Much has been written about fume fever (brass caster's ague, zinc chills, zinc shakes), and lead poisoning in brass foundries has been dealt with recently by Stalker (1947) and Hamlin and Weber (1947), but the references to pulmonary fibrosis amongst non-ferrous foundry workers are few. Stalker wrote that " the incidence of advanced silicosis has been generally low among [brass] foundrymen ". M...

1996 ii The thesis of Brett Alan Warneke is approved. Figure 3-7 Cross-sectional diagram of an aluminum trace running between oxide plates and contacting a polysilicon piezoresistor. The oxide and first metal overetch into the silicon substrate causes the trace Figure 3-8 SEM of a Skeleton Crew accelerometer with bond wires providing 9.6 µgm of additional proof mass.

OBJECTIVES The overall objective was to assess the role of aluminum dust and fumes in the aluminum foundry (Al-F) in generating local inflammation in the respiratory tract, which may lead to induction and elicitation of occupational asthma and fibrosis. To understand the underlying mechanisms of involving particles from foundry, a long-term study was performed on rats. MATERIALS AND METHODS P...

A new CMOS active pixel image sensor is reported. The sensor uses a 2.0 p n double-poly, double-metal foundry CMOS process and is realized as a 128 x 128 array of 40 p n x 40 pm pixels. The sensor features TTL compatible voltages, low noise and large dynamic range, and will be useful in machine vision and smart sensor applications.

Photonic integration within state-of-the-art CMOS and DRAM processes leverages the existing electronic manufacturing infrastructure to minimize cost. Suitable design techniques combined with in-foundry optimization or post-processing have enabled integration within several advanced technologies. !2012 Optical Society of America OCIS codes: (250.5300) Photonic integrated circuits; (200.4650) Opt...
