Title: Semiconductor device and field effect transistor
Inventor: OKAMOTO YASUHIRO
IPC: H01L29/778
Filed: 2002-06-17
Abstract: <P>PROBLEM TO BE SOLVED: To provide a contact layer used for a semiconductor device, such as the HJFET etc., that can obtain a low contact resistance without passing through any high-temperatrue annealing step.  <P>SOLUTION: The ohmic-contacted contact layer of a hetero field effect transistor is constituted of a GaN layer 14 and an Al<SB>y</SB>N<SB>(0<y≤)</SB>layer 15 formed on the layer 14. Then ohmic electrodes 1 and 3 are formed on the contact layer. When the transistor is constituted in this way, the transistor can obtain a low contact resistance without passing through any high-temperature annealing step. In addition, since dependency of the contact resistance on the electrode material is low, the low contact resistance is obtained even when a thermally stable material, such as the WSi etc., having a high melting point is used as an electrode material.  <P>COPYRIGHT: (C)2004,JPO
