Description of the Invention: [Technical Field] The present invention relates to a process for forming a gate in an integrated circuit package circuit device. [Prior Art] For the towel, the current situation is _ no _ increase the density of the device. Degree, continuous efforts to shrink the semiconductor level on the semiconductor wafer. In order to achieve such a high package density, small feature sizes are required. This includes the interconnect width and spacing as well as the surface geometry of the edges and corners of different features such as 疋. This is achieved by creating features with tiny spacings adjacent to each other. , whispering, including the technique used to make the integrated circuit, in which the sense f (herein referred to as photoresist) will be traversed by the coated surface (eg optical light, x-ray or Under the electron beam), 1 but this i image is imaged by the ^Bugan/, suitable for receiving-to-convert pattern. Once again, the eight will be formed on the coated material without being erased. Through the mask ===, the imaged area can be more or less dissolved in the second special = in the age of throwing (4) soluble _ domain removal pattern imaging of the polymer that is more difficult to dissolve in the soil cloth. The same is the right or negative image of the job. There have been two kinds of failures over the years = two: ΐ: positive and negative photoresist. Using a positive photoresist, exposure to light, = two-shot, * using a negative photoresist, the exposure is not exposed to the knife, and the time is removed. Historically, negative photoresists have not been able to be used in line widths and 201201256 to be less than 3 microns. Therefore, the negative photoresist is used in the process of a very large integrated circuit (vLSI) device. The first problem is that the solid-state problem that can be used to make a sudden impact can have a fatal shadow mechanism on the integrated circuit. Many known layer materials have a faster::The mechanism of the concave profile in the upper layer of the layer is an oxidation effect. The other two sides of the stack are in addition to the base profile. There are other "this machine is much faster" which results in a recessed sidewall wheel which is well known for single layer specificity, and _effect 'derivative rr rate difference' Generally, δ, the helium doping concentration class, its _ rate is faster. Example 2: =:==rr Produces the derivative ===== This problem causes a short circuit of the conductive structures separated from each other. The size of the TM nanosphere becomes very difficult, a 5 201201256 [Explanation] The invention discloses a semiconductor farm and a manufacturing method thereof.

Finally, in some embodiments, the gate structure is polycrystalline In this case, the red/milk treatment includes oxygen flow in the range of 0 to 200 SCCM.

The oxidized stone on the surface of the spar sluice gate, and then a polycrystalline stone, the engraved (ME), followed by the first polycrystalline fineness (〇E), and finally the second polycrystalline bismuth overetching The process of (0E) is manufactured from Structure 2〇〇. This oxygen/argon treatment can be carried out in a single step comprising an argon ion county structure H0 and an exposed structure in oxygen. In this oxygen/argon treatment, oxygen provides a polycrystalline ruthenium residue and an oxidative removal process of the etched polymer. In the embodiment where the gate is a polysilicon, the simultaneous oxygen/argon treatment is preferably performed before the second polysilicon overetch (〇), and the flow rate of the argon can be applied to 1〇. Between the standard cubic meters per minute (SCCM) range, the oxygen flow rate can be between 0 and 200 SCCM. In addition, the source dissociation molecular enthalpy of this process can be used between 10 and 1000 watts, and the bias energy of this process can be used between 10 and 300 watts. In an alternate embodiment, the simultaneous oxygen/chlorine treatment, 201201256, may also be performed prior to the first polylithic excess (0E) or prior to (WSix) excessive #〇 (〇£). In the embodiment where the gate is a metal gate (e.g., a crane), the argon flow rate can be applied between 〇 to 1000 SCCM and between 0 and 200 SCCM. In addition, the source of this process can dissociate L molecules from 1 〇 to 1000 watts, which is between 10 and 300 watts. >=* In the alternative embodiment, the structure 220 can be carried out by including - Wei He (W (four) main meal (ME), followed by a stone Xihua crane (absolute gamma remnant (〇e), another one After the polycrystalline stone (4) _), then the real money is emptied into the oxygen/argon 13 , and then the first and the second is - the second polycrystalline material is etched into the private, and is manufactured in the structure 200. In the example, the oxygen/argon treatment may be an oxygen/argon treatment using oxygen dioxide in the oxidation, and between the argon SCCM ranges, the oxygen flow rate may be used between 0 7 27H and the dry circumference. In addition, the source of the process The polar dissociation molecular energy is best between ^ = G watt range, and the (4) 1 bias can be used between 2MHz and 10 to 2 watts. It can be _ the above method is closed or asynchronous However, the failure of the bridge is not severely affected by the critical dimension and profile of the gate. This oxygen/argon treatment can also lower the height of the oxide layer. The gate structure 220 & A set of bottle-shaped character line structures 222 and 224. The first I-frame structure 222*224 has at least some bottle-like profile including the first, =W1 , W2 and W3. The first and third widths W1 and W3 = or a width of substantially _. However, the second MW is two and M4' and larger than the third width W3. Therefore, the word line structure 222 ': Included from the side of a wafer (the wafer shown in Figure 2 is below the layer 11 201201256 102 =), the _width, the second width is higher than the first width, and the second width is the first The width J'-the third width is higher than the second width, and the third width is smaller than the second width. More specifically, each of the word line structures 222 and 224 may include the first crystal layers 1〇4 and 1〇6. 'Where the first polysilicon layer ι〇4 is from the wafer side up k = the first crystallization layer 1 〇 6 is narrowed from the wafer side upward. For example, in this example, the second H is 'first The polycrystalline stone layer has just widened from the first width wi to the second width two 2' and the second cherished stone layer 1〇6 has been narrowed from the second width number to the third width milk. The widest part of the width W2 is not fixed at the interface between the HM and the second polycrystalline layer, and can also be moved up or down while in the first-polycrystalline layer 1〇4 Medium or second polycrystalline dream The line structure 222 and 224 of the column can effectively increase the polycrystalline stone sluice gate _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ The use of ¥ = of word line structures 222 and 224 can reduce the barrier spread as described above.
