Abstract:
There is provided a high quality liquid crystal panel having a thickness with high accuracy, which is designed, without using a particulate spacer, within a free range in accordance with characteristics of a used liquid crystal and a driving method, and is also provided a method of fabricating the same. The shape of a spacer for keeping a substrate interval constant is made such that it is a columnar shape, a radius R of curvature is 2 μm or less, a height H is 0.5 μm to 10 μm, a diameter is 20 μm or less, and an angle α is 65° to 115°. By doing so, it is possible to prevent the lowering of an opening rate and the lowering of light leakage due to orientation disturbance.

Abstract:
A means of connecting a plurality of essentially identical active devices is presented for the purpose of multifunction and multiple function operation. These devices, mounted on a chip, are flip-mounted to a circuit motherboard having large passive elements. A push-pull amplifier is presented as an example in which the multiple function operation is the combining of amplifiers whose active devices are on a single chip. The electromagnetic coupling, impedance matching and signal transmission are variously provided by the use of striplines, slotlines, coplanar waveguides, and a slotline converted into a coplanar waveguide.

Abstract:
Chips formed on respective wafers are numbered. A map in which chip positions are correlated with chip numbers is created. A process is specified for each individual chip. A host computer creates processing information from inputted lot information for each individual chip and supplies the created processing information to a processing apparatus. A terminal for receiving various kinds of information, a line terminal, a processing information storage means for storing processing information, and a line interior information storage means are connected to the host computer. Also, a chip-managing computer is connected to the host computer. This chip-managing computer creates maps of chips formed on wafers and creates map information in which device information is correlated with chip numbers assigned to respective chips. A chip information storage means for storing the map information is connected to the chip-managing computer.

A method for fabricating a semiconductor device including carrying out an ion implantation into a predetermined region of a single-crystal silicon substrate to form therein an amorphized ion-implanted layer according to any one of the methods: (A) implanting an ion of an atom serving as carrier into the predetermined region, followed by implanting an ion of an electrically inert atom or molecule into the region, (B) implanting an ion of an electrically inert atom or molecule in the region, followed by implanting an ion of an atom serving as carrier in the region, and (C) implanting an ion of a molecule in which an atom serving as carrier is bonded to an electrically inert atom; annealing the substrate in an inert atmosphere to crystallize the amorphized ion-implanted layer again; and further annealing the substrate in an oxidizing atmosphere to eliminate defects at the interface of the substrate and the ion implantation layer.
Abstract:
An improved alloyed ohmic contact to n-type GaAs is provided utilizing a Si-based metallization of Si/Au/Ni and exhibiting low contact resistivity and high thermal stability. An improved process for fabricating the inventive contact is also provided comprising the step of first depositing the Si film on the GaAs substrate, thereby simplifying the fabrication of monolithically integrated devices, particularly advanced electro-optic devices, by incorporating self-aligned Si-based contacts in the process. A further improvement is provided in the use of a lift-off-defined Si layer as a reactive-ion etch mask to serve as the self-aligned contact in the process, thereby eliminating a critical photolithographic step of aligning the contact metallization.

Abstract:
The disclosure relates to a three dimensional semiconductor structure formed in a semiconductor substrate wherein electrical components, both active and passive, are formed on the substrate surface as well as in grooves formed in the substrate at an angle and extending to the surface. The substrate surface is designed to lie in a predetermined crystallographic plane of the substrate material and the grooves extend in a predetermined crystallographic direction from said plane, this being accomplished by orientation dependent etching.
