopant concentration in the doped region (14) is thereby limited by the intermediate layer (12). The doped glass layer (13) is particularly produced by chemical vapor deposition of (B(OSi(CH.sub.3).sub.3).sub.3).

    Assignee: Siemens Aktiengesellschaft
    Inventors: Karl Ehinger, Michael Bianco, Helmut Klose
  • Temperature probe
    Patent number: 5131759
    Abstract: A temperature probe (20) is provided which comprises a sensor (22) mounted within a protecting tube (38). A gap is defined between the sensor (22) and the protecting tube (38). The gap (46) between the sensor and the protecting tube is filled with a dry gas such a helium.
