IPC: H01L21/027
Filed: 1987-07-05
Abstract: Positive-working photoresist elements are 
protected against reflection of activating radiation from 
the substrate by incorporating of certain butadienyl dyes 
in a photoresist layer, an anti-reflective layer or a 
planarizing layer. These dyes have superior resistance to 
thermal degradation or volatilization at temperatures of 
as high as 200°C or more. The dyes also exhibit good 
solubility in solvents commonly employed in processing 
semiconductor devices, thus permitting the dyes to be 
incorporated in photoresist elements in an amount 
sufficient to prevent resist image distortion caused by 
backscattered or reflected light.

IPC: B23K26/073
Filed: 1987-01-19
Abstract: An improved optical beam integration system for homo­
genizing a nonuniform radiant energy beam having a nonuni­
form beam intensity profile characteristic. The optical beam 
integration system comprises a first crossed cylindrical lens 
structure, a second crossed cylindrical lens structure, and a 
focusing lens interposed between a radiant energy source 
and an image or work plane. The nonuniform radiant energy 
beam from the radiant energy source refracts sequentially 
through the first and second crossed cylindrical lens struc­
tures and the focusing lens so as to produce a homogenized 
beam which forms an image in the work plane. The work 
plane is at a constant distance from the optical beam integra­
tion system. Preferably, the optical beam integration system 
is adjustable for selectively setting the size of the image prod­
uced by the homogenized beam in the work plane. The opti­
cal beam integration system is also preferably adjustable so 
that the aspect ratio of the image produced by the homo­
genized beam in the wortk plane can be selectively set. As a 
result, the effectiveness and flexibility of semiconductor pro­
cessing by means of an ultraviolet excimer laser, for 
ample, are substantially improved.

Title: Plate feed apparatus
IPC: B65G59/08
Filed: 1988-11-14
Abstract: A plate feed apparatus comprises a rotary carrier (22) 
which provides a plurality of semi-spherical gripping 
heads (34) having concave gripping surfaces (36). The 
gripping heads (34) are positioned such that the gripping 
surfaces (36) become flush with the forwardmost plate 
(14a) in a vertically arrayed stack of plates as the 
carrier (22) rotates. Each gripping head (34) is mounted 
to the carrier (22) through a hollow bellows (40) and 
vacuum air drawn into a hole (37) in the gripping face 
passes though the bellows. When the vacuum increases, 
due to the forwardmost plate (14a) in the stack being 
pulled up against the gripping head, the bellows (40) 
collapses and pulls the forwardmost plate away from the 
stack. Rollers (42), which extend beyond the periphery 
of the carrier (22), urge the stack away from the gripping 
head (34) immediately before they become aligned. The 
vacuum then pulls the forwardmost plate (14a) away from 
the stack and into contact with the gripping head (34) 
before the bellows (40) collapses thereby increasing 
the gap between them. Vacuum is provided to the gripping 
head (34) through a passageway which opens out of an 
opening (46) in the carrier (22). A first sector plate 
(48), which is journaled on the carrier axle (26) but 
does not rotate with the carrier, has a slot (50) passing 
through it which overlies the opening (46) in the carrier 
when they are aligned. A second sector plate (52), which 
 
 
overlies and is attached to the first sector plate (48), 
has a hole (54) in it which opens into the slot (50) 
in the first sector plate. A vacuum tube (56) extends 
between this opening and a vacuum source.

Abstract: UV-Entkeimungsgeräte werden zur Entkeimung von Flüssig­
keiten und/oder Gasen mittels UV-Strahlung eingesetzt. 
Der wirksame Einsatz zur Entkeimung von Medien mit 
schwankender bzw. höherer Temperatur, insbesondere 
von Warmwasser, scheitert daran, daß das Emissions­
spektrum der Quecksilber-Niederdruckdampfstrahler 
direkt von der Betriebstemperatur und auch von der 
Umgebungstemperatur abhängig ist. Schwankungen der 
Betriebstemperaur führen einerseits zu einer Ver­
ringerung der entkeimenden Strahlung und anderseits 
zur Auslösung von intralzellulären Reparaturmechanis­
men.  
     Bei der Erfindung ist vorgesehen, den Dampfdruck des 
Quecksilbers der verwendeten Strahler bei Änderungen 
der Wandtemperatur der Strahler weitgehen konstant 
zu halten. Dadurch ist das UV-Emissionsspektrum der 
Quecksilber-Niederdruckdampfstrahler auch bei schwan­
kenden Betriebstemperaturen weitgehend stabilisiert, 
 
 
so daß erstmals die bakteriziede UV-Leistung (Emis­
sion der Linie 254 nm) über einen weiten Variations­
bereich der Betriebstemperatur nahezu konstant gehalten 
werden kann. Gleichzeitig wird die bei herkömmlichen 
Niederdruckstrahlern mit steigender Temperatur ein­
hergehende Erhöhung der UV-A-Emission unterbunden, 
welche die zellulären Reparaturmechanismen aktiviert.
