Design structures for high-voltage integrated circuits. The design structure, which is formed using a semiconductor-on-insulator (SOI) substrate, may include device structure with a semiconductor body positioned between first and second gate electrodes. The first and second gate electrodes and the semiconductor body may be formed from the monocrystalline SOI layer of the SOI substrate. A dielectric layer separates each of the first and second gate electrodes from the semiconductor body. These dielectric layers are formed by defining trenches in the SOI layer and filling the trenches with a dielectric material, which may occur concurrently with a process forming other device isolation regions.

A method of protecting devices within an integrated circuit during electro-static discharge (ESD) testing using an ESD test system is provided. The method includes applying a direct current (DC) bias voltage to an input of at least one device of the integrated circuit and applying an ESD simulated signal to at least one other input of the integrated circuit. The applied ESD simulated signal is conducted along a first current path to a first ground, while a low-current signal associated with the at least one device is conducted along a second current path to the second ground. The DC bias voltage is maintained between the input of the at least one device and the second ground at a substantially constant value in response to a signal variation on the second ground that results from the applied ESD simulated signal.

Device structures, fabrication methods, operating methods, and design structures for a silicon controlled rectifier. The method includes applying a mechanical stress to a region of a silicon controlled rectifier (SCR) at a level sufficient to modulate a trigger current of the SCR. The device and design structures include a SCR with an anode, a cathode, a first region, and a second region of opposite conductivity type to the first region. The first and second regions of the SCR are disposed in a current-carrying path between the anode and cathode of the SCR. A layer is positioned on a top surface of a semiconductor substrate relative to the first region and configured to cause a mechanical stress in the first region of the SCR at a level sufficient to modulate a trigger current of the SCR.
摘要:
A lateral diffused metal-oxide-semiconductor field effect transistor (LDMOS transistor) employs a stress layer that enhances carrier mobility (i.e., on-current) while also maintaining a high breakdown voltage for the device. High breakdown voltage is maintained, because an increase in doping concentration of the drift region is minimized. A well region and a drift region are formed in the substrate adjacent to one another. A first shallow trench isolation (STI) region is formed on and adjacent to the well region, and a second STI region is formed on and adjacent to the drift region. A stress layer is deposited over the LDMOS transistor and in the second STI region, which propagates compressive or tensile stress into the drift region, depending on the polarity of the stress layer. A portion of the stress layer can be removed over the gate to change the polarity of stress in the inversion region below the gate.
