摘要:
A two-layered copper-clad laminate material, in which one surface or both surfaces of a polyimide film having a thickness of 12.5 to 50 μm is subjected to a modification treatment by means of a glow discharge plasma treatment in an oxygen gas atmosphere, and a copper layer having a thickness of 1 to 5 μm is formed by means of sputtering or electroplating on one surface or both surfaces of the polyimide film after the modification treatment; characterized in that the integrated intensity ratio of a C1S peak at 287 to 290 eV to a C1S peak at 283 to 287 eV, obtained by analyzing the photoelectron spectroscopy (XPS) spectra of the surface of the polyimide film after the plasma treatment, is within the range of 0.03 to 0.11. The present invention aims at discovering; as a consequence of performing surface characterization by subjecting the PI film surface to XPS analysis before and after the plasma treatment, and of evaluating the dissolution properties and adhesive strength of the PI film before and after the plasma treatment; a two-layered copper-clad laminate material that is ideal to be processed during a wet PI etching step, and a production method for said two-layered copper-clad laminate material.

A two-layered copper-clad laminate material in which a copper layer having a thickness of 1 to 5 μm is formed by means of sputtering or electroplating on one surface or both surfaces of a polyimide film having a thickness of 12.5 to 50 μm after a plasma treatment is performed in a nitrogen gas atmosphere, the two-layered copper-clad laminate material being characterized in that the dissolution of the aforementioned polyimide film with an etching liquid is delayed compared with a polyimide film that is not subjected to the plasma treatment, the aforementioned dissolution being delayed as a consequence of modifying the surface of the polyimide film by incorporating nitrogen into the polyimide film by means of the plasma treatment in the nitrogen gas atmosphere.

A radio network controller includes a block error detection unit configured to receive a data block from the base station and to detect a block error, and a target SIR calculation unit configured to calculate a target SIR based on the detected block error rate. The target calculation unit sets a first time section, which indicates a time section from a detection of the block error to the notification of the target SIR is to the base station when the block error is detected, shorter than a second time section, which indicates a time section from the detection of the block error to the notification of the target SIR to the base station when the block error is not detected.

A die pick-up apparatus and method using a wiper that has a tip end moving in and out of an adherence surface of a die stage and a shutter that is moved with the wiper while blocking a suction window formed in the adherence surface. When picking up a semiconductor die, the tip end of the wiper is aligned with a first end of the die, the wiper is moved along the adherence surface while the tip end of the wiper is protruded from the adherence surface with the die being suction-held by a collet. A suction opening is sequentially opened between a first end surface of the suction window and a seat surface of the wiper as the wiper is moved, and a dicing sheet attached to the die is suctioned into the suction opening that has been opened and sequentially peeled off from the die.

A die pick-up apparatus and method using a die stage having an adherence surface, a suction window formed in the adherence surface and larger than a semiconductor die to be picked up, and a cover plate that slides along the adherence surface and opens and closes the suction window. When picking up the semiconductor die, the surface of the cover plate is caused to be closely contacted to a dicing sheet that is attached to the die so that the die is within the boundary of the upper surface of the cover plate that closes the suction window, and then the dicing sheet is sequentially peeled off as, while the die is being suctioned by a collet, the cover plate gradually slides to sequentially open the suction window and allow the dicing sheet to be suctioned into the opened suction window.
