Abstract:
To provide a method of manufacturing a semiconductor device in which the space between semiconductor films transferred at plural locations is narrowed. A first bonding substrate having first projections is attached to a base substrate. Then, the first bonding substrate is separated at the first projections so that first semiconductor films are formed over the base substrate. Next, a second bonding substrate having second projections is attached to the base substrate so that the second projections are placed in regions different from regions where the first semiconductor films are formed. Subsequently, the second bonding substrate is separated at the second projections so that second semiconductor films are formed over the base substrate. In the second bonding substrate, the width of each second projection in a direction (a depth direction) perpendicular to the second bonding substrate is larger than the film thickness of each first semiconductor film formed first.
Abstract:
A method for manufacturing a semiconductor device makes it possible to efficiently polish with a polishing tape a peripheral portion of a silicon substrate under polishing conditions particularly suited for a deposited film and for silicon underlying the deposited film. The method includes: pressing a first polishing tape against a peripheral portion of a device substrate having a deposited film on a silicon surface while rotating the device substrate at a first rotational speed, thereby removing the deposited film lying in the peripheral portion of the device substrate and exposing the underlying silicon; and pressing a second polishing tape against the exposed silicon lying in the peripheral portion of the device substrate while rotating the device substrate at a second rotational speed, thereby polishing the silicon to a predetermined depth.

A printhead includes a moveable membrane, a piezoelectric actuator to move the membrane, and electronic circuitry disposed on the moveable membrane. A method of fabricating a printhead includes fabricating CMOS circuitry on a first side of a circuit wafer, and forming a chamber in a second side of the circuit wafer such that a bottom of the chamber forms a moveable membrane and the CMOS circuitry is disposed on the moveable membrane opposite the bottom of the chamber. A printing system includes a printhead having CMOS circuitry formed on a first side of a moveable membrane, a chamber having a bottom comprising a second side of the moveable membrane, and a piezoelectric actuator formed over the CMOS circuitry, configured to cause displacement of the moveable membrane into the chamber.
