High voltage GaN HEMT developed for the high frequency operation in a low-inductance source terminal TO220 package
The TPH3002PS is a 600V EZ-GaN™ HEMT for high frequency operations from Transphorm. Manufactured by Fujitsu and assembled in a TO220 package, it features the Quiet-TabTM scheme which increases switching speed by 200%. With a 7.5ns turn-on and a 10ns turn-off, the TPH3002PS has a higher switch frequency than the best CoolMOS.
The TPH3002PS is based on a cascode configuration of a GaN on Silicon HEMT transistor to hold the high voltage and a standard low voltage MOSFET to drive high frequency and to make a normally-off transistor from a normally-on GaN HEMT.
The device is assembled in a TO220 package for an easy integration in converter electronic system. Moreover, it integrates a Quiet-Tab™ and a Gate-Source-Drain (GSD) pin-out arrangement in order to reduce the parasitic inductance and capacitance in high frequency and to allow 200% increase in switching speed compared to traditional TO-220.
The report presents a deep technology analysis of the packaging and the components with TEM images of the complex GaN epitaxy layer stack and transistor structure.
It also includes production cost analysis and overall comparison with GaN Systems GS66508P 650V HEMT.

This overcomes issues with further scaling planar transistors. 3D transistors provide fully depleted operation and tighter channel control through conducting channels on three sides of a vertical fin. This enables high drive currents and improved switching performance. 3D transistors can operate at lower voltages than planar transistors, reducing power consumption by over 50% while maintaining or improving performance. They will allow continued transistor scaling per Moore's Law and are needed for future generations of chips.
Finfet
The document discusses the history and development of FinFET transistors. FinFETs were developed to overcome short channel effects by using a thin silicon fin as the channel between the source and drain. This allows the gate to control the channel from both sides and edges of the fin. FinFET fabrication involves depositing fins using electron beam lithography then depositing a gate material around the fins. FinFETs suppress short channel effects and allow for higher density transistors compared to planar MOSFETs, though they also have some disadvantages like reduced mobility.
Finfet; My 3rd PPT in clg
FINFET is a type of non-planar transistor with a conducting channel that is wrapped by a thin silicon fin. It was developed to overcome short channel effects seen in planar MOSFETs as transistors continue to shrink. Key aspects of FINFETs include the fin structure which allows gate control of the channel from both sides and the top, reducing leakage currents. Fabrication involves depositing fins and wrapping a gate material around them. FINFETs have been shown to effectively suppress short channel effects even at very small gate lengths, but come with increased manufacturing complexity and potential reliability issues compared to planar transistors.
