Patent number: 6020215Abstract: A microstructure comprising a substrate (1), a patterned structure (beam member) (2) suspended over the substrate (1) with an air-space (4) therebetween and supporting structure (3) for suspending the patterned structure (2) over the substrate (1). The microstructure is prepared by using a sacrificial layer (7) which is removed to form the space between the substrate (1) and the patterned structure (2) adhered to the sacrificial layer. In the case of using resin as the material of the sacrificial layer, the sacrificial layer can be removed without causing sticking, and an electrode can be provided on the patterned structure. The microstructure can have application as electrostatic actuator, etc., depending on choice of shape and composition.Type: GrantFiled: April 28, 1997Date of Patent: February 1, 2000Assignee: Canon Kabushiki KaishaInventors: Takayuki Yagi, Masatake Akaike

Patent number: 5861603Abstract: A method of manufacturing a mask in which laser radiation is projected to a mask substrate of silicon and a supporting frame of heat resisting glass, while a voltage of about 1000-10000 V is applied between the mask substrate and the supporting frame. Cooling water is caused to flow to suppress temperature rise due to the irradiation, to maintain the mask substrate and the supporting frame at a predetermined normal temperature (about the mask temperature in a lithographic pattern transfer process). The light projecting step is performed for a period not shorter than 10 minutes whereby anodic bonding of the mask substrate with the supporting frame is achieved. This prevents a shift of the mask pattern and/or deformation of the mask substrate, and it assures the manufacture of a high precision mask.Type: GrantFiled: June 27, 1997Date of Patent: January 19, 1999Assignee: Canon Kabushiki KaishaInventors: Takeshi Miyachi, Hiroshi Maehara, Masatake Akaike
