Class Information
Number: 438/177
Name: Semiconductor device manufacturing: process > Making field effect device having pair of active regions separated by gate structure by formation or alteration of semiconductive active regions > Having schottky gate (e.g., mesfet, hemt, etc.) > Closed or loop gate
Description: Process for making a Schottky field effect transistor wherein the gate electrode is configured such that it closes upon itself to thereby totally surround one of the device active regions.
