XDM10 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 110V net supply. The typical breakdown voltage of the HV-DMOS devices is >350 V or >275V. 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.

The huge demand for high voltage, high current power devices on Silicon on Chip (SoC) has led to the development of Lateral IGBT (LIGBT), touted as the best candidate to serve these two purposes. This paper is the first to review the research works on LIGBTs published till now. The LIGBTs are categorized into four types based on different technologies applied, mainly Junction Isolation (JI), Silicon On Insulator (SOI), Partial SOI (PSOI) and Membrane, and ten varieties based on their device mechanisms, such as Reverse Conducting, Trench Gate and Super Junction.

In a typical ASIC semiconductor facility, there are hundreds of products processed on dozens of different equipments with unequal characteristics. Sequence depended equipment setups, failures, preventive maintenance and product specific re-entrant flows cause a high variability in factory performance measures. Also different customer demands, which are natural in the foundry business, should be taken into account (e.g. delivery dates or throughput). To reduce the variability and to improve the factory performance a robust and efficient dispatching and scheduling strategy is vital.

Inline defect control systems are used across the semiconductor industry for detection of process failures like equipment issues or yield problems. Besides to the goal to improve the yield of each process, it may have a negative influence on factory performance as well. The measurement of all lots in all defect control monitors of a process is not feasible, even when there are bottleneck situations.

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.
