Webprocedure begins with a pre-test to determine oxide integrity. In this pre-test, a constant current (typically 1µA) is applied and the voltage sustained across the oxide measured. If the device is “good,” an increasing logarithmic step current [given by Istress = Iprev * F (where F < 3.2)] is applied until oxide failure. Oxide Webgate oxide integrity is achieved with increased oxide breakdown voltages and charge-to-breakdowns, as well as a reduction in oxide charge trapping. This work also demonstrates the feasibility of achieving bulk-comparable gate oxide on TFSOI substrates. INTRODUCTION

WebGate oxide. The gate oxide is the dielectric layer that separates the gate terminal of a MOSFET (metal–oxide–semiconductor field-effect transistor) from the underlying source and drain terminals as well as the conductive channel that connects source and drain when the transistor is turned on. Gate oxide is formed by thermal oxidation of the ... Web本テスト方法は，Gate Oxide Integrity （GOI）によるウェーハ品質評価法に関するものである。GOIはシリコン基板中に存在するCOPを検出するために用いられてきたが，よく知られているように表面に存在する欠陥検出の画で非常に高感度である。
WebOct 1, 1997 · To clarify the influence of crystal-originated "particles" (COPs) on gate oxide integrity (GOI), a new GOI evaluation method has been developed. This method compares the GOI of a metal oxide silicon (MOS) capacitor which includes a COP with a MOS capacitor that is COP-free by measuring the capacitors' I–V characteristics.
