XDH10 is X-Fab´s dielectric trench insulated smart power technology. Main target applications are analog switch ICs, driver ICs for capacitive, inductive and resistive loads and EL / piezo driver ICs for applications using 220V net supply. The typical breakdown voltage of the HV DMOS devices is >350V or >650V. The modular process combines DMOS, bipolar and CMOS processing steps that are compatible with dielectric insulation to provide a wide variety of MOS and bipolar devices with different voltage levels within a dielectric bi-directional high voltage trench insulation on the same die.

What happens when optical signals are converted to electrical signals? Focusing on the optical to electrical conversion process, this webinar sheds some light on the basics of light interaction from reflection, transmission, polarization and refraction to absorption with semiconductors devices. It explores electrical fields, recombination and lifetime, doping profiles, band structures and pn-junctions to determine what happens when light has been converted into electron-hole pairs. This webinar provides a solid overview of passive and active optical sensor elements manufactured in a mixed-signal CMOS process or added during post processing

The filters are constituted by a Fabry-Perot resonator formed by two Bragg mirrors separated by a patterned cavity. The filter response can be tuned by changing the geometric parameters of the patterning, and consequently the cavity effective refractive index. In this way, many different filters can be produced at once on a single chip, allowing multichanneling. The filter has been designed, produced, and characterized. The results for a chip with 24 filters are presented.

In this paper a modified MEMS foundry process allowing the production of 3D inertial sensors, such as accelerometers, gyroscopes and combinations, is introduced. The new MEMS process is suitable for a wide range of applications that use 3D accelerometers or gyroscopes. One-axis and three-axis designs can be produced with the same process, and the fabrication of complex inertial measurement units, in particular, the assembly process, is simplified.

We present a method for producing monolithically integrated CMOS optical filters with different and customerspecific responses. The filters are constituted by a Fabry-Perot resonator formed by two Bragg mirrors separated by a patterned cavity. The filter response can be tuned by changing the geometric parameters of the patterning, and consequently the cavity effective refractive index. In this way, many different filters can be produced at once on a single chip, allowing multichanneling. The filter has been designed, produced, and characterized. The results for a chip with 24 filters are presented.

Sensors are everywhere, serving as an interface between our analog world and the digital world of data processing in electronic systems. Is your design challenge – making sensor output signals available to complex digital systems – further complicated by the need for low noise, temperature-dependent behavior and non-linear effects? If you are looking for solutions for low noise amplification and temperature drift, non-linearity or signal offset compensation, don’t miss this free webinar. It helps designers select the right technology for low-noise and high-precision sensor interfaces. You’ll get tips for achieving excellent matching for robust circuits, and see how X-FAB’s sophisticated modelling enables first-time-right analog and mixed-signal designs.

X-FAB, a pure play foundry, has already extensive experience in volume production of monolithic integrated MEMS devices. The idea of combining CMOS and MEMS processes to obtain monolithic integrated sensor solutions is a logical, consequent step following the “More than Moore” strategy.

PIN photodiodes are often used in optical integrated circuits. Although they can feature a very good RF-performance, this can be effected by the optical power density of the incident light. The influence of this effect on the RF-performance of PIN photodiodes is described. When a critical optical power density in the epi-layer is exceeded the 3dB frequencies are cut off. An analytical equation is derived to describe the effect. The results are compared to RF measurements and verified by numerical simulation.

Moore’s law has been a strong influence on mainstream microelectronics over the past few decades, where the trends of decreasing feature size and increasing transistor count have driven the semiconductor industry forward. This philosophy has worked very well for memories and microprocessors in the digital world. Additional analog functions, by interfacing with the physical world, enable cost-optimized and value-added system solutions.
