摘要: The present invention generally provides methods and apparatuses that are adapted to form a high quality dielectric gate layer on a substrate. Embodiments contemplate a method wherein a metal plasma treatment process is used in lieu of a standard nitridization process to form a high dielectric constant layer on a substrate. Embodiments further contemplate an apparatus adapted to "implant" metal ions of relatively low energy in order to reduce ion bombardment damage to the gate dielectric layer, such as a silicon dioxide layer and to avoid incorporation of the metal atoms into the underlying silicon. In general, the process includes the steps of forming a high-k dielectric and then treating the deposited material to form a good interface between the gate electrode and the high-k dielectric material. Embodiments also provide a cluster tool that is adapted to form a high-k dielectric material, terminate the surface of the high-k dielectric material, perform desirable post treatment steps, and form a gate layers.

摘要: A method for forming an oxide layer pattern and a method for patterning a semiconductor device using the same are provided to improve the yield and characteristic of a semiconductor device by reducing particles and defects due to the particles. A patterning target layer and an oxide layer(102) are sequentially formed on a semiconductor substrate(100). Boron ions of 1.0X10^16 atm/cm^2 over are implanted into the oxide layer in a region on which an oxide layer pattern is to be formed. The oxide layer on which the boron ion implantation is not performed is wet-etched to form the oxide layer pattern. The patterning target layer is patterned by using the oxide layer pattern as a mask. The oxide layer pattern defines a forming region of an isolation layer trench(106) and the patterning target layer includes the semiconductor substrate. After the patterning target layer is patterned, the oxide layer pattern is removed.

摘要: A method of inhibiting degradation of a transistor gate oxide film by high density plasma is disclosed. After a gate electrode is formed, impurity is implanted on the surface of an oxide film, thereby changing surface characteristics of the oxide film to scatter ultraviolet rays which are factors of degradation of the gate insulating film. Accordingly, the ultraviolet rays are prevented from being permeated into a gate insulating oxide film.

摘要: PURPOSE: A fabrication process of a semiconductor device is provided to prevent a bottom film from being etched during wet etching of a top film, without forming an etching stopper layer in a step of forming a contact hole in a multilayered interlayer dielectrics. CONSTITUTION: According to a fabrication process of a semiconductor device, a HSQ(Hydrogen Silisesquioxane) film(4) is formed on a silicon oxide layer(1). And a region(5) where boron is introduced is formed by irradiating B2H6 plasma onto the HSQ film. After forming a plasma TEOS film(6) on the region, a concave part(8) is formed by a chemical solution containing HF, and then the wet etching is stopped on the region where boron is introduced. Then, a contact hole(9) reaching an Al wire(2) is formed by dry etching the HSQ film revealed at the bottom of the concave part. Then, a multilayered wire structure is formed by filling the contact hole with the top wire material.

摘要: PURPOSE: A method for fabricating a semiconductor device is provided to reduce a thickness of a photoresist layer and to realize a higher etch selectivity of the photoresist layer. CONSTITUTION: A fabricating process for a semiconductor device includes a step of forming a polysilicon layer(22) on a semiconductor substrate(20), a step of coating a photoresist layer on the polysilicon layer(22), a step of forming a photoresist pattern(28) from the photoresist layer, a step of curing the photoresist pattern(28), and etching the polysilicon layer(22) by employing the photoresist pattern(28) as an etch mask. In particular, the photoresist pattern(28) is carbonized before the curing step. The carbonization of the photoresist pattern(28) is carried out by an ion implantation process. Preferably, argon ion is implanted at a tilt angle. Since the carbonized photoresist pattern(28) has a higher etch resistance than ever, a thinner photoresist pattern is obtained.
