The present invention is a method for producing a bonded wafer, comprising at least: bonding a base wafer serving as a support substrate to a bond wafer made of a silicon single crystal via an insulator film or directly bonding the wafers to provide a bonded wafer; and reducing a thickness of the bond wafer to form a thin film made of the silicon single crystal on the base wafer, wherein the thickness of the bonded wafer is reduced based on at least surface grinding while measuring the thickness of the bond wafer, and surface grinding with respect to the bond wafer is stopped when the thickness of the bond wafer reaches a target thickness. As a result, the method for producing a bonded wafer enabling a silicon single crystal thin film to precisely have a desired film thickness, a bonded wafer, and a surface grinding machine enabling a silicon single crystal thin film to precisely have a desired film thickness are provided.

The present invention provides a method for manufacturing a bonded wafer comprising steps of forming an oxide film on at least a surface of a base wafer or a surface of a bond wafer; bringing the base wafer and the bond wafer into close contact via the oxide film; subjecting these wafers to a heat treatment under an oxidizing atmosphere to bond the wafers together; grinding and removing the outer periphery of the bond wafer so that the outer periphery has a predetermined thickness; subsequently removing an unbonded portion of the outer periphery of the bond wafer by etching; and then thinning the bond wafer so that the bond wafer has a desired thickness, wherein the etching is conducted by using a mixed acid at 30° C. or less at least comprising hydrofluoric acid, nitric acid, and acetic acid. Thus there is provided a method for manufacturing a bonded wafer by which unbonded portions of the outer periphery of the bond wafer are removed with a high selectivity ratio (RSi/RSiO2) without causing metallic contamination.

In a legged mobile robot having a body and legs connected to the body, a seating aid is provided at its body so as to enable to sit on a seat. With this, the space occupied by the robot can be decreased to reduce space during storage and transport, and also enhance safety in the course of transport. In addition, maintenance work is simplified because immobilization in the seated condition is possible. Still further, the range of works is expanded to enable deskwork and the like. Further, the seating aid is provided at a location that is rearward of a center of gravity of the robot when the robot is seated. With this, the moment acting on the robot about the center of gravity during seating does not operate to tilt the robot rearward and, therefore, the robot can be enabled to keep a stable posture from before to after sitting down.

The legged mobile robot the foot comprises a foot main body connected to each leg, a toe provided at a fore end of the foot main body to be bendable with respect to the foot main body, and a bending angle holder capable of holding a bending angle of the toe in a bendable range of the toe. In addition, a legged mobile robot control system is configured to hold the bending angle of the toe at a first time point which is a liftoff time of the leg from a floor or earlier thereof, and to release the bending angle at a second time point after the leg has lifted off the floor to restore the toe to a initial position. With this, the bending angle at the time of liftoff can continue to be held after liftoff, whereby the robot can be prevented from becoming unstable owing to the toe contacting the floor immediately after liftoff. In addition, stability during tiptoe standing can be enhanced.
