3 AccuStable Our AccuStable Quality Label Our TailorSense Product Configurator For the most demanding applications, SMI has developed the AccuStable TM brand of sensors. For bare die and uncompensated packaged products, this means that the parts are guaranteed to have span and offset shifts of less than 1% over the life span of the product, based on 1000 hours of high temperature operating life (HTOL) testing. Our compensated systems meet this same definition, but additionally are guaranteed to have < 1% total accuracy error, which combines linearity, hysteresis and stability, and also show < 1% total output shift over the lifetime of the product. Only products combining an extraordinary accuracy with a long-time stability are allowed to have this high quality label. Several of SMI s new pressure sensor families qualify for this designation. The SM95 and SM30 die sensors have been qualified to 85 C and 150 C, respectively. These are available both as bare die and also packaged in SOIC16 package (the SM95 sensor) and in a new SOIC8 gauge package (the SM30 sensor). The newly-released harsh environment SM98 sensor has also earned the Accustable TM label, and has an operating temperature to 150 C. With the help of SMI s TailorSense Product Configurator the customer can build the perfect sensor system meeting all target requirements. The Product Configurator lets the customer define a sensor system tailored to the needs of a specific application. Pressure range, pressure type and accuracy can be configured as well as package type and package porting. In addition different options for the output type, compensated temperature range and supply voltage are available. By choosing these parameters based on the application, the customer is able to optimize the sensor system for its specific target application. For example, the full resolution and output range of the sensor system are available if the pressure range has been optimized for the specific application. And the configurable sensor output type, including amplified analog and digital I 2 C or SPI, allow integration with a variety of interfaces. The goal is that the customer does not have to compromise when choosing a sensor system solution. Several of our new digital-output compensated sensor systems are AccuStable TM. This includes the SM1221 series (for pressures ranging from 15 PSI to 29.9 PSI), the SM4221 series (from 2.5 PSI to 14.9 PSI), the SM5221 series (from 0.8 PSI to 2.0 PSI) and the SM6221 series (from 2.5 PSI to 14.9 PSI). Quality SMI's quality system is certified under ISO 9001 since Furthermore SMI fulfills the high quality standards of the automotive industry, and is therefore certified under ISO/TS since To ensure only highest quality material is used along the entire production chain SMI's maintains a Supplier Management System. It is SMI's quality policy to continually improve customer satisfaction by superior quality and 100% on time delivery. Our Company 3

4 Product Overview Bare Die For OEM and custom solutions, SMI provides a broad selection of bare pressure sensor die. With offerings from ultra-low pressure to media resistant high pressure, SMI can provide high performance solutions for your application while meeting the robust and high quality demands of the Automotive, Medical, and Industrial markets. The pressure sensor die are available in gauge and absolute pressure configurations. For more robust applications, a backside absolute pressure die is available. Pressure ranges vary from 0.07 PSI (~5 mbar) to 750 PSI (~50 bar). Packaged Solutions SMI carries a full selection of standard packaged products for the Automotive, Medical and Industrial markets. Packages range from the very small SOIC-8 plastic housing to the more versatile SOIC-16 plastic package with various porting options for design flexibility. A robust ceramic Dual Inline Package (DIP) is also available with stainless steel porting options for more stringent applications. To complement the package offering, SMI provides solutions for pressure ranges from 0.07 PSI (~5 mbar) to 120 PSI (~8.3 bar) with either an analog output or a digital interface or both. Compensated and System Solutions Various levels of integration are available from temperature compensated to fully signal-conditioned offerings. For the latter combining the pressure sensor cell with a signal-conditioning ASIC in a single package simplifies the use of advanced silicon micro-machined pressure sensors.

Both outputs can be used in parallel. The analog output is radiometric with supply voltage. Supply voltage is 5 V. The SM565x series of pressure sensors are constructed by attaching a piezoresistive pressure cell to a ceramic susbtrate with thick film resistors. These resistors are then laser-trimmed during manufacturing to provide zero offset and span calibration as well as temperature compensation. Our Company 5

7 Services Evaluation Boards SMI also offers evaluation boards and kits to support the design-in of the SMI pressure sensors by making evaluation testing and prototyping easier. Please contact Sales for details. Turnkey Solutions Many applications require the use of a pressure sensor die instead of a packaged standard product. In those cases, significant engineering effort is spent on the selection and development of suitable processes for membrane formation, media protection, electrical contact, and handling of the sensor die. The Design for Manufacturability is crucial in applications where product quality and commercial success are critical factors. Custom Solutions Over the years SMI has acquired broad expertise in many of these areas ranging from special coatings used for media protection to advanced packaging methods for easier handling of ultra-small sensors.

8 About the Elmos Group Elmos is a developer and manufacturer of semiconductor-based system solutions. Elmos offers to their customers the product which is the right solution for their tasks. Whether it is a chip which is customized to their requirements (ASIC), a standard product which can be implemented quickly (ASSP), or a complete micro-system as symbiosis of sensor and evaluation electronics. The core competency of Elmos is the development, production, and sale of mixed-signal semiconductors. Mixed-signal semiconductors represent the intelligence in an electronic system. Among other things, Elmos components evaluate sensor data and convert this analogue information into digital values. Only then can the sensor data be analysed and recorded precisely. With regard to vehicles, this means that a mixed-signal chip makes sense wherever analysis and switching takes place. Thus an integrated sensor can, for example, detect and analyse the rotational speed, acceleration, inclination angle, pressure, or even light. Numerous application opportunities also exist in industrial and consumer goods applications, for example in motion detectors, gesture and movement recognition, smoke detectors, or products with electric motors.
