R

oche (SIX: RO, ROG; OTCQX: RHHBY) and IBM (NYSE: IBM) announced an agreement to

develop a nanoporebased sequencer that will directly read and decode human DNA quickly and efficiently. Focused on advancing IBM‘s recently published “DNA Transistor” technology, the colla- boration will take advantage of IBM‘s leadership in microelectronics, information technology and com- putational biology and Roche‘s expertise in medical diagnostics and genome sequencing. http://www.454.com

asertec Corporation of Japan has joined SEMATECH’s 3D Interconnect Program at the

College of Nanoscale Science and Engineering (CNSE) of the University at Albany, and will partner with SEMATECH to develop robust, cost-effective process metrology technology solutions for ready- ing high-volume via-mid through-silicon via (TSV) manufacturing. The collaboration between Lasertec and researchers from SEMATECH’s 3D interconnect program will include investigations and comparisons of 3D TSV depth metrology schemes. This work is necessary not only for TSV RIE process control, but also for providing critical feed forward data for wafer thinning and TSV expose processes.

To facilitate this work, Lasertec will place a 300mm TSV infrared (IR) etch metrology tool in SEMATECH’s 3D R&D Center, providing advanced measurement capabilities that will enable accurate, repeatable TSV

depth measurements over a range of TSV dimensi- ons.

S

ensoTech, Germany, presented its LiquiSonic®

sensors. Thanks

to the innovative tantalum coating, the sensors of LiquiSonic®

product

range even withstand aggressive process liquids, for example sulfuric acid, hydrofluoric acid or hydrochloric acid at over 130°C (266° F). As a well-priced alternative compared to sensors completely made of tantalum, the user can rely on the stability of coating and on the accuracy of temperature and concentration measurement. The possible coating thickness is ranging from 10µm to 100µm, whereas for corrosive applications a thick- ness of approx. 30µm up to 50µm is recommended. In comparison to plastic coatings such as PFA or Halar using temperatures below 130°C, the tantalum sensor provides the perfect solution in harsh process conditions. The tantalum coating even shows advan- tages compared to the gold coating.

Thus, higher coating thicknesses are possible for tantalum sensors. The sensor reacts less sensitive to mechanical stress and is characterized by higher chemical resistance, for example to matter containing chlorine.
