A side wall masked isolation (SWAMI) technique for isolating active regions on an integrated circuit involves reducing the "bird's beak" structure. The technique involves forming an isolation recess in the substrate, and then lining the recess with a layer of silicon dioxide, and then a layer of silicon nitride. Then, oxide spacers are formed on each of the sidewalls of the recess. The recess is then anisotropically etched until the substrate at the bottom of the recess is exposed. This etch process involves removing portion of both the silicon dioxide and the silicon nitride layers formed at the bottom of the recess. Subsequently, a layer of polycrystalline silicon material is deposited in the recess and is then etched back and oxidized to form a field oxide. Since the polycrystalline silicon is oxidized, the result is negligible oxide encroachment resulting in a reduction in the "bird's beak" structure.

Cyclodextrin derivatives and inclusion complexes having increased solubility and stability are provided. Cyclodextrin derivatives include amino and other modified cyclodextrins, and linked cyclodextrins. Inclusion complexes comprising the foregoing cyclodextrins, and processes for making the cyclodextrin derivatives are disclosed. Also disclosed are cyclodextrin derivatives comprising otherwise substituted or unsubstituted cyclodextrins covalently bonded to agents such as pharmaceuticals. The covalent bond, when broken, yields the agent in active form. Pharmaceutical compositions and methods of treating an animal host are also described, as well as chromatographic compositions and a method for separating racemic mixtures.

One embodiment discloses receiving a number of parameter values for a multi-component circuit. From the received parameter values, a number of parasitic values for various components in the multi-component circuit are determined. For example, parasitic resistor values and parasitic capacitor values for transistors in the multi-component circuit are determined. The parasitic resistor values and parasitic capacitor values are used in simulating the multi-component circuit. According to a disclosed embodiment, a layout of the multi-component circuit is then generated that results in parasitic values that are the same as the parasitic values already used in simulating the multi-component circuit. As such, the parasitic values of the multi-component circuit have already been taken into account in the initial circuit simulation and there is no need to extract the internal parasitics of the multi-component circuit for further circuit simulations.

In one disclosed embodiment, a number of parameter values for an RF MOSFET are received. Examples of parameter values are style, bulk contact, finger width, finger length, number of fingers, current, and slice parameter values. From the received parameter values, a number of parasitic values for a subcircuit model of the RF MOSFET are determined. For example, parasitic resistor values and parasitic capacitor values of the RF MOSFET are determined. The parasitic resistor values and parasitic capacitor values are used in simulating the circuit comprising the RF MOSFET. An RF MOSFET layout is then generated that results in parasitic values that are the same as the parasitic values already used in simulating the circuit comprising the RF MOSFET. As such, the parasitic values of the RF MOSFET have already been taken into account in the initial circuit simulation.
