Across 2. MEMS components that move mirrors or other MEMS devices are called Three or more colored output from the DMD array The acronym for digital light processing. are contained in the color wheel of a DLP system to provide a colored 5. 7. 8. After fabrication a DMD goes through a series of tests, most of which are electrical. The final test is a 10. To electrically 13. When a DMD mirror is not reflecting light it is said to be test a DMD array, the mirrors are turned ON and OFF for 2 to 24 hours inside a burn-in furnace strip is placed on DMD windows for the purpose of absorbing moisture. 14. A is to join two or more components together 0 coating that enhances the transmission of light is applied to the protective windows in a 18. An anti DMD 22. The tendency for surface forces to cause small structures to stick. 24. In MEMS fabrication a layer provides spacing between two or more components by first being deposited then removed. When a micromirror is reflecting light it is said to be 25. Down 1. 3. The component of a DMD micromirror that supports the mirror's support post. Small spring tips are constructed on the yoke of a DMD mirror to overcome micromirror to stay ON with voltage removed. The fabrication process used to remove the protective resist layer after the develop process step is called a lasma A microsystems device that integrates optical, mechanical and electrical The acronym for digital mirror device The material used to construct the post, hinge and yoke of a DMD micromirror In a DMD, one micromirror is one A The thin film used as a sacrificial layer that provides spacing and protection for the micromirrors. A(n) the tendency of a 4. 6. 7. 9. 11. 12. 15. 16. is applied to the electrode of a micromirror to turn the mirror ON is used to harden epoxy process uses UV light, heat and pressure to connect the windows of the DMD to the CMOS wafer In a DMD the hinge that is fabricated to overcome stiction is called the The fabrication process that removes unwanted material from a laver Hundreds and even thousands of micromirrors on a chip is called a(n) The fabricated channels that provide access to the CMOS circuitry 19. 20. 21. 23. hinge

Answer 1

2} Static random-access memory (SRAM)

Static random-access memory   :  is a type of semiconductor memory.

To move the mirrors, first loaded into an SRAM cell located at each pixel and connect it to the electrodes. Once all the SRAM cells have been loaded, the bias voltage is removed, allowing the charges from the SRAM cell to control, moving the mirror.

7) Digital Light Processing ------- DLP

set of chipsets based on optical micro-electro-mechanical technology that uses a digital micromirror device.

10 } aluminum micromirrors

DOWN :

6) a microsystem device that integrate the optical , mechanical and electrical ----  Micro-electromechanical systems (MEMS)

Micro-electromechanical systems (MEMS) is a process technology used to create tiny integrated devices or systems that combine mechanical and electrical components.

7) digital micromirror device ----- DMD

11)  micromirror

The DMD is an electro-mechanical element . there are 2 stable micromirror states (+12° and –12° for most current DMDs) that are purposeful by geometry and electrostatics of the pixel during operation.
