In this paper, micromachined acceleration sensors as ready-to-use Intellectual-Property-Blocks (IP-Blocks) are introduced. These standard elements are available for a special surface micromachining foundry technology. They are ready to use, characterized and qualified design elements, which can be customized by changing the peripheral elements such as bond pads, and allow the fast prototyping and production start of high-performance inertial sensors.

Visualization is still the most important tool in medical diagnostics to allow for the physician, in combination with their medical knowledge, to detect diseases within the human body and choose healing treatments in order to enable recovery. For minimal invasive surgical operations that use endoscopic tools, imaging camera modules that have both a small volume and a good resolution are necessary to ensure the success of the surgical treatment.
Microsystem technologies now allow for the direct integration of imaging optics and sensors in a system.

Miniaturized video endoscopes with an imager located at the distal end and a simplified opto-mechanical layout are presented. They are based on a CMOS imager with 650 x 650 pixels of 2.8 μm pitch and provide straight view with 75° and 110° field of view at f/4.3. They have an outer diameter of 3 mm including the shell and a length of approx. 8 mm. The optics consist of polymer lenses in combination with a GRIN and a dispensed lens. Using a simple flip chip assembly, optical axis alignment better than 10 μm and a contrast of 30 % at 90 LP/mm was achieved. The 75° FOV system was sealed at the front window using a solderjetting technology, providing 10-9 mbar*l/s leakage rates even after several autoclave cycles.

This free webinar introduces X-FAB’s Hall effect sensor device that detects and measures magnetic fields directly on the chip, making magnetic field-sensing design much faster. You’ll learn how the Hall sensor element – available as a completely characterized building block in X-FAB’s 0.18 micrometer modular high-voltage technology, XH018 – can be combined with other features of the XH018 process to enable a broad range of applications. For example, contactless detection or measurement of magnetic fields, and applications in which a magnetic field is used for indirect measurement of distance, position, rotational angle, speed or an electric current.

In the past five years we have seen a huge step in the evolution of MEMS applications. Some may even call it a revolution. Traditionally, Inkjet printer heads and automotive applications have dominated MEMS volume production. Today, demand for MEMS is particularly high in the consumer and mobile sector with further applications appearing every day. Part of this MEMS revolution has been the changing requirements for associated ASIC CMOS intelligence. Many manufacturers who currently use discrete MEMS devices are now seeing the benefits of integrated CMOS.

Sub-wavelength structures in metal films have interesting optical properties that can be implemented for sensing applications: gratings act as wire grid polarizer, hole arrays with enhanced transmission can be used as spectral filters. This paper demonstrates the feasibility of these nanostructures using 180 nm and 90 nm complementary metal-oxide semiconductor (CMOS) processes. The metal layers of the process can be used for optical nanostructures with feature sizes down to 100 nm.

An infrared focal plane array with 16 x 8 pixels is presented. The not-cooled thermopile sensor array has been completely fabricated in CMOS technology. The main field of application of this sensor is to detect the presence of persons in buildings by their own thermal radiation. For a wide spread use of this sensor a low cost production with established CMOS technologies is necessary. The chip embraces the sensor pixels and highly integrated electronic circuits to allow a simple sensor interfacing.
