Title: Method and apparatus for converting a gap-infested read-in clock into a gap-free-read-out clock
Inventor: LANG HERMANN
IPC: H03L7/06
Filed: 1990-03-21
Abstract: ABSTRACT OF THE DISCLOSURE           An integrated circuit wherein no disturbances due to spikes occur is provided for converting a gap-infested clock into a gap-free clock.   In a phase-locked loop the frequency of a read-in clock is supplied to a phase discriminator via a frequency divider and the frequency of a read-out clock is supplied to the phase discriminator via another frequency divider.  A succession of clocks shifted in phase relative to one another is provided by a generator from an auxiliary frequency of a crystal oscillator which feeds an auxiliary successor sequence clock generator which provides a plurality of successor auxiliary clocks.   Which of these clocks provides the read-out clock after a division in a frequency divider is defined by a switching frequency output by a frequency divider which is controlled by the phase discriminator.

Title: A process for making low optical density polymers and copolymers for photoresists and optical applications
Inventor: SHEEHAN MICHAEL T
IPC: C08F112/14
Filed: 1991-06-20
Abstract: The present invention pertains to a process for the preparation of polymers comprising poly(4-hydroxystyrene) or substituted poly(4-hydroxystyrene) or both. The polymers have low optical density (absorbance) over a wavelength range from about 240 to about 260 nm, as well as low optical density over the near UV and visible spectrum (310 to 800 nm). Such polymers arc produced by polymerizing 4-acetoxystyrene and/or substituted 4-aeetoxystyrene monomers, with or without other comonomers, and subsequently performing transesterification. In the most preferred embodiment of the present invention, the polymers are produced using at least one alcohol as a reaction medium, a chain transfer agent and a transesterification reactant, providing an unusually economic process. These polymers are particularly useful as photoresist components for use in combination with deep UV, X-ray, and E-Beam imaging systems.        To obtain polymers having low optical density over the 240 to 260 nm radiation wavelength range, it is necessary to use an initiator which does not comprise a substantially absorbant structure over the 240 to 260 nm range or to use an initiator concentration of less than about 3 mole % of the monomer(s), to obtain a polymerization conversion of the initial polymerization monomers of at least about 90% by weight, or to remove residual monomer(s) from the reaction medium prior to transesterification, and to obtain a transesterification conversion of the polymerized monomers of at least 85% by weight. It is also necessary to avoid the use of transesterification catalysts which can cause the formation of chemical structures which can absorb over the 240 to 260 nm radiation wavelength range.
