Field-effect type compound semiconductor device and method for fabricating the same

   
   

At least a channel layer and an etching stopper layer are provided on a semiconductor substrate in order, a gate electrode that Schottky-contacts the etching stopper layer is provided on the etching stopper layer, and InGaP having an In composition ratio of 0.66 through 0.9 is used as the etching stopper layer in a field effect type compound semiconductor device.

По крайней мере слой канала и слой затвора вытравливания обеспечены на субстрате в заказе, электроде полупроводника строба который Счюотткы-kontaktiruet слой затвора вытравливания обеспечен на слое затвора вытравливания, и InGaP имея в структурный коэффициент 0.66 через 0.9 использовано как слой затвора вытравливания в составного прибора на полупроводниках типа влияния поля.
