Abstract: The present invention is a resist material containing: (i) a metal compound shown by the following general formula (M-1) and (ii) an organic solvent. An object of the present invention is to provide a metal-containing resist material having high sensitivity and high resolution particularly in EUV and electron beam lithography; and a patterning process using this material.

Abstract: An optical connector ferrule, an optical connector, and a composite fiber connecting assembly are provided. The optical connector ferrule includes a stationary ferrule having a first through-hole, a composite fiber, and a connecting ferrule having a second through-hole. The composite fiber includes a first optical fiber and a signal wire, and is placed in the first through-hole in the stationary ferrule. The connecting ferrule includes a conductive path. The stationary ferrule has a second end face abutting a third end face of the connecting ferrule. The first optical fiber has an end connected to an end of the second through-hole. The signal wire and the conductive path are connected to each other.

Abstract: An inspection device includes a sensor and processing circuitry. The sensor acquires an image formed on a first conveyance medium. The processing circuitry determines whether the image on the first conveyance medium is defective, based on the image acquired by the sensor. The processing circuitry controls to eject a second conveyance medium in a case where the image on the first conveyance medium is defective. The processing circuitry controls to display an image formed on the second conveyance medium in association with information indicating the first conveyance medium determined to be defective.
