A surgical stapling and severing instrument particularly suited to endoscopic procedures incorporates a handle that produces separate closing and firing motions to actuate an end effector. In particular, the handle produces multiple firing strokes in order to reduce the required amount of force required to fire (i.e., staple and sever) the end effector. A linked transmission reduces the required handle longitudinal length, yet achieves a rigid, strong configuration when straightened for firing. A traction biased firing mechanism avoids binding in driving this straightened linked rack in cooperation with an anti-backup mechanism, with a lockout mechanism that prevents releasing the closure trigger during firing. Furthermore, an external indicator gives feedback to the surgeon as to how far firing has progressed, as well as providing a manual retraction capability.

Disclosed herein is a method of cleaning oxide from a surface in the fabrication of an integrated device using reducing radicals and UV radiation. For silicon surfaces, the cleaning may be performed at a temperature at which a hydrogen-terminated passivated surface is stable, such that the surface remains protected after loading into the chamber until the cleaning is performed. Performing the cleaning at a lower temperature also consumes a reduced portion of the thermal budget of a semiconductor device. Epitaxial deposition can then be performed over the cleaned surface.
