1. 16. Chemical Mechanical Polishing of Silicon and Silicon Dioxide in Front End Processing

   Författare :Markus Forsberg; Jörgen Olsson; Jyrki Molarius; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics; chemical mechanical polishing; chemical mechanical planarization; silicon; silicon dioxide; front end; shallow trench isolation; deep trench isolation; bipolar transistor; BiCMOS; wafer bonding; Elektronik; Electronics; Elektronik;

   Sammanfattning : Chemical mechanical polishing (CMP) has been used for a long time in the manufacturing of prime silicon wafers for the IC industry. Lately, other substrates, such as silicon-on-insulator has become in use which requires a greater control of the silicon CMP process. LÄS MER

3. 17. Vertical High-Voltage Transistors on Thick Silicon-on-Insulator

   Författare :Ulrich Heinle; Gehan Amaratunga; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics; SOI; vertical DMOS; trench isolation; power electronics; integration; on-resistance; capacitive coupling; self-heating; switching; Elektronik; Electronics; Elektronik; Elektronik; Electronics;

   Sammanfattning : More and more electronic products, like battery chargers and power supplies, as well as applications in telecommunications and automotive electronics are based on System-on-Chip solutions, where signal processing and power devices are integrated on the same chip. The integration of different functional units offers many advantages in terms of reliability, reduced power consumption, weight and space reduction, leading to products with better performance at a hopefully lower price.

7. 20. Thermally stable electrical contacts to 6H silicon carbide

   Författare :Nils Lundberg; Mikael Östling; Claude Jaussaud; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; I-V current -voltage ; C-V capacitance-voltage ; rectifying; ohmic; interface; silicide; carbide; epilayer; Schottky barrier height; current rectification ratio CRR ; specific contact resistivity; transmission line model TLM ; contact resistance; transfer length; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : Silicon Carbide (SiC) are at present being developed for use in high temperature (≥ 500◦C) and high-power environments under which conventional semiconductors can hardly perform.  Thermally stable electrical contacts are essential to the ability of SiC to function under such extreme conditions.
