摘要： An electrostatic chuck for holding a wafer in a plasma processing chamber, the chuck including a pedestal having a top surface, an internal manifold for carrying a cooling gas, and a first plurality of holes leading from the internal manifold toward said top surface; and a dielectric layer on the top surface of the pedestal. The dielectric layer has a top side and second plurality of holes, each of which is aligned with a different one of the holes of the first plurality of holes in the pedestal. The first and second holes form a plurality of passages extending from the internal manifold to the top side of the dielectric layer and through which the cooling gas is supplied to the backside of the wafer. Each of the first holes and the second hole aligned therewith form a different one of the plurality of passages. The passages are concentrated in regions of the dielectric layer that are in proximity to regions of higher leakage of cooling gas when the wafer is held against the electrostatic chuck by an electrostatic force.

摘要： In a vehicle seat (car seat 1) including a first seat portion (seat cushion 10) movable between a use position and a retracted position, and a second seat portion (seat back 20) movable between a use position and a retracted position, an actuator mechanism is configured to cause the second seat portion to start moving toward its retracted position at a time when the first seat portion passes a predetermined intermediate position that is on a way from the use position toward the retracted position. In one embodiment, the actuator mechanism includes a biasing member (torsion spring 13, 23) configured to bias each of the seat cushion 10 and the seat back 20 from the use position toward the retracted position, a lock member (lock arm 42) configured to lock the seat back 20 in the use position, and an unlock device (cable 44, 42A) configured to release the lock member to cause the seat back 20 to start moving toward the retracted position, at a time when the seat cushion 10 passes the predetermined intermediate position that is on the way from a posture in which the seat cushion is ready for use toward a posture in which the seat cushion 10 is tipped up.
