A semiconductor testing jig fixes a measurement target while it is held between a chuck stage and the measurement target. The semiconductor testing jig includes a base on which the measurement target is to be installed and which can be attached to the chuck stage. The base includes: a first main surface to become an installation surface for the measurement target; a second main surface opposite the first main surface and which is to contact the chuck stage; and a porous region containing a porous member. The porous region is provided selectively as seen in plan view, and penetrates through the base from the first main surface toward the second main surface.

It is an object of the present invention to provide a probe card capable of controlling generation of a scratch or an indentation in a connection pad and capable of controlling generation of heat in a connection pad and its vicinity having contacted a contact probe at low cost and in a simple way. A probe card includes a probe substrate, at least one contact probe electrically connected to a signal line provided to an insulating base of the probe substrate and fixed to the insulating base, and at least one engagement member installed on the contact probe at a position near a tip end portion of the contact probe. The engagement member has at least one engagement portion that makes abutting contact with another predetermined member during operation to restrain the operation of the contact probe.

A method of attaching a wafer by suction, includes a step of mounting a wafer on a right arm and a left arm of a transfer jig, moving the transfer jig toward a wafer suction stage in such a manner that a facing right arm surface of the right arm slides along and in contact with a first side surface of the wafer suction stage and a facing left arm surface of the left arm slides along and in contact with a second side surface of the wafer suction stage until the wafer comes to lie directly above a mounting surface of the wafer suction stage, mounting the wafer on the mounting surface by moving the transfer jig downward toward the wafer suction stage while maintaining the contacts, and attaching the wafer to the mounting surface by suction.

The present invention relates to a fusion polypeptide which comprises a polypeptide having G-CSF activity and a polypeptide having TPO activity and DNA which codes for the fusion polypeptide, to a fusion polypeptide in which a polypeptide having G-CSF activity and a polypeptide having TPO activity are fused via a spacer peptide and DNA which codes for the fusion polypeptide and to a polypeptide in which the fusion polypeptide comprising a polypeptide having G-CSF activity and a polypeptide having TPO activity is chemically modified with a polyalkylene glycol derivative. It also relates to an anemia-treating composition containing the fusion polypeptide as an active ingredient.
