Title: Formation of microstructures with removal of liquid by freezing and sublimation
Inventor: GUCKEL HENRY
IPC: H01L21/306
Filed: 1990-02-02
Granted: 1999-02-01
Abstract: Micromechanical structures having surfaces closely spaced from surfaces of a substrate are formed using normal wet etching techniques but are not dried in a conventional manner. While the substrate with the microstructures formed thereon is still wet, the substrate is covered with a liquid that can be frozen, such as deionized water. The liquid on the flooded structure is then frozen in a well controlled manner such that freezing is completed before the microstructure is uncovered. The microstructures are therefore undeflected and are covered by a solid on all surfaces. This solid is then sublimated at a predetermined temperature. Because the frozen liquid (e.g., ice) supports its own surface tension, the microstructures are not drawn toward the substrate, as occurs with the drying of liquids. The sublimation of all the frozen liquid leaves undeflected microstructures with no permanent bonding of the facing surfaces of the microstructure and the substrate.

Abstract: Discussed is a pellicle structure comprising a frame having a through opening, a pellicle film spread around the opening of the frame, the pellicle film having a coating layer formed at least on the inner surface thereof, and a bonding portion for bonding the frame to the periphery of the pellicle film through an adhesive layer, wherein there is no coating layer in the bonding portion (the coating having dissolved or dispersed in the adhesive) and the pellicle film is directly bonded to the frame by the adhesive. This pellicle structure is prepared by coating an adhesive, capable of dissolving the coating layer of the pellicle film around the opening of the frame, contacting the adhesive-coated surface of the frame with the surface of the coating layer of the pellicle film so as to dissolve and remove the coating layer in the bonding portion and curing the adhesive so that the pellicle film is directly bonded to the frame.
