An ultralong time constant time measurement device includes elementary capacitive elements that are connected in series. Each elementary capacitive element is formed by a stack of a first conductive region, a dielectric layer having a thickness suited for allowing charge to flow by direct tunnelling effect, and a second conductive region. The first conductive region is housed in a trench extending from a front face of a semiconductor substrate down into the semiconductor substrate. The dielectric layer rests on the first face of the semiconductor substrate and in particular on a portion of the first conductive region in the trench. The second conductive region rests on the dielectric layer.

Fabrication of an integrated circuit includes forming a photoresist layer over a substrate. Target regions defined on the substrate are exposed using a reticle that defines a first exposure window for a first doped structure of a first type; the first exposure window has a first plurality of openings and a first plurality of dopant blocking regions. A respective exposure dose for each of the target regions is determined by an exposure map and provides controlled variations in the size of the first plurality of openings across the plurality of target regions. Subsequent to the exposure and to developing the photoresist, a dopant is implanted into the substrate through the first plurality of openings.

A display device includes a display panel and a first protective substrate positioned under the display panel and including a first sub-region and a second sub-region positioned at a side of the first sub-region. A thickness of the first protective substrate in the first sub-region is greater than a thickness of the first protective substrate in the second sub-region.

An interposer for assembly with a semiconductor die and methods of manufacture are disclosed. The interposer may include at least one passive element at least partially defined by at least one recess formed in at least one dielectric layer of the interposer. The at least one recess may have dimensions selected for forming the passive element with an intended magnitude of at least one electrical property. At least one recess may be formed by removing at least a portion of at least one dielectric layer of an interposer. The at least one recess may be at least partially filled with a conductive material. For instance, moving, by way of squeegee, or injection of a conductive material at least partially within the at least one recess, is disclosed. Optionally, vibration of the conductive material may be employed. A wafer-scale interposer and a system including at least one interposer are disclosed.

A thick-film resistor in a thick-film printed substrate, the resistance of which is maintained at an appropriate value, is disclosed. In a thick-film printed substrate formed by printing a thick-film conductor and a resistor of lanthanum boride type on a ceramic substrate and then sintering, an intermediate resistor layer of lanthanum boride type is provided between the thick-film conductor and the resistor of lanthanum boride type. Reaction of glass composition contained in the thick-film conductor is suppressed, and resistance abnormality is prevented during sintering by causing the intermediate resistor layer of lanthanum boride type to be interposed.

摘要:
In a microelectronic package of the type where Si-based integrated circuits are eutectically attached to a Pd/Au-based thick film conductor, a method of reducing the potential for thermal runaway is taught. The method involves increasing the surface area of the Pd to lower the Vbe rating. This reduces the potential for thermal runaway in subsequent integrated circuit operation. It has also been found that increasing the particle size of the Au component further decreases the Vbe rating.
