  1. 1. Development of an off-line silicon wafer warpage measuring tool

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Linas Čapas; [2020]
    Keywords : Photolithography; Semiconductor; Silicon; Wafer; Warpage; Mikrolitografi; Halvledare; Kisel; Kiselplatta; Vrängning;

    Abstract : Warped wafers and all the issues arise with them. are known issue in semiconductor industry. To solve those issues, the shape of the wafer needs to be known precisely. Current way of working when it comes to warped wafers is far from ideal within the company. READ MORE

  3. 2. In Situ Fabrication of Nanoporous Alumina into a Microwell Array

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Puja Romulus; [2018]
    Keywords : ;

    Abstract : Existing method for the antibiotic susceptibility test (AST) requires 2-3 days to produce the result. For patients with urinary tract infection (UTI), this lengthy process is critical because they must bear the pain during this period. READ MORE

  4. 3. Microfluidic Chip development for acoustophoresis assisted selective cell sorting

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : mohd adnan faqui shahzad; [2017]
    Keywords : ;

    Abstract : Analysis of blood samples is one of the major steps in diagnosing pathological conditions like cancer. The upstream sample preparation for the pathological cell analysis from complex biological fluid like blood, involves selective cell sorting. It can be achieved using fluorescently activated or magnetically activated cell sorters. READ MORE

  5. 4. Rear side BSF/emitter patterning of SHJ-IBC solar cells using selective deposition and hydrogen plasma etching of a-Si:H

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Mahmudul Hasan; [2016]
    Keywords : ;

    Abstract : Silicon heterojunction interdigitated back-contact (SHJ-IBC) solar cells have attracted considerable attention because of their potential to achieve very highly efficiency. However, the back contacting scheme leads to additional fabrication complexity mainly resulting from the formation of interdigitated n- (back surface field (BSF)) and p-type (emitter) hydrogenated amorphous silicon (aSi:H) strips.

  6. 5. Patterning of Highly Conductive Conjugated Polymers for Actuator Fabrication

    University essay from Linköpings universitet/Biosensorer och bioelektronik

    Author : Daniel Falk; [2015]
    Keywords : Biosensors; Bioelectronics; Microactuators; Conjugated polymers; Polypyrrole; PEDOT; Soft Lithography; Microcontact printing; Vapor phase polymerization; Drop-on-Demand printing; Photolithography; Lift-off;

    Abstract : Trilayer polypyrrole microactuators that can operate in air have previously been developed. They consist of two outer layers ofthe electroactive polymer polypyrrole (PPy) and one inner layer of a porous poly(vinylidene flouride) (PVDF) membranecontaining a liquid electrolyte. READ MORE
