Abstract: Disclosed herein are a method and apparatus for silylation of positive or negative photosensitive resist layer on a semiconductor wafer after the resist layer has been exposed to radiant energy through a mask which includes introducing a silylating agent to the wafer at high pressure over 760 torr and, usually, at temperatures less than 180° C. Increased pressure increases the rate of silylation, allows practical use of lower process temperatures, and, therefore, allows better process control. The apparatus for applying the high pressure silylation process includes a process chamber having a port and a process gas inlet; a heated substrate in the process chamber; a loadlock in fluid communication with the process chamber through the port; and a gas generator in fluid communication with the process chamber through the gas inlet.

Abstract: According to an illustrative example of the invention, a gas spring comprises a cylinder (11) and a piston rod (12). The piston rod is axially movable with respect to the cylinder and has a fastening eye (13) mounted on the outer end of the piston rod. A tubular protection member (16) surrounds an end portion of the cylinder adjacent to the end of the cylinder which is passed by the piston rod. The other end of the protection tube surrounds a holding disk (15) fixed to the piston rod ad­jacent to the fastening eye. The protection tube and the piston rod define an air space (17) therebetween. The air space is substantially tight against a liquid treating agent, such as a lacquer. On the other hand, the air space is in air flow connection with the surrounding atmosphere so that in response to axial movement of the piston rod with respect to the cylinder, excessive pressure within the air space is prevented.
