A semiconductor chip comprises a substrate, a die attach material, and a die. The substrate comprises an upper surface and a lower surface opposing the upper surface. The die attach material is on the upper surface of the substrate. The die comprises a bottom surface bonded to the upper surface of the substrate by the die attach material, a top surface opposing the bottom surface, and a side wall adjacent to the top surface and the bottom surface. A shortest distance across an exterior of the side wall from the bottom surface to the top surface defines an exterior surface distance. The die further comprises a die height measured from where the side wall meets the bottom surface to where the side wall meets the top surface. The exterior surface distance is longer than the die height.

Limiting failures caused by dendrite growth on semiconductor chips

A package includes a circuit that includes at least one active area and at least one secondary device area, a support configured to support the circuit, and a die attach material. The circuit being mounted on the support using the die attach material and the die attach material including at least one channel configured to allow gases generated during curing of the die attach material to be released from the die attach material.

A package includes an integrated circuit that includes at least one active area and at least one secondary device area, a support configured to support the integrated circuit, and a die attach material. The integrated circuit being mounted on the support using the die attach material and the die attach material including at least one channel configured to allow gases generated during curing of the die attach material to be released from the die attach material.

Integrated circuit having die attach materials with channels and process of implementing the same

A device comprises a base, a die, leads, and an electrically-insulating die housing covering the die. The base comprises a die mounting section in which the die is mounted. The leads extend away from the die mounting section and are electrically connected to the die. The base further comprises a base mounting section and a recessed section. The recessed section comprises a recess between the die mounting section and the base mounting section. The base further comprises a first side, a second side opposing the first side, and a thickness measured between the first and second sides. The thickness of the base throughout the recessed section is less than the thickness of the base throughout the base mounting section. The base further comprises an opening extending at least through the base mounting section from the first side to the second side.

Robust electronics mounting device

The base of an integrated circuit package comprises a first side, and a second side opposing the first side. The base further comprises, a base mounting section, a die mounting section, and a recessed section. The recessed section comprises a recess between the die mounting section and the base mounting section. The base further comprises an opening extending through the base from the first side to the second side. At least a portion of the recess intersects with the opening.
