摘要:
A method for forming indicia on a semiconductor device package, such as laser marked or ink stamp marked indicia. The method can be performed on an apparatus, such as a production apparatus, which forms the indicia as well as performs semiconductor device trim and form operations. An embodiment of the present teachings ensures that the indicia marking process at a laser marking station does not occur simultaneously with the device trim and form operations at a trim and form station. Trim and form operations, particularly using a ram press, can impose vibrations on the laser marking station. Ensuring that laser marking does not occur simultaneously with trim and form operations removes the negative effects of vibration on the laser marking station.

A method of transforming a serial scrambler to a parallel scrambler, a parallel scrambler and a double-edge-triggered register with XOR operation are provided. The method transforms a serial scrambler to a parallel scrambler according to a characteristic polynomial: P ( x ) = ∑ q = 0 N c q x q or b ( i ) = ∑ q = 1 N c q b ( i - q ) . The method first determines a transformation formula: b ( kN + i ) = ∑ q = 1 N c q b ( ( k - R ) N + i + R ( N - q ) ) according to the parameters of the characteristic polynomial. The parallel bits Bj=[bMj, bMj+1, . . . , bMj+M−2, bMj+M−1] are arranged in order. The transformation number R=2t (the initial number of t is 0) is set. The parallel bits are replaced by the transformation formula. When (k−R)N+i+R(N−q) is larger than Mj−1 in the transformation formula, 1 is added to t in the transformation formula R=2t and the transformation formula is re-counted. Finally, the XOR gates are connected to the registers according to a computed result from the transformation formula.

摘要:
A resistor layout and method of forming the resistor are described which achieves improved resistor characteristics, such as resistor stability and voltage coefficient of resistance. A resistor is formed from a conducting material such as doped silicon or polysilicon. The resistor has a rectangular first resistor element, a second resistor element, a third resistor element, a fourth resistor element, and a fifth resistor element. A layer of protective dielectric is then formed over the first, second, and third resistor elements leaving the fourth and fifth resistor elements exposed. The conducting material in the exposed fourth and fifth resistor elements is then changed to a silicide, such as titanium silicide or cobalt silicide, using a silicidation process. The higher conductivity silicide forms low resistance contacts between the second and fourth resistor elements and between the third and fifth resistor elements. The second and third resistor elements are wider than the first resistor element and provide a low resistance contacts to the first resistor element, which is the main resistor element. This provides low voltage coefficient of resistance thermal process stability for the resistor.

A regeneration membrane is provided for dentistry. The traditional thin collagen is turned into a flowable and shapeable collagen gel. A photo-crosslinking agent (i.e. riboflavin (vitamin B2)) is added in a biomedical-level collagen gel to obtain the shapeable collagen gel. The shapeable collagen gel is filled in a pre-filled syringe. The shapeable collagen gel is squeezed to a destined position for paving and shaping. Then, crosslinking is processed through UV illumination for curing. Flowability is achieved for applying. After applying, solidification is finished through illumination to turn liquid into solid. Thus, a regeneration membrane is formed with biological tolerance.

摘要:
A novel method for enhancing interface adhesion between adjacent dielectric layers, particularly between an etch stop layer and an overlying dielectric layer having a low dielectric constant (k) in the formation of metal interconnects during the fabrication of integrated circuits on semiconductor wafer substrates. The method may include providing a substrate, providing an etch stop layer on the substrate, providing an oxygen-rich dielectric pre-layer on the etch stop layer and providing a major dielectric layer on the oxygen-rich dielectric pre-layer. Metal interconnects are then formed in the dielectric layers. The oxygen-rich dielectric pre-layer between the etch stop layer and the upper dielectric layer prevents or minimizes peeling and cracking of the layers induced by stresses that are caused by chemical mechanical planarization of metal layers and/or chip packaging.
