摘要:
Sensor packages and methods for making a sensor device package for side mounting on a circuit board. A sensor device(s) in a mechanical layer (25) of silicon is sandwiched between first and second layers (24, 26) of glass to create a wafer. A first via(s) (30) is created in the first or second layers to expose a predefined area of the mechanical layer of silicon. A second via(s) (102) is created in the first or second layers. The least one second via has a depth dimension that is less than a depth dimension of the first via. A metallic trace (70, 72) is applied between the exposed area on the mechanical layer and a portion of the second via. The wafer is sliced such that the second via is separated into two sections, thereby creating a sensor die. The sensor die is then electrically and mechanically bonded to a circuit board at the sliced second via.

The present invention provides a method for manufacturing a bonded substrate by bonding a base substrate to a bond substrate through an insulator film, including at least: a porous layer forming step of partially forming a porous layer or forming a porous layer whose thickness partially varies on a bonding surface of the base substrate; an insulator film forming step of changing the porous layer into the insulator film, and thereby forming the insulator film whose thickness partially varies on the bonding surface of the base substrate; a bonding step of bonding the base substrate to the bond substrate through the insulator film; and a film thickness reducing step of reducing a film thickness of the bonded bond substrate to form a thin-film layer. As a result, there is provided the method for manufacturing a bonded substrate that enables obtaining an insulator film whose thickness partially varies with use of a simple method.

An interposer comprises a substrate and a plurality of posts. Each of the posts extends substantially through a thickness of the substrate. A method for forming an interposer comprises forming a fill hole in a first side of a substrate and a cavity in a second side of the substrate. The cavity is in fluidic communication with the fill hole. A plurality of posts is formed in the cavity. An encapsulant is injected through the fill hole into the cavity to encapsulate the plurality of posts.
