General lighting by use of LED-Chips is one of the strongly growing markets today and also in future. One of the trends goes to LEDs with higher and higher luminous fluxes per chip area to get the best price per lumen on the market. Unfortunately, such large LEDs produce a lot of heat, which must be spread to avoid overheating and shorter lifetime of the LEDs. Another approach is the use of many small...
The Stud Bump Bonding (SBB) flip chip technology on Molded Interconnect Devices (MID) is a highly promising solution to the increasing demand for reliable interconnection technology at high temperatures, a miniaturized assembly and a reduction of costs and parts.
During the last years, jetting processes for higher viscosity materials have gained widespread interest in microelectronics manufacturing. Main reasons for this interest are high throughput/productivity of jetting, contactless material deposition, high volume precision and freely designable deposition patterns. Especially the higher viscosity materials are of interest for the integration of a variety...
Radar sensors are already employed in production model vehicles e.g. for adaptive cruise control (ACC) systems. Further development of driver assistance systems has also led to the use of radar sensors in active safety systems (active brake assistance, collision warning, emergency braking, etc). However, the costs of manufacturing such radar-based systems, capable of gathering reliable information...
Recent years have shown the tremendous growth of electronic use in medical devices. Especially active implants and hearing aids have driven that trend to today's ultra-small devices embedded into the body. While the integrated circuits' features a ever-decreasing critical geometries and surging performance numbers, the delivery format of such advanced chips is seldom providing the engineering teams...
As the development of microelectronics is still driving towards further miniaturization, new materials, processes and technologies are crucial for the realization of future cost effective microsystems and components. Futures ICs and passives will also decrease in size, e.g. for RF-ID applications forecast die sizes are smaller than 250 ?m, thicknesses less than 50 ?m and pitches way below 100 ?m....
This paper describes the design, simulation and measurement of interconnects of buried active 77 GHz chips to a high frequency substrate using microvia technology. The embedding technology proposed offers great opportunities for a very broad range of frequencies and applications as well as a large potential for cost reduction.
