Patent number: 7342607Abstract: A mathematical calculation method for an image-capturing device includes steps: estimating a green value of a red, blue pixel; calculating four differences between an estimated red value and four neighboring green pixels, weighing proportions of the four neighboring green pixels, and summing up the differences between the four products induced by multiplying the four differences and the four proportions respectively, as a green value G3? in the red pixel. A green value of a blue pixel will be obtained by mentioned steps. A blue value of the red pixel occurs when the following steps: figuring out differences between four green values and four blue values of four neighboring blue pixels, averaging the four differences, and subtracting the average of the four differences from the green value of the red pixel. A red value of the blue pixel and a red, blue value of the green pixel can be estimated, too.Type: GrantFiled: December 7, 2004Date of Patent: March 11, 2008Assignee: Service & Quality Technology Co., Ltd.Inventor: Wen-Jun Liu

Patent number: 6461969Abstract: A method for dry plasma selective etching of a pattern in a silicon nitride dielectric layer formed over a semiconductor substrate employed within a microelectronics fabrication. There is provided a semiconductor substrate having formed thereupon a pad oxide layer over which is formed a silicon nitride dielectric layer. There is formed over the substrate a patterned photoresist etch mask layer. There is then selectively etched the pattern of the photoresist etch mask layer into the silicon nitride layer employing a four-step etching process with three plasma etching environments which include; (1) a “break-through” etching step; (2) a “bulk” etching step to remove a majority of the silicon nitride layer and a “buffer” etching step to remove the remainder of the silicon nitride layer; and (3) an “over-etch” step to complete removal of silicon nitride without excessive etching of underlying material.Type: GrantFiled: November 22, 1999Date of Patent: October 8, 2002Assignee: Chartered Semiconductor Manufacturing Ltd.Inventors: Pei Ching Lee, Wen Jun Liu, Mei Sheng Zhou

Patent number: 6271115Abstract: An improved method for removing a photoresist mask from an etched aluminum pattern after etching the pattern in a chlorine containing plasma has been developed. The method is a five step process, in which the first step is in a microwave generated plasma containing O2 and H2O; the second step is in a microwave generated plasma containing O2 and N2; the third step is in a microwave generated plasma containing H2O; the fourth step is in a microwave generated plasma containing O2 and N2; and the fifth step is in a microwave generated plasma containing H2O. The first step which initiates removal of photoresist while simultaneously beginning the passivation process causes residue-free removal of photoresist following etching of aluminum or aluminum-copper layers in chlorine bearing etchants.Type: GrantFiled: June 26, 2000Date of Patent: August 7, 2001Assignee: Chartered Semiconductor Manufacturing Ltd.Inventors: Wen Jun Liu, Simon Chooi, Mei Sheng Zhou, Raymond Joy

Patent number: 5989979Abstract: A novel anisotropic plasma etching process for forming patterned silicon nitride (Si.sub.3 N.sub.4) layers with improved critical dimension (CD) control while minimizing the Si.sub.3 N.sub.4 footing at the bottom edge of the Si.sub.3 N.sub.4 pattern is achieved. A pad oxide/silicon nitride layer is deposited on a silicon substrate. A patterned photoresist layer is used as an etching mask for etching the silicon nitride layer. By this invention, a chlorine (Cl.sub.2) breakthrough plasma pre-etch forms a protective polymer layer on the sidewalls of the patterned photoresist and removes residue in the open areas prior to etching the Si.sub.3 N.sub.4. The Si.sub.3 N.sub.4 is then aniso-tropically plasma etched using an etch gas containing SF.sub.6. The polymer layer, formed during the Cl.sub.2 pre-etch, reduces the lateral recessing of the photoresist when the Si.sub.3 N.sub.4 is etched, and results in improved patterned Si.sub.3 N.sub.4 profiles with reduced CD bias, and minimizes Si.sub.3 N.sub.Type: GrantFiled: December 10, 1998Date of Patent: November 23, 1999Assignee: Chartered Semiconductor Manufacturing Ltd.Inventors: Wen Jun Liu, Pei Ching Lee, Mei Sheng Zhou
