    • Techniques for etching a wafer layer using multiple layers of the same photoresistant material and structures formed using such techniques are provided. In a method, first, multiple layers of the same photoresist material are formed over the wafer layer to form a composite photoresist layer. The composite photoresist layer is patterned and developed to form a patterned photoresist layer. Exposed portions of the wafer layer are then removed using the pattern photoresist layer. Each of the multiple layers of photoresist may, for example, be formed to a maximum rated thickness for the photoresist material. Structures formed using this process may have relatively small dimensions (e.g., widths of 5 microns or less or a spacing or pitch of 5 microns or less). In addition, structures may also have sidewalls which are relatively long, smooth, and/or vertical.
    • 提供了使用相同光致抗蚀剂材料的多层蚀刻晶片层的技术和使用这些技术形成的结构。 在一种方法中,首先在晶片层上形成多层相同的光致抗蚀剂材料以形成复合光致抗蚀剂层。 将复合光致抗蚀剂层图案化并显影以形成图案化的光致抗蚀剂层。 然后使用图案光致抗蚀剂层去除晶片层的暴露部分。 例如,可以将多层光致抗蚀剂中的每一层形成为光致抗蚀剂材料的最大额定厚度。 使用该方法形成的结构可以具有相对小的尺寸(例如,5微米或更小的宽度或5微米或更小的间距或间距)。 此外,结构还可以具有相对长,平滑和/或垂直的侧壁。

    • Using standard or “off the shelf” cable to interconnect between the PET block detector and the detector circuit may save substantial costs given the number of PMTs in a PET system. Given space constraints, simple maintenance with reduced risk of disturbing cabling is desired, making ongoing use of standard cabling without adding further cabling desired. To implement digital gain control, a further communication is provided between the PET detector block and the detector circuit. Since the standard cable may not have additional wires for such communications and to reduce timing degradation, the PMT signals are combined, such as generating position and energy signals at the PET detector block. The four PMT signals are reduced to three signals without reduction in function, allowing a fourth twisted pair of wires in a CAT5 cable to be used for digital gain control.
    • 使用标准或“现成”电缆在PET块检测器和检测器电路之间进行互连可以节省大量成本,因为PET系统中PMT的数量。 鉴于空间限制,需要简单的维护,减少干扰布线的风险,不断增加布线需求,不断使用标准布线。 为了实现数字增益控制,在PET检测器块和检测器电路之间提供进一步的通信。 由于标准电缆可能没有用于这种通信的附加电线并且减少定时劣化,所以组合PMT信号,例如在PET检测器块处产生位置和能量信号。 四个PMT信号减少到三个信号而不减少功能,允许CAT5电缆中的第四根双绞线用于数字增益控制。
