摘要: A method of fabricating a trench capacitor, and a trench capacitor fabricated thereby, are disclosed. The method involves the use of a vacuum impregnation process for a sol-gel film, to facilitate effective deposition of high-permittivity materials within a trench in a semiconductor substrate, to provide a trench capacitor having a high capacitance whilst being efficient in utilisation of semiconductor real estate.
