Abstract: Production of a trench capacitor comprises a preparing a substrate having a surface in which a trench is formed and having an upper region, a lower region and a sidewall; inserting a dopant through the trench side wall in the lower region of the trench. Method also involves forming a mask layer on the trench side wall of the lower region of the trench; depositing nanocrystals on the mask layers so that the crystals cover a first part of the mask layer and expose a second part of the mask layer; etching the mask layer to expose the trench side wall; etching the substrate in the lower region of trench using a structured mask layer; removing the structured mask layer (110) by etching; forming an insulation layer on the trench side wall; depositing a conducting trench filling in the trench on the insulation layer as inner capacitor electrode; and forming a transistor which is connected to the conducting trench filling to control the trench capacitor.  Preferred Features: An insulation collar is produced in the upper region of the trench on the side wall before the side wall is roughened. The mask layer is formed using LPCVD nitride deposition.

IPC: A63H18/00
Filed: 1996-11-21
Granted: 1997-12-11
Abstract: The method involves performing a model car race and determines the winner of a series of several individual races.  The parameters for the series of races are input into a device, and include the participant number and identification, the length of the course, the number of laps or the time of the race, and the number of points for the race losers.  The input parameters also include the number of bonus points for breaking a record, the bonus points for the fastest, second and third fastest laps in a race, the number of penalty points for a false start and the number of possible false starts before disqualification.  The device calculates the number of the race to be driven from the number of participants.  The device starts after a signal that the drivers are ready and detects, via sensor signals generated in the track, the lap times and the number of laps remaining for each model car.  From the input parameters the device calculates the points obtained by each participant, producing a list showing the series winner, after all races are driven.
