IPC: H01L21/302
Filed: 1998-07-13
Granted: 2000-09-11
Abstract: The present invention concerns a method for optimising the etching rate of a polycrystalline layer having a predetermined composition comprising at least two chemical species arranged in the form of grains and grain boundaries, this layer having to be formed on a semiconductor substrate by a deposition process whose parameters have to be determined, and by a etching process with a reactive agent capable of reacting with the preponderant species in the layer. This method defines a structure parameter representing the grain boundary density of the layer, and comprises a step consisting in determining the smallest structure parameter value from among different samples having the predetermined composition, this value considered as that which optimises the etching rate.

Granted: 2000-11-01
Abstract: An internal synchronous signal generating circuit outputs the internal synchronous signals ICLK1, ICLK2. A burst counter outputs an internal column address signal IADD and the lowermost internal column address signal IY0. A first and second D-F/Fs input an output of the input buffer and drives a first write bus (WBUS) in synchronization with the ICLK1. An inverting element inputs IY0. Inverting elements input outputs of the first and second D-F/Fs and drives a second write bus (WBUS). A transistor TG1 is connected between the first WBUS and second D-F/F. The gate is connected to the output of the first inverting element. A transistor TG2 is connected between the output of the second inverting element and second D-F/F with IY0 connected to the gate. A column decoder inputs IADD and outputs a column switch YSW. A plurality of sense amplifiers input the YSW and the second WBUS. A memory cell array is connected to the sense amplifiers through a bit line. By using this device, the maximum consumptive current or an average consumptive current in the burst can be reduced.

Title: Method for operating a high power electron beam
Inventor: BAHR MARTIN
IPC: H01J37/305
Filed: 1998-10-23
Granted: 2001-02-21
Abstract: The invention pertains to a method for the operation of a high-power electron beam for the vaporization of materials in a target. With this method, static and dynamic deflection errors are corrected. First, the static and dynamic deflection errors are ascertained by means of a teach-in process for concrete spatial coordinates and concrete frequencies of the deflection currents and stored in a memory. For the later operation, this stored data is used in such a way that input geometric data for the incidence points of the electron beam is automatically recalculated into corrected current values which bring about the exact incidence onto the input points. A corresponding procedure takes place with the input of frequencies for the deflection current. The input frequencies are automatically corrected in terms of frequency and amplitude in order to eliminate the frequency-dependent attenuation effects. Both in the correction of the static and in the correction of the dynamic deflection errors it is guaranteed by suitable interpolation methods that even the spatial coordinates and frequencies not considered in the teach-in process are taken into account. Finally, a method is specified with which it is possible by mere specification of a power distribution on a crucible surface to control the electron beam such that the specified data is satisfied.
