Title: Method of forming conductive region of monolithic integrated semiconductor device and high packing density semiconductor device produced by same method
Inventor: RIHIARUTO PERUSHIFUARU
IPC: H01L23/52
Filed: 1983-02-18
Abstract: In the manufacture of semi-custom integrated circuits silicon wafers with P and N or N and P structures are used, and interconnections to establish a specific application must be created. Unlike currently known technologies, electrically conductive film with standardized openings made according to a pre-arranged raster must be deposited on the silicon wafer. Subsequently the conductive film, will be removed from between the openings directly or indirectly by means of electromagnetic radiation in order to produce the required circuit configuration. A laser beam is particularly appropriate for this since it can be positioned and controlled, and can be used directly for the exposure of a photosensitive film. The creation of insular conductive film is then achieved through a photo- etch technique. By use of this process, an expensive customer specific photo mask can be avoided. A semiconductor device manufactured according to this process exhibits in its conductive film a regular arrangement of openings which are able to form the ends, sides or corners of insular conductive film.

Title: Heater
Inventor: MISHIMA MOTOMICHI
IPC: F24C7/02
Filed: 1984-02-14
Abstract: PURPOSE:To prevent a failure in toasting due to heating by a method wherein a scaled disk provided around the rotary shaft of a timer is rotated by displacing a bimetal adopted to sense the temperature in a toasting chamber so that the setting of a heating time is automatically corrected. CONSTITUTION:When slices of bread are toasted continuously by an oven toaster, a first slice may be toasted in a color to the user's liking by adjusting a knob 1 of the timer to, for example, the medium position. Then, when the toasting of the first slice is finished, the bimetal 13 bends by sensing the temperature in the toasting chamber 7 and at the same time, the toasting adjusting the sealed disk 11 is rotated to the left to change its position. Thus, when a second slice and onward are toasted by adjusting the knob 1 of the timer to the medium position in the same manner as in the case of toasting the first slice, the time for toasting the second slice and onward is corrected with respect to the time for toasting the first slice since the medium position on the scaled disk 11 is displaced to the left from the time when the first slice was toasted and the time set for the timer is shortened. As a result, all of the slices are toasted in the same toasting degree.
