Abstract: A half bridge circuit includes two GaN high electron mobility transistors (HEMT). A driver circuit generates a high side and low side driver signals corresponding to square wave. A driver deadtime is the period between during which both driver signals are low. A half bridge adjustment circuit is coupled between the driver and the half bridge circuit and generates a modified high side driver signal and a modified low side driver signal, each including a transition from a low voltage to an intermediate voltage during the corresponding deadtime and a transition from the intermediate voltage to a high voltage at an end of the corresponding deadtime. The half bridge adjustment circuit drives the gate terminals of the high side and low side transistors with the modified high side and low side driver signals.

Abstract: A substrate includes a center portion and a peripheral portion connected to the center portion by a flexible coupling region. A first die is mounted to an upper surface of the substrate at the center portion and a second die is mounted to the upper surface of the substrate at the peripheral portion. A heatsink includes a base plate, fins extending from an upper surface of the base plate and tabs extending from a lower surface of the base plate. The tabs of the heatsink are mounted to the upper surface of the substrate at the center portion, and the lower surface of the base plate is thermally coupled to a back of the first die. The peripheral portion is folded relative to the center portion at the flexible coupling region. An outer surface of the fin of the heatsink is thermally coupled to a back of the second device.

Abstract: Packaged electronic device (50; 70), having a C-shaped leadframe (52) including a base section (52A) and a pair of transverse sections (52B) extending transversely to the base section. A first die (11A, 60) and a second die (11B, 60) have a first contact region (27) at a first main surface and a second contact region (29) at the second main surface; the first main surfaces of the first and the second dice are attached to a first face (58) of the base section (52A) of the leadframe (52). A first lead (53) is coupled to the second contact region (29) of the first die (11A, 60) and has a first external contact portion (53B). A second lead (53) is coupled to the second contact region (29) of the second die and has a second external contact portion (53B). A packaging mass (52) surrounds the leadframe (52), the first lead and the second lead (53), embeds the first and the second dice (11A, 11B, 60) and extends level with the base section (52A) and with the transverse sections (52B) of the leadframe (52) as well as with the external contact portions (53B) of the leads.

Abstract: Methods, systems, and apparatuses for normally off HEMT are provided, including for in situ plasma treatment before Al2O3 deposition for improved on on-hydrogen-based resistance. An exemplary method may include providing a wafer comprising a AlGaN layer and a p-GaN layer; etching the p-GaN layer to form a p-GaN gate; depositing a first aluminum oxide layer over the p-GaN gate; depositing a silicon dioxide layer over the aluminum layer; etching the silicon dioxide layer and the aluminum oxide layer to expose a first portion of the AlGaN layer starting a first distance from the p-GaN gate; treating the first portion of the AlGaN layer with an in-situ hydrogen-based plasma treatment, wherein the in situ plasma treatment deactivates magnesium in the first portion of the AlGaN layer; and forming at least a first normally-off HEMT, wherein the gate of the normally-off HEMT is the first p-GaN gate.
