How to improve the production yield of memory modules has always been one of the topics that memory module manufacturers are constantly pursuing. As a general rule, a memory module usually includes a memory cell area and a peripheral circuit area located at the periphery of the memory cell area. Wherein, the peripheral circuit area has a plurality of branch building members and a plurality of electrical connecting ports spaced apart by the supporting members, and the memory unit region can be connected to the other electronic devices through the m-connecting wires. In the body module, the height of the support is usually only slightly higher than the height of the miscellaneous connection (four). Therefore, when the memory module is transported by the conveyor belt (C_yer), the electrical connection pad may be easily conveyed by the conveyor belt or the roller (5) (8) because of the insufficient degree of the support member, and the memory is n' The solder resist layer formed on the substrate serves as a support member, and the space between the electrical connection pads is extremely narrow. Therefore, the current support (rigid (10) sleeve) is easier to achieve, and the thickness of the anti-glare layer is increased. The method is to increase the height of the support member, and the above-mentioned problem is solved by the invention. The present invention provides a method for manufacturing a peripheral circuit region of a memory module, and the height of the support member is obvious. Higher than the height of the electrical connection pad. The present invention provides a peripheral circuit area structure of a memory module, comprising a substrate, a plurality of electrical connection pads, and a plurality of teeth on the interdigitated (four) substrate. Each of the support members includes a layer of -_ and a layer, wherein the spacer is disposed on the substrate to cover the spacer in the layer of lightning, so that the height of the branch member protruding from the surface of the substrate is higher than the height of the surface of the substrate. The rigidity of the object is greater than the rigidity of the solder resist layer. The invention further provides a peripheral circuit of the memory module and a anti-fresh layer. The patterned metal layer is disposed on the substrate with two electrical connections and a plurality of metal spaces 2 interlaced with the electrical connections. The solder mask covers the metal spacers to form a plurality of support members, so that the support = convex is higher than the height of the new connection pad protruding from the surface of the new connection pad. (4) a method of structure, the package firstly forming a patterned metal layer on a substrate, wherein the patterned gold electrical connections and the complex numbers of the electrical connections are arranged in a staggered manner: a layer of glazing, wherein the anti-frying layer covers the readings of the four (4) fields, and the m-connecting pads are exposed, so that the height of the surface of the substrate is higher than the electrical connection and protrudes from the surface of the substrate. South degree. In the embodiment of the month, the above-mentioned spacers are arranged in a straight line by two electrical connections between the plurality of protrusions, and the height of the protrusions from the surface of the board is substantially equal to the electrical connection. The height of the surface of the substrate. Among them, these protrusions may be metal protrusions. In the embodiment of the present invention, the peripheral circuit area structure of the above memory module further includes a metal coating covering the new connection pads. Its towel, metal Lai domain money film. In order to make the present invention more detailed, the following is a detailed description of the following embodiments, together with the accompanying drawings. [Embodiment] FIG. 1 is a schematic view showing the structure of a seed card module in the present invention. Figure 2 is a cross-sectional view taken along line A-A of Figure 1. Please refer to FIG. 1 first. In this embodiment, the memory module 1GG may be a secret random access memory, a flash memory, or another memory weight group, which may have a memory unit leg and be located in the memory.

The memory cell region 1a may include a plurality of memory cells, such as a tunnel oxide layer, a floating gate (fl(10) gate), a dielectric layer, and a control gate. (strcedi gate) A stacked gate strueture. The detailed structure in the memory cell region 100a is omitted in Fig. 1 for simplification of the illustration. Next, referring to FIG. 1 and FIG. 2, the structure in the peripheral circuit area 10b includes a substrate 11A, a plurality of electrical connection pads 12A, and a plurality of support members 13A, wherein the electrical connection pads 120 The memory unit is electrically connected to the memory unit 1a and is arranged on the substrate in a staggered manner with the support member 130. That is to say, the memory unit in the memory unit area 100a can be electrically connected to other electronic devices (not shown) through the electrical contact 12G from the reading unit (10). Moreover, each support member 130 includes a spacer 132 and a solder resist layer 134, wherein the spacer 132 is disposed on the substrate 11 , and the solder resist layer 134 covers the spacer 132 to protrude the support 13 The height of the surface of the substrate 110 may be significantly higher than the height of the electrical connection pads 120 protruding from the surface of the substrate 110. As a result, the phenomenon that the memory module is scratched by the conveyor belt or the roller in the prior art can be improved. It should be noted that, in this embodiment, since the rigidity of the spacer 132 is greater than the rigidity of the solder resist layer 134, the overall twist of the branch member 130 is increased to be significantly higher than that of the electrical connection pad 120. 130 is less prone to
