摘要:
A component, e.g., interposer has first and second opposite sides, conductive elements at the first side and terminals at the second side. The terminals can connect with another component, for example. A first element at the first side can comprise a first material having a thermal expansion coefficient less than 10 ppm/°C, and a second element at the second side can comprise a plurality of insulated structures separated from one another by at least one gap. Conductive structure extends through at least one insulated structure and is electrically coupled with the terminals and the conductive elements. The at least one gap can reduce mechanical stress in connections between the terminals and another component.

A through-substrate via (TSV) die (200) includes a plurality of TSVs (216) including an outer dielectric sleeve (221) and an inner metal core (220) and protruding TSV tips (217) including sidewalls that emerge from the TSV die. A passivation layer (231) lateral to the protruding TSV tips is on a portion of the sidewalls of the protruding TSV tips. The passivation layers is absent from a distal portion of the protruding TSV tips to provide an exposed portion of the inner metal core. The TSV tips include bulbous distal tip ends (217(a) including a first metal layer (241) including a first metal other than solder and a second metal layer (242) including a second metal other than solder that covers the exposed tip portion. The bulbous distal tip ends cover a portion of the TSV sidewalls and are over a topmost surface of the outer dielectric sleeve, and have a maximum cross-sectional area that is > 25 % more as compared to a cross-sectional area of the protruding TSV tips below the bulbous distal tip ends.

摘要:
A method for fabricating semiconductor components (90) includes the steps of: providing a semiconductor substrate (52) having a circuit side (54), a back side (56) and conductive vias (58); removing portions of the substrate (52) from the back side (56) to expose terminal portions (76) of the conductive vias (58); depositing a polymer layer (78) on the back side (56) encapsulating the terminal portions (76); and then planarizing the polymer layer (78) and ends of the terminal portions (76) to form self aligned conductors embedded in the polymer layer (78). Additional back side elements, such as terminal contacts (86) and back side redistribution conductors (88), can also be formed in electrical contact with the conductive vias (58). A semiconductor component (90) includes the semiconductor substrate (52), the conductive vias (58), and the back side conductors embedded in the polymer layer (78). A stacked semiconductor component (96) includes a plurality of components (90-1, 90-2, 90-3) having aligned conductive vias (58) in electrical communication with one another.
