Global Device Modeling Services

Introduction

Integrated Circuit (IC) design stands on the shoulders of device modeling and characterization. The semiconductor industry requires fast and accurate device models.

Circuits are being pushed to higher frequencies as device geometries are becoming smaller with higher chip device count.

Without adequate models, designers cannot accurately simulate their circuits. This leads to poor circuit performance on the lab bench.

Some large companies designate entire groups to device characterization and model extraction.

This requires measuring and deciphering mountains of data as semiconductor processes are fine-tuned. To overcome these challenges, combined expertise in the following areas are required.

• Low leakage DC measurements with pA accuracy
• Highly sensitive RF measurements to 100 GHz and beyond
• Wafer probing methodologies – RF, DC, probe card, etc.
• The latest advances in device models – BSIMCMG, HiSIM_HV, etc.
• Model extractions using IC-CAP or Model Builder Program
• Assure models will provide accurate results across multiple simulators
• Designing on-wafer test structures to expose process parameters
• Understanding and modeling the variation of device parameters within a process and across the wafer
• Model and predict device reliability
• Refining model libraries provided by foundries
• Comparing devices from different foundries using existing models
• Measurement automation software and data handling

Be First To Market

Time-to-market is critical, especially in fast-moving areas of the semiconductor industry like mobile phone platforms, IoT sensors, or automotive circuits.

Increasingly, companies are requiring customer delivery of first prototypes due to cost and closing market opportunities. This makes the modeling and characterization crucial.

Characterizing an unfamiliar model can take months to perfect and result in the loss of an entire market window. Accurate characterization and validation of device models provides the confidence to successfully deliver today’s products to market.

Typical device modeling and characterization labs require cohesive moving parts — getting any of these wrong could cost your team time and money.

• Skilled model extraction engineers
• Skilled test engineers
• Probing systems with appropriate probes for both RF and DC testing
• Test equipment with cables and accessories
• Software to drive measurements and analysis
• Software for model extraction and model quality analysis
