20090109560 | POLYIMIDE DEFORMABLE MIRROR - This invention concerns the fabrication of deformable mirrors that can be used for adaptive optics applications to correct wavefront aberrations. The deformable mirror uses a polyimide substrate with a PZT layer, which is cut by laser to produce a structure with a free end attached to the polyimide substrate at one corner. The deformable mirror has an aperture less than 10 cm and is cost-effective to produce. The deformable mirror is driven piezoelectrically as a bimorph or monomorph and can achieve a stroke of 15 microns and a bandwidth of 1 kHz for less than 20 volts. The deformable mirror uses a continuous sheet, which is anchored at only one point, which corresponds to the point of arbitrary zero phase, and is free everywhere else to conform to the wavefront. This cannot be achieved with silicon micromachined mirrors, which are electrostatically actuated because surface micromachining produces delicate films which must be anchored periodically for support. | 04-30-2009 |
20090219541 | Lensless imaging with reduced aperture - An image of an object can be synthesized either from the Fourier components of the electric field or from the Fourier components of the intensity distribution. Imaging with a lens is equivalent to assembling the Fourier components of the electric field in the image plane. This invention provides a method and a means for lensless imaging by assembling the Fourier components of the intensity distribution and combining them to form the image with the use of amplitude splitting interferometer. The angular spectrum of the electromagnetic radiation consists of wavefronts propagating at different angles. The amplitude of each wavefront is split and interfered with itself to create sinusoidal fringe patterns having different spatial frequencies. The sinusoidal fringe patterns are combined to form an image of the object. This method applies to. coherent and incoherent light. | 09-03-2009 |
20100035052 | Polyimide substrate bonded to other substrate - Polyimide substrates are bonded to germanium wafers having an epitaxially grown III-V layer and a metal layer. The polyimide substrate and the Ge wafer are subsequently thinned by grinding and etching to reach a final thickness of 25 μms Ge on 25 μms adhesive layer on 50 μms polyimide substrate. The choice of adhesive is of paramount importance. There are several requirements for the adhesive layer to act as a permanent carrier of the thin fragile multijunction solar cell. The adhesive must remain flexible after curing and have a low CTE. It is desired to use an adhesive that cures without the addition of heat, preferably at room temperature. Furthermore, the adhesive layer should have a uniform thickness preferably less than 25 μms (1 mil) and be void-free. It is desired to use a clear adhesive which does not contain any particles in order to obtain a smooth uniform void-free bondline. However, clear adhesives have CTE's that are larger than 80 ppm/° C. and which can be as high as 200 ppm/° C. or more above the glass transition temperature. This is especially problematic for hard adhesives. The ideal adhesive is applied at room temperature but must withstand up to 250° C. during post-bond metallization of the front side of the solar cell. Another important parameter, which affects the ability to spread a liquid adhesive over a 4″ area is the viscosity. Some adhesives, like paste, may have favorable properties but are too thick to spread evenly over a 4″ wafer. Ideally the adhesive is applied either by spinning or spraying. These represent a set of conflicting requirements. There is not one adhesive that has all the desired properties. A thin bonded wafer is demonstrated which has an epi-layer and a metal layer. | 02-11-2010 |

20150258769 | Rapid Thinning of GaN and SiC Substrates and Dry Epitaxial Lift-off - An epitaxially grown layer III-V solar cell is separated from the growth substrate by propagating a crack close to the epi/wafer interface. The crack is driven by the elastic strain energy built up due to thermal stresses between GaAs and polyimide by cooling below room temperature. A GaAs wafer is bonded to a polyimide substrate on the epi-side and scribed on the opposite side. The crack is initiated from the scratch and guided along the interface using an epitaxially grown sacrificial layer with lower fracture toughness under the solar cell. No expensive ion implantation or lateral chemical etching of a sacrificial layer is needed. The active layer is transferred wafer-scale to inexpensive, flexible, organic substrate. The process allows re-using of the wafer to grow new cells, resulting in savings in raw materials and grinding and etching costs amounting to up to 30% of the cost of the cell. Several cells are integrated on a common blanket polyimide sheet and interconnected by copper plating. The blanket is covered with a transparent spray-on polyimide that replaces the cover glass. The solar cell is stress-balanced to remain flat on orbit. | 09-17-2015 |
