First-Time-Right Support


FTR – one of the most challenging goals in IC design – comes with highly complex requirements. Very different items need to play together but exist independently, much like an orchestra with many individual musicians but no conductor. For a foundry, FTR covers aspects ranging from process development to design support to process characterization. X-FAB meets this challenge through the following methods.


Process Selection

X-FAB offers a large selection of highly reliable semiconductor processes ranging from 1.0μm to 0.18μm bulk silicon- and SOI-based CMOS. They enable the design and manufacture of high-quality semiconductors that can exist in harsh automotive environments.


X-FAB’s processes and PDKs enable mixed-signal first-time-right silicon by using simulation models that represent silicon behavior as accurately as possible. These models include all required elements from a design point of view – spice models with a 3-to 6-sigma range for process limits, Monte Carlo models, and dedicated high-voltage models to cover high-voltage transistor behaviors.


Electronic System Design (ESD) robustness is another key element for automotive semiconductor devices. X-FAB‘s strong engineering support for custom I/O development and its extended ESD support with HV IO library building blocks proven in silicon facilitate the development of ESD-robust I/O. This support is enabled by transmission line pulse (TLP) measurements for ESD structures that support I/O development for >8kV HBM (human body model).

Design Methodology

X-FAB’s PDKs, libraries and IPs are fully supporting mixed-signal design methodology and are optimized for automotive applications interfacing the real world. Our analog/mixed-signal reference kit for Cadence design tools and flows can be downloaded as a ready-to-use design package that gives you a jump-start allowing fast and easy adoption of the mixed-signal design flow.


PDKs close the gap between EDA software and the foundry process. X-FAB PDKs are more than just a set of files. They contain all the data designers need to work with digital, analog and mixed-signal design flows in combination with our foundry data. PDKs provide out-of-thebox support for the latest design flows. They enable automotive designers to start IC development in their preferred EDA environments without any additional settings.


X-FAB is developing multiple robust and reliable IP that is easy to design with and also suitable for high-temperature (+175°C) environments typically found in the automotive space. This IP includes digital standard cell libraries, analog libraries, IO libraries, and SRAM and ROM compilers. In addition, X-FAB’s high-density non-volatile memory (NVM) IP blocks such as eFlash, NVRAM, EEPROM and OTP, among others, are qualified for high temperature use. Failure redundant solutions also are available, including NVM ECC.


X-FAB manufactures silicon wafers for mixed-signal integrated circuits (ICs) that target automotive applications. Its marketing network and client base span the Americas, Europe and Asia, offering manufacturing capacity of approximately 864,000 200mm-equivalent wafers per year. The largest specialty fab group worldwide, X-FAB differs from typical foundry services because of its specialized expertise in advanced analog and mixed-signal process technologies for harsh environments in the automotive market segment.

Analog and mixed-signal technologies are not intended for digital applications with the smallest possible structure sizes. Instead, they target analog automotive applications that can be integrated with additional functions such as high voltage, non-volatile memory and sensors. X-FAB optimally manages the product development flow and supply chain for your semiconductor products by combining solid, specialized expertise in advanced analog and mixed-signal process technologies with excellent service, a high level of responsiveness and first-class technical support.



As a pure-play foundry specializing in mixed-signal applications, X-FAB offers a wide range of open platform process technologies that combine advanced modular CMOS and BiCMOS platforms with a broad spectrum of additional analog functions and modular options. It covers voltages up to 40V, 60V, 100V, 200V & 700V for CMOS and SOI solutions, and offers a combination of high-voltage and NVM options with the lowest mask count in industry for advanced analog/mixed-signal process nodes.


Non-Volatile Memories at X-FAB

In the past couple of years the demand for non-volatile memories (NVM) has been growing steadily, driven mainly by mobile consumer electronics – from smartphones and tablet PCs to digital cameras and GPS navigation devices. In addition, the NVM content in these devices continues to grow rapidly in proportion to the logic device content.

This demand has increased the need for NVM for trimming, data- and code-storage functions used in smart systems-on- chip (SoCs).

To help automotive design teams design advanced SoCs for emerging applications, X-FAB offers a wide range of embedded non-volatile memory IP including eFlash, EEPROM, NVRAM, OTP, NV latches and poly fuses that cover process nodes from 1.0μm to 0.13μm.

The following pages showcase the different non-volatile memory types at X-FAB, their application space and technical features.
