摘要： A wafer-level manufacturing method produces stress compensated x-y gimbaled comb-driven MEMS mirror arrays using two SOI wafers and a single carrier wafer. MEMS structures such as comb drives, springs, and optical surfaces are formed by processing front substrate layer surfaces of the SOI wafers, bonding together the processed surfaces, and removing the unprocessed SOI layers to expose second surfaces of the front substrate layers for further wafer-level processing. The bonded SOI wafers are mounted to a surface of the carrier wafer that has been separately processed. Processing wafer surfaces may include formation of a stress compensation layer to counteract physical effects of MEMS mirrors. The method may form multi-layered conductive spring structures for the mirrors, each spring having a first conducting layer for energizing a comb drive, a second conducting layer imparting a restoring force, and an insulating layer between the first and second conducting layers.

摘要： A vapor cell includes an interrogation cell in a substrate, the interrogation cell having an entrance window and an exit window, and a first transparent thin-film heater in thermal communication with the entrance window. The transparent thin-film heater has a first layer in communication with a first pole contact at a proximal end of the heater and a layer coupler contact at a distal end, a second layer in communication with a second pole contact at the proximal end, and the second layer electrically coupled to the layer coupler contact at the distal end. An insulating layer is sandwiched between the first and second layers. The insulating layer has an opening at the distal end to admit the layer coupler contact and to insulate the remainder of the second layer from the first layer. The first and second pole contacts are available to complete an electric circuit at the proximal end, with magnetic fields for each of the first and second layers oriented in opposing directions when a current is applied through the circuit.

摘要： Micromachine fluidic apparatus incorporates a free-standing tube section and electrodes to actuate or control the movement of the tube section, or to sense the movement of the tube section, or both. Electronic circuitry, which may be disposed on the same substrate as the fluidic portion of the apparatus, is used in conjunction with the tube and electrodes in conjunction with a variety of different applications, including fluid flow measurement, fluid density measurement, fluid viscosity measurement, fluid transport, separation and/or mixing. According to a particular embodiment, the free-standing section of the tube is resonated for fluid flow and density measurements according to the Coriolis effect. Capacitive/electrostatic actuation techniques are used to control or resonate the free-standing section of the tube, and to detect variations in tube movement. Different methods of fabricating micromachine fluidic apparatus are also disclosed, including the use of fusion bonding of non-conducting substrates, high-aspect ratio etching techniques, and anisotropic etching and refill techniques, preferably utilizing chevron-shaped slit openings to fabricate microtube sections.

摘要： Provided is a chip-scale atomic clock having a folded optic configuration or physics package. In particular, the physics package includes a vapor cell for containing gaseous alkali atoms and a VCSEL for generating a laser light. One or more heating elements are positioned to simultaneously heat both the vapor cell and VCSEL to the required operating temperature. A micro-lens element, positioned between the VCSEL and a reflector, is used to first expand the beam of light, and then to subsequently collimate the light after it is once reflected. Collimated, reflected light passes through the vapor cell wherein the alkali atoms are excited and a percentage of the reflected light is absorbed. A detector, located opposite the reflector and micro-lens array, detects light passing through the cell. An error signal is generated and the output voltage of a local voltage oscillator is successively stabilized.
