  • Publication number: 20110024911
    Abstract: An electrical characteristics test for a semiconductor integrated circuit using a Kelvin contact method can be conducted in a pre-process without obstructing the reduction in size of a semiconductor chip or without complicating the circuit design. A probe card in a testing apparatus includes probes for Kelvin contact, the probes for Kelvin contact including a coil probe and a POGO pin probe disposed inside the coil probe, and a probe for two-terminal measurement. Electrode pads formed in each chip area over a wafer are in a relation of A=B<2A, given that the area of one of the electrode pads with which the probe for Kelvin contact comes into contact is B and the area of the other electrode pad with which the probe for two-terminal measurement comes into contact is A.

  • Publication number: 20100184162
    Abstract: A method is provided for producing an L-amino acid by culturing a microorganism belonging to the Enterobacteriaceae family and having the ability to produce an L-amino acid, in a medium to produce and accumulate the L-amino acid in the medium. The microorganism has been modified by introduction of a DNA fragment which includes a pho regulon promoter and a structural gene encoding an L-amino acid biosynthetic enzyme, which is ligated downstream of the promoter so that the gene is expressed by the promoter, and so that the activity of the L-amino acid biosynthetic enzyme is increased by the expression of the gene by the promoter. In this way, the L-amino acid that is produced in the medium can be collected. Furthermore, the phosphorus concentration in the medium is such that the expression of the gene by the promoter is induced.
