We propose and implement an adhesion test configuration called “modified single cantilever adhesion test” (M-SCAT) that can be employed to determine the adhesion strength of epoxy molding compound (EMC) and photo solder resist (PSR) interface in

2015 IEEE International Electron Devices Meeting (IEDM).
For the first time, 20nm DRAM has been developed and fabricated successfully without extreme ultraviolet (EUV) lithography using the honeycomb structure (HCS) and the air-spacer technology. The cell capacitance (Cs) can be increased by 21% at the sam

An advanced bottom electrode contact (BEC) was successfully developed for reliable high-density 256 Mb phase-change random access memory (PRAM) using a ring-type contact scheme. This advanced ring-type BEC was prepared by depositing very thin TiN fil

The photoluminescence linewidths and excition lifetimes of free excitons in GaAs/AlGaAs multiple quantum wells were systematically investigated as a function of temperature, quantum well width, and carrier density. The experimental results showed tha
