Abstract:
In one embodiment, a shielded electronic module is formed on a substrate. The substrate has a component area and one or more electronic components attached to the component area. One set of conductive pads may be attached to the component area and another set of conductive pads may be provided on the electronic component. The conductive pads on the component area are electrically coupled to the conductive pads of the electronic component by a conductive layer. A first insulating layer is provided over the component area and underneath the conductive layer that may insulate the electronic component and the substrate from the conductive layer. A second insulating layer is provided over the first insulating layer that covers at least the conductive layer. In this manner, the conductive layer is isolated from an electromagnetic shield formed over the component area.
Abstract:
An electrode surface of a horizontal semiconductor chip and a substrate are joined together through a plurality of first joint portions including a plurality of joint portions at which a plurality of electrodes formed on the electrode surface are joined to the substrate. A no-electrode surface of the horizontal semiconductor chip and a heatsink are joined together through a second joint portion at which the no-electrode surface and the heatsink are joined together. In a plan view from a direction normal to a principal surface of the substrate, when a region inside the outline of the rough shape of an aggregate of the first joint portions is a first joint region and a region inside the outline of the second joint portion is a second joint region, the first joint region and the second joint region are the same in position, shape, and size.
Abstract:
A method of manufacturing a ceramic electronic component prevents variations in characteristics even when the ceramic electronic component is embedded in a wiring board. Ceramic green sheets containing an organic binder having a degree of polymerization in a range from about 1000 to about 1500 are prepared. A first conductive paste layer is formed on a surface of each of the ceramic green sheets. The ceramic green sheets are laminated to form a raw ceramic laminated body. A second conductive paste layer is formed on a surface of the raw ceramic laminated body. The raw ceramic laminated body formed with the second conductive paste layer is fired.
