Patent GB-2130718-A (GB)
Title: Improvements relating to methods and apparatus for measuring spermatozoal motility
Inventor: PIKE E R
IPC: G01P5/26
Filed: 1983-09-14
Abstract: A highly collimated light beam 1 is directed onto a sample cell 3 enclosing a sample of sperm solution and reflected therefrom into a microscope 4 and television camera 5. The shape and type of movement of individual spermatozoa is such that the collimated light will only be reflected into the microscope from those spermatozoa which are moving very close to one direction. Images registered by the camera 5 are relayed to an electronic image processor 6 which calculates the rate of movement (and the number, if required) of visible targets moving in one direction between two frames at a known separation, by calculating, e.g. a cross-correlation function for the two line-averaged frames. <IMAGE>

Title: Improvements in or relating to a method for fabricating an MOS device
Inventor: BATRA TARSAIM LAL
IPC: H01L21/60
Filed: 1983-09-22
Abstract: A method for fabricating an integrated circuit semi-conductor device comprised of an array of MOSFET elements having self-aligned or self- registered connections, with conductive interconnect lines 40 is disclosed. The method involves the formation of a substrate 22 of a thick oxide insulation layer 30 surrounding active area openings. A gate electrode 38 within each opening is utilised to provide self- registered source and drain regions 42, 44. The gate may be covered on all sides and on its top surface with a protective layer 62 of nitride or thick oxide. After the formation of the source- drain regions a relatively thin protective layer of etch stopper is applied to the entire chip prior to the application of an upper insulative layer 50. When oversized windows are etched in the upper insulative layer, the etch stopper layer prevents etching of the nitride layer, thus preventing shorts or leaks between conductive and active areas and providing self-aligned contacts with minimum spacing from adjacent conductive areas. In another of the embodiments, a thick layer of oxide provides insulation between the gate, source-drain region and conductive lines. <IMAGE>
