  • Patent number: 7785912
    Abstract: A piezo-TFT cantilever microelectromechanical system (MEMS) and associated fabrication processes are provided. The method comprises: providing a substrate, such as glass for example; forming thin-films overlying the substrate; forming a thin-film cantilever beam; and simultaneously forming a TFT within the cantilever beam. The TFT is can be formed least partially overlying a cantilever beam top surface, at least partially overlying a cantilever beam bottom surface, or embedded within the cantilever beam. In one example, forming thin-films on the substrate includes: selectively forming a first layer with a first stress level; selectively forming a first active Si region overlying the first layer; and selectively forming a second layer overlying the first layer with a second stress level. The thin-film cantilever beam is formed from the first and second layers, while the TFT source/drain (S/D) and channel regions are formed from the first active Si region.

  • Patent number: 7786965
    Abstract: One picture element of a liquid crystal panel is divided into a region I where a cell gap is set to 4 ?m and a region II where a transparent insulating film is formed and a cell gap is set to 2 ?m. In the region I, there occurs a phenomenon (overshoot) that, when a voltage is applied, luminance becomes high immediately before an alignment of liquid crystal molecules becomes stable, and in the region II, no overshoot occurs. Response characteristics of an entire picture element are those obtained by synthesizing the response characteristics in these regions. Parameters such as an area ratio of the regions I and II, and cell gaps are set so that a maximum luminance value is not greater than 110% of the luminance at a stable time.

    Abstract: A thin-film transistor (TFT) with a multilayer gate insulator is provided, along with a method for forming the same. The method comprises: forming a channel, first source/drain (S/D) region, and a second S/D region in a Silicon (Si) active layer; using a high-density plasma (HDP) source, growing a first layer of Silicon oxide (SiOx) from the Si active layer, to a first thickness, where x is less than, or equal to 2; depositing a second layer of SiOx having a second thickness, greater than the first thickness, overlying the first layer of SiOx; using the HDP source, additionally oxidizing the second layer of SiOx, wherein the first and second SiOx layers form a gate insulator; and, forming a gate electrode adjacent the gate insulator. In one aspect, the second Si oxide layer is deposited using a plasma-enhanced chemical vapor deposition (PECVD) process with tetraethylorthosilicate (TEOS) precursors.

  • Patent number: 7786959
    Abstract: When the transistor Q3 is OFF, a predetermined potential is supplied to a potential wire Ui such that a switching transistor Q2 becomes ON. This changes a gate potential of a driving transistor Q1 from an ON potential to a threshold potential. Thereafter, the transistor Q2 is turned OFF, with the result that the potential of the potential wire Ui is changed (in cases where the transistor Q1 is a p-type transistor, the potential is decreased). With this, the transistor Q1 allows a current to constantly flows therethrough, irrespective of the threshold potential. This shortens time for setting an output current of the driving TFT for driving a current driving type display element.

  • Patent number: 7787155
    Abstract: In a communications device, a terminal machine transmits/receives data over a network and makes a request for a response to a data transmission from a receiving-end machine. In the terminal machine, an e-mail message identifying unit determines whether data to be received over the network is response data to the response request, and a main control unit controls so as to preferentially receive data identified as the response data by the e-mail message identifying unit over other data. Thus, if an e-mail message is transmitted with a request for a disposition verification, a reply message to the disposition verification request can be quickly received from the receiving-end machine.

  • Publication number: 20100214498
    Abstract: In a discharge tube, a conductive ferrule is provided on an end portion of a glass tube. The ferrule includes a body that is to be mounted to the outer circumference of the glass tube and has a contact portion to be electrically conductively fixed to a relay connector (or a bearing device). Further included is a conductive portion that extends from the body so as to have elastic contact with an outer lead. The outer lead will not be under load due to the weight of the discharge tube, but the conductive portion solely has elastic contact therewith. Thus, stress concentration on the outer lead can be prevented.

  • Publication number: 20100212832
    Abstract: The present invention provides a stage device which does not generate the difference in level between an upper end of a lift pin and a setting surface of a stage in a state where a substrate to be treated is set on the setting surface of the stage, and provides a plasma treatment apparatus which suppresses the occurrence of uneven treatment by using the stage device as an electrode stage. At the center of an electrode stage (2), a spring type lift pin (20) having elasticity in a direction where the pin moves is provided. When the spring type lift pin (20) is at a storage position, a pin upper end (20a) of the spring type lift pin (20) protrudes above the setting surface (11) of the electrode stage (2). When the substrate (4) to be treated is set and adsorbed on the setting surface (11), the upper end of the lift pin is pressed down to the position that is at the same level as that of the setting surface (11) by a load applied by the substrate (4).
