Second batch of 10 Silicon sensor wafers for the Atlas pixel detector


Here is a list of the wafers, with foundry numbering (this number is physically written on the n-side, near to the major flat).
  • S1-16S -- Single metal ---Tested -- Sent to Bonn 2nd/3/98
  • S1-17S -- Single metal ---Tested -- Sent to Bonn 2nd/3/98
  • S1-18S -- Single metal ---Tested -- Sent to CPPM 3rd/2/98
  • S1-19S -- Single metal ---Tested -- Sent to LBL 2nd/3/98
  • S1-20S -- Single metal ---Tested
  • S1-21S -- Single metal ---Tested -- Sent to LBL 2nd/3/98
  • S1-13D -- Double metal -- Tested
  • S1-22D -- Double metal -- Tested
  • S1-23D -- Double metal -- Tested -- Sent to CPPM 3rd/2/98
  • S1-24D -- Double metal -- Tested -- Sent to Bonn 2nd/3/98

    The standard chip labeling scheme is assumed in the plot legends. The wafer ID are now the standard ones. For a reference, please reach the Atlas web page in Dortmund.

    These wafers have no minor flat. According to the SEMI standard they look like {111} p-type material.
    According to the measurements made in Munich the wafers are made of n-type, {100}-oriented material.


    The logbook which is automatically produced by the LabView program is also available.




    RESULTS


    The I-V characteristics are available as jpg pictures. The quality is limited by the available disk space on the server. We shall improve it.


    Here is an overview of I-V curves measured at 23 +/- 1 C for
