IPC: G03F7/16
Filed: 1987-10-13
Granted: 1992-10-13
Abstract: ABSTRACT OF THE DISCLOSURE      Disclosed is a process for forming a planarized multilevel chip wiring structure.  Starting from a substrate having thereon at least a metal stud serving as vertical wiring between two levels of metallization, a quartz layer is deposited, obtaining a non-planar structure.  A thick planarizing photoactive photoresist is applied.  The photoresist is converted by silylation process into a silicate having substantially the same etch rate as that of quartz.  Silylation is accomplished by, for example, subjecting the resist to a bath of hexamethyldisilazane, hexamethylcyclotrisilazane, octamethylcyclotetrasilazane, N,N,dimethylaminotrimethylsilane or N,N,diethylaminotrimethylsilane, for a period of time determined by the thickness of the resist.  Unwanted portions of the silylated resist and quartz are etched back at 1:1 etch rate ratio to the level of the stud.

Title: Switching ac voltage regulators
Inventor: MCGUIRE THOMAS B
IPC: G05F1/24
Filed: 1988-05-17
Granted: 1991-05-14
Abstract: ABSTRACT A switching AC voltage regulator including a transformer, two solid state AC switches, and sensing means controlling the switches to produce the desired output voltage.  The two switches conduct alternately and are switched at a rate much higher than the frequency of the regulated AC voltage.  When the first switch is activated, the transformer is shorted out, causing the output of the transformer to equal the input.  When the second switch is activated, normal transformer action occurs, creating an output voltage either higher or lower than the input, depending on the transformer arrangement. The duty cycle of the switches is varied to provide precise control of the output voltage.

Title: Optic switch and speed sensor
Inventor: EMO STEPHEN M
IPC: G01D5/353
Filed: 1989-02-03
Granted: 1993-10-19
Abstract: ABSTRACT       An electro-optic speed sensor for sensing the speed of rotation of a rotating unit which includes an optical switch transducer for sensing disturbances in a magnetic field caused by the passage of a rotating magnetic sensing wheel on the rotating member.  The optical switch transducer uses a Faraday material and provides its signal by rotating the polarity of polarized light from a first source of light having a first bandwidth while allowing a second source of light having a second bandwidth to pass through unaffected.          The first and second sources of light are thereafter, reflected within the transducer.  The disturbances in the magnetic field generate an optical signal resulting from changes in the Faraday rotation.  A photodetector receives the light from the first source to develop an operational signal corresponding to the speed of rotation of the rotating member and light from the second source to check on the continuity of the sensor system.
