Patent CA-2144092-A1 (CA)
Inventor: ASPNES DAVID E
IPC: H01L21/205
Filed: 1993-08-20
Abstract: A method of an apparatus for extracting dielectric constants from ellipsometric data taken during the growth of a semiconductor thin film (10) and using the extracted dielectric constants to control the composition of the growing film by adjusting the growth conditions. An expression is used for the derivative of the pseudo-dielectric function with respect to the thickness of the thin film within a three-phase model, and the expression is exact to first order in thickness of the film. The expression is quadratic with respect to the dielectric function for a homogeneous thin film and additionally depends on the dielectric function of homogeneous substrate (12) underlying the thin film. Values of the measured pseudo-dielectric function are substituted for the dielectric function of the substrate, and the expression is then solved for the dielectric function of the thin film.

Patent CA-2149849-A1 (CA)
Title: Actuator
Inventor: HAYWARD VINCENT
IPC: F16F15/00
Filed: 1995-05-19
Abstract: An actuator develops a displacement from a force; the actuator employs active tension elements which comprise a fiber or fibers which shorten under activation, for example, shape memory alloy fibers; the fiber or fibers are entrained between opposed, spaced apart support members, typically a stack of spaced apart disks; the entrained fiber or fibers define a cage of crossing lengths of fiber in symmetrical array, typically a helicoidal array. Activation of the fibers shortens the fiber lengths producing a relative displacement of the support members which can be translated to a component which is to be displaced, and to which the actuator is operably connected, in another embodiment the active tension elements stretch under stress so that instead of an actuator there is formed a shock absorber which eliminates displacement with a force.
