Latest Patents

Bharat's latest patents include a semiconductor multichip module package designed with improved thermal performance and reduced size, as well as enhanced moisture resistance. This innovative multichip module features a substrate that accommodates several flip chips and other semiconductor dies on one surface. The design incorporates vias that extend through the substrate, connecting the flip chip bottom electrodes to solder ball electrodes located at the substrate's bottom. Additionally, passive components are mounted on the substrate's top and linked to further vias that connect to respective ball contacts at the bottom. In one embodiment, the bottom surfaces and electrodes of the dies are insulated, while their tops are connected by a moldable conductive layer. Another embodiment includes an insulation cap that may be finned to enhance thermal properties. The passive components are oriented to have their longest dimension perpendicular to the substrate surface, positioned between the fin valleys.

Another notable patent is the chip-scale package, which consists of a substrate with upper and lower surfaces. The upper surface is defined by a periphery with spaced apart side edges and front and rear edges. A power semiconductor die is placed on the upper surface, featuring a top surface with at least one metalized surface and a bottom surface. The design includes a plurality of conductive pads located only at one side edge of the substrate, along with wire bonds extending from the metalized surface to these conductive pads.
