A semiconductor device utilizing redistribution layers to couple stacked die is disclosed and may include a first semiconductor die with a first surface comprising bond pads, a second surface opposite the first surface, and sloped side surfaces between the first and second surfaces, such that a cross-section of the first die is trapezoidal in shape. A second semiconductor die with a first surface may be bonded to the second surface of the first die, wherein the first surface of the second die may comprise bond pads. A passivation layer may be formed on the first surface and sloped side surfaces of the first die and the first surface of the second die. A redistribution layer may be formed on the passivation layer, electrically coupling bond pads on the first and second die. A conductive pillar may extend from a bond pad on the second die to the second redistribution layer.

Disclosed are an image sensor package and a method for manufacturing the same. A sealing portion is formed between an image sensor die and a glass substrate to completely isolate the sensing portion of the image sensor die from external environment. Electrically conductive bumps are formed outside of the sealing portion to electrically connect the image sensor die to the glass substrate. The image sensor die can be sealed by a cap while the image sensor die is connected to the glass substrate via the electrically conductive bumps.

Semiconductor packages are disclosed. An exemplary package includes horizontal leads each having a first side and an opposite second side. The second side includes a recessed horizontal surface. Two stacked semiconductor chips are within the package and are electrically interconnected in a flip chip style. One chip extends over the first side of the leads and is electrically connected thereto. The chips are encapsulated in a package body formed of an encapsulating material. The recessed horizontal surface of the leads is covered by the encapsulating material, and a portion of the second side of each lead is exposed at an exterior surface of the package body as an input/output terminal. A surface of one or both chips may be exposed. The stack of chips may be supported on the first side of the leads or on a chip mounting plate.

An improved process for bonding a semiconductor chip to a substrate is disclosed. In the process, a gold bump is formed on an aluminum bond pad of the chip thus forming a flip chip. A screen with an opening is placed on the substrate prior to dotting insulating epoxy on the opening. The epoxy is bladed with a printing blade thus forming an epoxy layer having a predetermined area and uniform thickness. The flip chip is, thereafter, placed on the substrate such that the gold bump is brought into electrical contact with a lead finger of the substrate through thermocompression bonding. Then the chip and substrate are put in an oven in order to permanently cure the epoxy layer. It is preferable to precure the epoxy layer prior to the permanent curing step thereby allowing thermal stress to be distributed to both the gold bump and the precured epoxy layer.
