Abstract:
A MESFET transistor including source, gate, and drain structures, said transistor comprising:a substrate defining a planar surface; a doped channel region in said planar surface, said channel region being elongated in a source-to-drain conduction direction and defining source and drain ends; an electrically conductive gate conductor defining upper and lower surfaces, said gate conductor having first and second edges spaced apart in said source-drain conduction direction, which first and second edges of said gate region are nearer to said source and drain ends of said channel region, respectively, said second edge of said gate conductor being spaced about 1.8 microns from said drain end of said channel region; a source electrically coupled to said source end of said channel region; a drain electrically coupled to said drain end of said drain region; an electrically conductive field plate connected to said upper surface of said gate conductor and extending about 1.3 microns from said second edge of said gate conductor toward said drain end of said channel region.
