Lead, wiring member, package part, metal part provided with resin and resin-sealed semiconductor device, and methods for producing same

A semiconductor device and manufacturing method therefor, provided with the aims of constraining resin burr formation while having good electric connectivity and joining strength, and LED device, provided with the aim of improving adhesion between silicon resin and leads while having good luminescent characteristics. For these purposes, an organic film is formed through self-assembly by functional organic molecules at surface border regions of outer leads of a QFP. The functional organic molecules consist of a first functional group bonding with metals, a principal chain, and a second functional group inducing hardening in thermosetting resins. The principal chain consists of a glycol chain, or else of a glycol chain and one or more among methylene, fluoromethylene, or siloxane chains. The principal chain also preferably includes one or more among a hydroxyl radical, ketone, thioketone, primary amine, secondary amine, and aromatic compounds.

Vertical ballast technology for power HBT device
09911836 · 2018-03-06 · ·

Power amplification devices are disclosed having a vertical ballast configuration to prevent thermal runaway in at least one stack of bipolar transistors formed on a semiconductor substrate. To provide a negative feedback to prevent thermal runaway in the bipolar transistors, a conductive layer is formed over and coupled to the stack. A resistivity of the conductive layer provides an effective resistance that prevents thermal runaway in the bipolar transistors. The vertical placement of the conductive layer allows for vertical heat dissipation and thus provides ballasting without concentrating heat.

Alkali silicate glass based coating and method for applying

A coating for reducing interaction between a surface and the environment around the surface includes an alkali silicate glass material configured to protect the surface from environmental corrosion due to water or moisture. The alkali silicate glass material is doped with a first element to affect various forms of radiation passing through the coating. The electromagnetic radiation is at least one of ultraviolet, x-ray, atomic (gamma, alpha, beta), and electromagnetic or radio wave radiation. The coating may also be used to protect a solar cell from the environment and UV rays while retransmitting received light as usable light for conversion into electrical energy. The coating may also be used to prevent whisker formation in metal finishes of tin, cadmium, zinc, etc.
