摘要:
A flash memory including a substrate having a recess, a buried bit line, a word line, a single side insulating layer, a floating gate, a tunneling dielectric layer, a control gate, and an inter-gate dielectric layer is provided. The buried bit line extends below the recess of the substrate along a first direction. The word line is on the substrate, and extends above the recess along a second direction. The single side insulating layer is on a first sidewall of the recess. The floating gate is on a second sidewall of the recess to be opposite to the single side insulating layer. The tunneling dielectric layer is sandwiched by the floating gate and the substrate to contact the buried bit line. The control gate fills the recess and contacts the word line. The inter-gate dielectric layer is sandwiched by the control gate and the floating gate.

A dynamic random access memory (DRAM) structure has a stacked capacitor disposed above an upper source/drain region of a vertical transistor having a surrounding gate. The gates of each row of a memory array are electrically connected with a buried word line. Each of bit lines is disposed between two adjacent columns of transistors and electrically connected with lower source/drain regions through bit line contacts. The DRAM structure may have a unit cell size of 4F2.

An antivibration uniform-strength connector including two mating connection plates and a bolt. The connection plates are made of steel material having tensile strength proximate to that of steel reinforcements. The connection plates are made in accordance with the specifications of the steel reinforcements. Each connection plate has a central hole and two lateral extension sections. Each extension section has an opposite contact face. Contact recesses are formed on the contact faces and spaced from the central hole by equal or unequal distances. With steel reinforcements respectively held in the contact recesses, the bolt is tightened in the central hole of one connection plate to fasten the connection plates and fix the steel reinforcements in a double-cross or parallel pattern. The antivibration uniform-strength connector is applicable to the major steel reinforcements of a beam, a column, a bridge, a bridgeboard, etc. to truly strongly fixedly combine the steel reinforcements into a reinforcement network or reinforcement cage. Accordingly, the reinforcement network or reinforcement cage can bear much greater stress, especially the dynamic cyclic shear strength. Therefore, the antivibration strength of a building can be highly enhanced.
