Title: Method of optimizing photoresist contrast
IPC: G03F7/26
Filed: 1990-05-25
Abstract: The contrast of a photoresist layer (18) used in a 
lithographic process for a given light (17) source is 
optimized by determining the nonlinear relationship of the 
photoresist (18) contrast with regard to the thickness 
thereof and then placing over a substrate (20) a thickness 
of photoresist (18) corresponding to a desired value of 
contrast indicated by the nonlinear relationship (14) of 
contrast (14) with photoresist thickness. The nonlinear 
contrast (14) with regard to photoresist (18) thickness 
function is a damped, sinusoidal like function (14) with 
the difference between maxima (15) and minima (16) 
contrast values decreasing as the photoresist thickness 
increases and with higher absolute maxima (15) values for 
contrast as photoresist (18) thickness decreases. The 
amount of light (17) needed to fully expose a given 
thickness of photoresist (18) also varies with the 
photoresist (18) thickness in a sinusoidal like manner 
(24) and a phase difference may exist therebetween and the 
sinusoidal like contrast versus photoresist thickness 
function (14).

IPC: B29C48/495
Filed: 1990-12-21
Abstract: Method, apparatus, and films, related to coextrusion of heat-sensitive polymer materials. The sensitive melt stream element (12) is encapsulated in a second polymeric melt stream element (16). Transport means (36) is preferably employed between the encapsulating means (20) and the die (42). A third melt stream element (68) is joined to one or both opposing surfaces (70) of the second melt stream element (16) between the encapsulating means (20) and the die (42). In the die (42) the encapsulated melt stream element (12) becomes an interior layer (46) between encapsulating layers (48A, 48B) derived from the second melt stream element (16). The third melt stream element (68) forms layers (72, 74) positioned outwardly of the encapsulating layers (48A, 48B). The positioning, on the interior of the extrudate, of edges (54) of layer (46) is adjusted independently of the combined thicknesses of a layer derived from the third melt stream element (68) and an adjacent layer (48). <IMAGE>

Abstract: The drain-to-source voltage and current for programming a selected
nonvolatile memory cell  10  are achieved efficiently by pumping the source  11  of a
selected cell  11  to a voltage less than the voltage  VSS  at the reference-voltage
terminal of the memory cell array while, at the same time, pumping the drain  12  of
the selected cell  10  to a voltage greater than the voltage  VCC , which may be 3V, at

Abstract: A semi-batch process is provided for making a
diene rubber latex. The process involves (a)
providing an amount (12) of an initial liquid batch
composition (11) (containing water, emulsifier and
diene monomer), sufficient to occupy from 50 to 80
volume percent of a pressure reaction vessel (10)
based on the total volume of the vessel, (b) feeding
to the vessel a liquid feed composition (13)
containing diene monomer and initiator, (c)
providing cooling (18) to the vessel to
cool the liquid and vapor therein, and (d) reacting
the diene monomer to a final diene monomer conversion
level of at least 80 mol percent based on the total
moles of diene monomer used in the reaction, and the
final liquid volume level in the vessel being at
least 80 volume percent based on the total volume of
the vessel. The process allows for a high initial
reaction rate which peaks early in the process when
efficient vapor phase cooling is maximized, and
maintains a low latex viscosity throughout the
process thereby providing efficient liquid phase
cooling during latex in the process. The present
process allows for higher levels of production over
batch utilizing the same vessel volume. A rubber
latex is also provided having a narrow particle size
distribution, and a vinyl aromatic-diene rubber graft
copolymer is provided exhibiting certain advantageous

Abstract: A multimode electromagnetic wave energy rejection filter
arrangement for a slot waveguide includes at least one system
of series coupled LC-circuits located, at least partly, within
a cavity of the slot waveguide and arranged along a
predetermined line intersecting the wave vectors of
electromagnetic waves to be rejected, the LC-circuits including
lumped elements and the coupling between the LC-circuits being
substantially weak. The LC-circuits may be located, at least
partly, within grooves formed in a wall of the slot waveguide.
As applied to a heating apparatus employing high frequency
electromagnetic wave energy or microwave energy for heating
dielectric materials, the series coupled LC-circuits are
arranged along a closed line which envelopes the access opening
in a body of a multimode resonator heating chamber, in which
the high frequency electromagnetic wave energy is employed for
heating. By optimizing the parameters of the system of series
coupled LC-circuits it is possible to provide rather low
transmittance for a wide range of angles of incidence of waves,
as well as to minimize the transmittance dependence on the
angles of incidence of these waves. The later enables to
achieve high protection against leaks of electromagnetic energy
from the resonator heating chamber of a heating apparatus, for
example, of a domestic microwave oven.
