  1. 16. A microtechnology-based sensor system for deepwater analysis from a miniaturized submersible

    University essay from Ångström Space Technology Centre (ÅSTC)

    Author : Katarina Smedfors; [2010]
    Keywords : CTD; MEMS; microtechnology; sensors; thin film metallization; microelectrodes;

    Abstract : The aim of this master thesis has been to design, and partly manufacture and evaluate, a highly miniaturized, on-chip conductivity-temperature-depth (CTD) sensor system for deepwater analysis also including electrodes for pH and chloride ion concentration measurements. The microtechnology-based sensor system will be a vital instrument onboard the Deeper Access, Deeper Understanding submersible, which will be small enough for deployment through bore holes into the subglacial lakes of Antarctica.

  3. 17. Wet etching of optical thin films

    University essay from JTH, Kemiteknik

    Author : Curt Edström; [2010]
    Keywords : Thin film; Wet etching; Optical coating; Physical vapour deposition;

    Abstract : Evaluation of the wet etching properties of several different thin film oxidesgrown by physical vapour deposition was performed in this work. MgO, Al2O3,SiO2, TiO2, HfO2 ZrO2 and Y2O3 were coated on two types of substrates; Si andborosilicate glass and etching tests were performed in different etchingsolutions. READ MORE
