An image pickup device is disclosed that has little deformation caused by thermal expansion of a transparent resin for sealing an image pickup element. The image pickup device includes an image pickup element having a light receiving surface, a micro-lens for condensing incident light to the image pickup element, a first transparent plate disposed on the light receiving surface of the image pickup element with the micro-lens in between, a transparent resin that seals the image pickup element and the first transparent plate, and a second transparent plate disposed on the transparent resin to face the first transparent plate.

Image pickup device and production method thereof

A process for producing a semiconductor device, includes: first melting by heating only a superior portion of a bump formed on an electrode on one principle surface of a semiconductor substrate; and second melting the entire bump by also heating an inferior portion of the bump.

Process for producing semiconductor device and apparatus therefor

A semiconductor device is provided that forms a three-dimensional semiconductor device having semiconductor devices stacked on one another. In this semiconductor device, a hole is formed in a silicon semiconductor substrate that has an integrated circuit unit and an electrode pad formed on a principal surface on the outer side. The hole is formed by etching, with the electrode pad serving as an etching stopper layer. An embedded electrode is formed in the hole. This embedded electrode serves to electrically lead the electrode pad to the principal surface on the bottom side of the silicon semiconductor substrate.

Semiconductor device suitable for a stacked structure

A method of resin sealing an electronic part, includes the steps of: providing a board where one or more of the electronic parts are mounted in an upper mold; melting a resin material received in a cavity forming part of a lower mold; and dipping the electronic part held by the upper mold into the molten resin so that the resin sealing is achieved. The resin material is received in the cavity forming part of the lower mold after the resin material is pressurized and dispersed in a sealing resin supply apparatus.

Method of resin sealing electronic part

A forming method of an electrode includes the steps of providing an electrode material on a conductive part; exposing the electrode material at a temperature equal to or higher than a melting point of the electrode material in an oxidizing atmosphere; and exposing the melted electrode material, in a reducing atmosphere, at a temperature equal to or higher than the melting point of the electrode material and lower than the temperature at which the electrode material is exposed in the oxidizing atmosphere.

Forming method of electrode and manufacturing method of semiconductor device

An image capturing device is disclosed that includes a light receiving element having a light receiving surface, a plate-like transparent member provided on the light receiving surface of the light receiving element, and resin provided to at least the periphery of the plate-like transparent member. The plate-like transparent member includes a first principal plane positioned on the light receiving element side and a second principal plane opposite the first principal plane. The first principal plane is greater in area than the second principal plane.
