    • A method for manufacturing a semiconductor chip which has transistors is disclosed. The transistors include first type transistors which have a first type of doping and second type transistors which have a second type of doping different than the first type of doping. The method includes forming a conductive layer on a substrate. The conductive layer includes first regions that have the first type of doping and second regions have the second type of doping. The invention patterns a mask over the conductive layer, and the mask protects portions of the conductive layer where gate conductors will be located. Next, the invention partially etches unprotected portions of the conductive layer. The partially etching process allows a layer of the unprotected portions to remain, such that the substrate is not exposed by the partially etching process. The invention forms a passivating layer on exposed vertical surfaces of the conductive layer and completely etches unprotected portions of the conductive layer to expose the substrate. The invention then dopes exposed portions of the substrate to form source/drain regions.
    • 公开了一种制造具有晶体管的半导体芯片的方法。 晶体管包括具有第一类型掺杂的第一类型晶体管和具有不同于第一类型掺杂的第二类型掺杂的第二类型晶体管。 该方法包括在衬底上形成导电层。 导电层包括具有第一类型的掺杂的第一区域和第二区域具有第二类型的掺杂。 本发明在导电层上形成掩模,并且掩模保护导电层在栅极导体将被定位的部分。 接下来,本发明部分地蚀刻导电层的未受保护的部分。 部分蚀刻工艺允许保留未保护部分的层,使得基板不被部分蚀刻工艺暴露。 本发明在导电层的暴露的垂直表面上形成钝化层,并且完全蚀刻导电层的未受保护的部分以暴露衬底。 然后,本发明掺杂衬底的暴露部分以形成源极/漏极区域。

    • An improved standing valve which regulates the amount of accumulated fluid in the tubing string of an oil and gas well, to an amount that is within the purging capability of the gas-lift method. The present invention provides a hydrostatic standing valve with a floating valve seat which is displaced in response to the weight of an accumulated fluid head. A ball seals against the floating valve seat and floats with it, but the displacement of the ball is limited by a positive stop provided by a rod supported by the standing valve body. When the valve seat displaces beyond that of the ball, as limited by the positive stop, the ball is sealingly disengaged from the valve seat and fluid flows out of the tubing string. The dynamic response of the spring to the weight of the fluid head regulates the accumulated head to not exceed a predetermined amount so that the fluid head can be predicted and regulated below an amount that can be reliably purged by conventional gas-lift methodologies, either continuous or intermittent.
    • 一种改进的立式阀,其将油气井的油管柱中的累积流体的量调节到气举方法的清洗能力之内。 本发明提供一种具有浮动阀座的流体静压立式阀,该浮阀阀座响应于积聚的流体头的重量而移位。 球与浮动阀座密封并与其浮动,但球的位移受到由立式阀体支撑的杆提供的正向止挡的限制。 当阀座移动超过球的位置时,如正停止所限定,球与阀座密封地脱离,并且流体从管柱中流出。 弹簧对流体头的重量的动态响应将累积的头部调节到不超过预定量,使得可以将流体头预测和调节到低于可以通过常规气举方法可靠地清除的量,连续 或间歇性。

    • The present disclosure is directed toward a downhole tool used to free stuck tools in a wellbore and the method of using the downhole tool. The downhole tool includes at least one packer element for engaging a casing in a wellbore. The packer works to isolate one area of the casing from another. The downhole tool also includes at least one slip element for engaging the casing to maintain the position of the downhole tool in the casing or wellbore. Further, the downhole tool includes a mandrel slidably disposed within the at least one packer element and the at least one slip. The mandrel includes at least one port disposed therein above the at least one packer element when the mandrel is in a first position.
