摘要:
The present invention relates to polycyclic polymers, methods for producing polycyclic polymers, and methods for their use as photoresists in the manufacture of integrated circuits. In one embodiment, the present invention relates to photoresist compositions formed from the polymerization of at least one halogenated polycyclic monomer or hydrohalogenated polycyclic monomer. In another embodiment, the present invention relates to photoresist compositions formed from the co-polymerization of at least one halogenated polycyclic monomer or hydrohalogenated polycyclic monomer with at least one non-halogenated polycyclic monomer. Additionally, the present invention relates to methods by which to post-treat such photoresist compositions in order to obtain one or more of: (1) a reduction in optical density of the polymer composition; and (2) a reduction in the amount of residual metal and/or monomer in the polymer composition. Also disclosed are catalyst systems for use in producing the photoresist compositions of the present invention which permit molecular weight control of the photoresist products.

A modified hybrid Hall effect device is provided which is the combination of a conventional Hall effect device and a second Hall effect device having a Hall plate coupled to a ferromagnetic layer. The hybrid Hall effect device can be used to determine the independent magnetic field vector components comprising a vector magnetic field, such as for determining the x and the z components of a magnetic field, or for measuring the total magnitude of a vector magnetic field of any orientation. The modified Hall Effect device can be adapted for use as a magnetic field sensor for the detection of macroscopic objects that have associated magnetic fields, or for microscopic objects that have been tagged by microscopic magnetic particles. In one specific form, a plurality of hybrid Hall devices are electrically connected together to form an array in which a plurality of rows of hybrid Hall devices are electrically coupled to each other along a current axis, and the array is used for the detection of microscopic objects.

摘要:
A spin injected diode suitable for nonvolatile memory applications is made of a semiconducting channel capable of carrying current, a single ferromagnetic layer, and a barrier layer between the semiconducting channel and the ferromagnetic layer to protect the integrity of the semiconducting layer and to inhibit interdiffusion of the ferromagnetic material and the semiconductor. During diode readout the output modulation of the diode can be sensed either as the interface resistance between the semiconducting channel and the ferromagnetic layer, or as the output voltage between the semiconducting channel and the ferromagnetic layer when flowing current through the channel and not through the interface. Two of these spin injected diodes can be combined to form a spin injected field effect transistor. This transistor has a first ferromagnetic layer having a first coercivity and a second ferromagnetic layer having a second coercivity smaller than the first coercivity which are spaced apart. A gate is situated between the ferromagnetic layers and includes an insulating layer situated below the gate and between the two ferromagnetic layers. A semiconducting channel layer beneath the first and second ferromagnetic layers and beneath the gate forms a low impedance electrical path between the first and second ferromagnetic layers when a control signal is applied to the gate and a high impedance electrical path between these ferromagnetic layers at all other times. A key component is a barrier layer between the semiconducting channel and the two ferromagnetic layers which performs the same functions as in the diode.
