Abstract: A magnetic linear position detector includes a stator and a mover that is movable along a first direction with respect to the stator. One of the stator and the mover is provided with a magnetic detector. The other of the stator and the mover is provided with a magnet having a first face facing the magnetic detector. The first face is magnetized in such a manner that a magnetization direction changes in an arc shape around a magnetization center point. The magnetic detector is an element whose output changes depending on a direction of a magnetic field.

Abstract: When a plating layer is formed on through holes in semiconductor packages, first and second stacked bodies are stacked with first and second cavities formed in the first and second stacked bodies facing the inner side and are bonded together by applying adhesive to peripheral regions so that the cavities of the first and second stacked bodies form sealed spaces, and the through holes are formed such that part of the first and second stacked bodies including the bonding surface remains. Then, the through holes are plated to form the plating layer, the peripheral regions are removed as cutting allowances, i.e., removal regions, and the first and second stacked bodies are divided into a plurality of pieces along dicing lines to form semiconductor packages.
