Latest Patents

One of Duinkerken’s patents describes a method for manufacturing a semiconductor device suitable for surface mounting. Semiconductor elements are connected in a row using conductive strips, then enveloped in protective material and separated into individual devices. Conductive layers applied to the devices’ side faces contact portions of the strips, forming connection conductors.

Another patent concerns manufacturing semiconductor devices with pn junctions. Depressions formed in a semiconductor slice cut through a pn junction, dividing it into mutually insulated portions. An insulating layer is applied to the depression walls before the slice is separated into individual semiconductor bodies.
