Advanced Camera Detection and Measurement System in the Czochralski Process
Gjølstad, Endre Arnesen (Master thesis, 2018)In this thesis the Czochralski process is introduced as well as the technological setup used in the process. The three problems this thesis aim to solve are presented: implementation of automatic cold ingot detection, ... -
Automated Inspection of Quartz Crucibles - For use in the Czochralski Process
Saue, Morten (Master thesis, 2015)As the energy consumption in the world continues to increase it becomes more important to find alternative sources of electric energy. Photovoltaics is a method which utilizes the sun to create electricity. The Czochralski ... -
Linear and Nonlinear State Estimation in the Czochralski Process
Rahmanpour, Parsa; Bones, John Atle; Hovd, Morten; Gravdahl, Jan Tommy (Journal article; Peer reviewed, 2013)The Czochralski process is the only method used commercially for production of monocrystalline silicon for semiconductor and solar cell applications. This paper explores the use of mathematical modeling as an aid in ... -
Liquinert quartz crucible - Removal of OH groups in silica crucibles to reduce wetting between the crucible and the silicon melt
Strømmen, Mathias (Master thesis, 2018)When producing monocrystalline silicon ingots for the solar cell industry quartz crucibles are most commonly used. A quartz crucible used in the Czochralski (CZ) process will be used to pull ingots for more than 100 hours. ... -
The Relationship between Hydroxyl Content and Viscosity of Fused Silica for the Czochralski Process
Cheung, Tsz Chung (Master thesis, 2019)Kvartsglass av høy kvalitet brukes i digler til produksjon av monokrystallinske silisium "ingots" i solcellein- dustrien. Monokrystallinske wafere blir laget i slike digler ved Czochralski(CZ)-prosessen. Digelen kan ikke ...
