Investigations were performed to determine whether resist shrinkage during post-exposure bake can account for the observed discrepancies between real process window data for Negative Tone Development systems and the current physical model for these systems. Read More PDF >
Product Spotlight: VLSI's Solar Cell Certification Service
With 27 years of experience in supplying calibration standards for the semiconductor industry, VLSI Standards successfully entered the photovoltaic (PV) market approximately 3 years ago with solar reference cells for calibrating solar simulators and a solar reference cell certification service for manufacturers and users of solar simulators. VLSI's Solar Cell Certification Service extends this service to production solar cells and provides ISO accredited traceable measurements of short circuit current (Isc), open circuit voltage (Voc), maximum power (Pmax), cell area, spectral response (or QE), fill factor, conversion efficiency, and temperature dependence. This enables solar cell manufacturers to verify and confirm the targeted efficiency levels and other performance metrics for their production line processes which, in turn, guarantee these values to their end customers.
The photovoltaics industry has its own unique calibration standards needs, especially regarding measuring all-important solar-cell and module conversion efficiencies. By properly and consistently monitoring and calibrating the solar simulators used to determine those efficiencies, the quality and credibility of the measurements can be drastically improved, which has enhanced revenue and performance-reliability ramifications all the way up the PV system validation value chain.
VLSI Standards Solar Cell Certification Service is uniquely positioned with a turn-around time of only 4 weeks, excellent repeatability, and ISO 17025 accreditation with global traceability (through customer's choice among NREL, AIST, and PTB) for Asian, US, and European Markets.
