Patent ES-466901-A1 (ES)
Title: Total dielectric isolation utilizing a combination of reactive ion etching, anodic etching, and thermal oxidation
IPC: H01L21/306
Filed: 1978-02-11
Abstract: A process which utilizes an anodized porous silicon technique to form dielectric isolation on one side of a semiconductor device is described. Regions of silicon semiconductor are fully isolated from one another by this technique. The starting wafer typically is predominantly P with a P+ layer thereon. A P or N layer over the P+ layer is formed thereover such as by epitaxial growth. The surface of the silicon is oxidized and a photoresist layer applied thereto. Openings are formed in the photoresist. Openings are formed in the silicon dioxide using the photoresist as a mask and appropriate etching techniques. The openings in the silicon dioxide define the regions to be etched by reactive ion etching. Reactive ion etching is accomplished at least down to the P+ region. The structure is then subjected to the anodic etching technique which preferentially attacks the P+ layer to form porous silicon throughout the P+ layer. The structure is then placed in a thermal oxidation ambient until the porous silicon layer has been fully oxidized to silicon dioxide. The openings through the surface layer are filled up with oxide to fully isolate the P or N surface layer.

Title: Character selection for single element printer
IPC: B41J7/50
Filed: 1978-03-16
Abstract: There is disclosed a selection mechanism for a single element printer comprising an operating link connected with the print element for the driving rotation thereof and having a first and a second input portion, and a modifying member having the link mounted thereon for pivotal motion about the first input portion. A cam follower is provided on the modifying member for engagement by a case shift cam, which is operable independent of the print shaft, to shift between a pair of locations in either of which a first character selection means cooperates with the modifying member to position the latter in either of two distinctive positions so that the first input portion of the operating link is positionable to any of four positions. The second input portion of the link is associated with a second character selection means for positioning the link to any of a plurality of pivotal positions relative to the first input portion thereof. The selection mechanism is simply constructed by connecting all the input means to a single operating link mounted inclusively on the carrier and, therefore, the selection mechanism can be manufactured at a low cost. Maintenance and adjustment of the printer can also be greatly minimized.
